Hi Great video! Would be great to see a video covering how to design a crossover from scratch, the roles played by every component in the crossover, ect. You covered up alot in this video but it would be great for novices! Anyway, clear and very informative, love your channel!
Ed DaPimp It's a huge subject but will be coming with time as I grow the channel. In a month or so Ill have a video walking you through a complete design/build. I'll be starting next after I'm done with a speaker meet this weekend. The more videos I'm able to do the more those tutorials will come. It's just such a huge subject to cover in one video. In the meantime feel free to ask any specific questions. Thanks for the support :)
I would like a a little more detail in a tutorial. Try watching your tutorial as a person that knows very little about Xsim and see what you get. In a tutorial you can't tell people you may have to guess on a answer, or I'll show yous that in a later video. Please don't take this wrong You doing a good job helping people. I think a simple 2way step by step would help more of your followers Thanks Jim
Jim Conard hi Jim. Thanks for the feedback. As mentioned at the start of the video, this wasn’t a tutorial for beginners. A certain level of knowledge is required for this to be helpful. Sorry. I hope to get more starter videos up on my channel over time.
@@ImpulseAudioSpeakers First off, it was not meant as a complaint on your video. If you thought so I apologies! You are doing very good crossover videos! I didn't explain myself very well. My though for you was to make a very basic video explaining every move in order so people could go back and see where they went wrong. That would grow your number of viewer. This is just my thoughts. Thanks again for help!
Jim Conard no problem. I didn’t mind your comment. I appreciate all feedback. That does clarify what you meant though. It’s a good idea. I’d like to do a video that makes the process as simple as possible, beginning to end. I need to find the time to do it though.
Thank your for introducing this fantastic software. I have been using Soundeasy since 2004 and Xsim is more practical and equally powerful. I also love using ARTA (licensed version) for measurements.
The hard part is measuring the speakers accurately and setting up all the gear to do the measurements, and the software, sound easy is a rather complicated program too.
Very Good Info in your Video. I actually watched it in slowmotion, to get the most out of it ! :D I would like to learn more about to compensate for the Z offset with a combined meassurment. Keep it on !
Bill Waslo No problem. Its pretty basic and hope to discuss specific features and ways of use eventually. If you ever want to provide input about what FAQs you get, you know how to contact me. Funny thing, I was still using the beta version I tested up until it was time to do this video. I discovered a few things when I downloaded the latest version. Glad I did that. Figured it was prudent to get the latest.
At this point you may know about it more than I do! Haven't used it since last year, though plan to soon. Maybe you could do a section on getting "classical" filter shapes (since so many new designers seem fixated on creating some Nth order Somethingworth responses (for no good reason I can think of nowadays, since measurement setups are so available, but it's probably the comment/question I hear most)
I have just one question. When purchasing your Inductors and Capacitors, how do you choose them based on the ESR value you entered for them in Xsim? I can't find any ESR values listed on the components (air coil or capacitor). For example an Aircoil of 1 mH with an ESR of 350 m[R].
Thanx for this tutorial. I was playing with Xsim month ago so i grasp god portion of app though it is not friendly to much to a newb :) i hardly wait my OmniMic. Cheers
Very interesting to build crossovers with the help from a computer but one question remain: How accurate is the result compared to the simulation? Since there is always a disparity between drivers in their response and impedence, how much can we rely on them? Plus, the quality of the components, cabinet construction and damping material can also affect the final result. I suppose it is only a set of variables in the total sum of what makes a speaker great or not. Great vid! Keep them coming!
They’re pretty darn accurate, but yes, an error in the driver follows that speaker. The more inaccuracies in a driver the more error. And of course your do need to listen and evaluate the design and tweak. The computer definitely can’t do that.
Fantastic tool, thanks a lot. I wonder where to find the frd file to simulate acoustic effect as you propose. I 'm using a wave guide so the SPL given by the manufacturer is not valid !
Do you know of a source for a very basic learning tutorial for Xsim? I know that is not what you intended on this video. I mean very beginner basic. I wanted to start making my own speakers, but I see now how I can't just use calculators online and expect good results. Thanks.
I think you’ll need to learn from many sources. My videos are a bit technical and advanced, but they might help give you some ideas. There are some good forums to read, such as the parts express tech talk. Use google too. Videos aren’t a great format to learn speaker design. Unfortunately text might be easier.
What all do you need as test equipment to fully test drivers yourself, if you don't know or can't find any "spec sheets" for the drivers you wanna use?
A decent calibrated condenser mic and a decent space to work. The software I recommend is REW and Xsim. I suppose you’ll also need a way to measure impedance. The DATS system is about the only choice for that.
@@JoeJ-8282 if on a budget, get the mini dsp mic or some other cheap mic for about $150. Then the DATS would be another $100 I’m guessing. Sorry I haven’t priced this stuff out in quite a while. If you are doing an active XO you don’t need the DATS.
@@ImpulseAudioSpeakers Wow, OK. More than I was hoping, but I guess I need to save up for a while if I ever TRULY want to Improve my game with speakers! I guess I ALSO need to get an actual computer first too though, because rn all I can afford is my cellphone that I watched this video on. And really I only have that, mainly because I need it to stay in touch with and use during work, i.e. my job. So far all I've ever done is basically do stuff with and try to improve speakers that I find for free in trash or recycle dumpsters, or sometimes I buy from my local thrift stores IF they are no more than $1/inch of driver diameter. That's my limit. AND they have to already sound pretty good before I buy them, and then I will take them home and tinker around with them and improve them the best I can by ear, and by using my basic knowledge of how crossovers work and such, along with all of the other more "subtle" things I've learned over the years that make speakers sound better. I only have a basic multimeter and a calculator to work with rn, and even though I DO have a really good ear for what sounds good and what doesn't, after literally 1000's of hours of experience in A/B comparison listening and experimentation, when I watch the REAL speaker building channels like this one, (and many others too), it just makes me realize that I really don't know much of anything substantial about speaker building in all actuality, even after all these MANY years of experimenting with NO budget, second hand speakers. I do what I can with what I have though, and it's at least fun and enjoyable and entertaining for me, even if it has to only be a casual hobby, because of time and budget... I love videos like this one though that show how awesome and cool and relatively EASY speaker designing and building CAN AND SHOULD really be, plus it gives me something to look forward to, if ever one day I can get enough money to actually buy me some REAL analyzer equipment and stuff like that! It's really amazing what all is possible nowadays with this type of stuff! Technology sure has come a LONG way since I was a kid and I started to be interested in this kind of stuff!
@@JoeJ-8282 you should check out the Panasonic condenser mic. It’s a mic capsule that costs about $2 and you can diy a mic with it. Pretty darn accurate. Can even diy an impedance jig if you want. They’re not great and not as accurate as the mic and jig I mentioned, but will really up your game for about $10.
In xsim you can choose value, open, and short for each component. I understand the first two but what is the purpose of short? Can you wire a capacitor in short? How?And why would you?
It’s just a convenient way of turning off the component. For instance, you could have a 3rd order crossover L, C, L and then short the 3rd leg, L, to see what a 2nd order crossover does. You could also short a resistor that you don’t want but might want later. That sort of thing.
Cám ơn bạn đã chia sẽ ạ. Bạn vui lòng cho mình hỏi mình sử dụng phần mềm nào để mình đo đáp tuyến của loa để file có đuôi là .FRD sau đó mình đưa vào phần mềm Xsim mình làm vậy bạn. Cám ơn bạn rất nhiều!
Hi Impulse Audio! Awesome video, have a question however! Idealy do we want those phase lines on the drivers to be in line as possible? so they are all ontop of eachother, or do we want them parallel? Also lets say when modelling around with drivers, blah blah and we invert the polarity on one of the drivers and barely anything happens, is this bad? Thanks buddy!
Quake Audio this is a pretty big topic you’re asking about. There are exceptions but yes you want the phase to be on top of one another. Then the drivers will be in phase and offer the most tweeter protection and woofer breakup suppression as possible, and some other stuff. The phase really only needs to overlap across the XO region. It’ll be impossible to get them to overlap for the entire frequency spectrum.
Hi and thanks for the awesome tutorial. I have a question. Is there a way to simulate the frequency response by taking the box dimensions into account? I'm speculating that the woofer sensitivity will lower a bit and the tweeter will remain the same, which means that I'll have to compensate with a resistor to keep them even. Is there a tool for that and is my guess correct? Thanks
This is really cool. A bit over my head at this time, but cool. Yeah, I think I would like to try to design my own speaker at some point. Any advice on how to deal with crossover as a newbie would be appreciated. Curious why designers never use oval speakers: wouldn't having a speakers' surround closer to the edges of the cabinet increase the soundstage? Or maybe not? I think of GoldenEar Tech: They designed their speaker cabinets narrow with narrower fronts to allow for greater disbursement. Eh, just a thought.
I ran 2 woofers in series but I can't get the line to show on my graph and I noticed you didn't try to bring it up on the graph. Would it be just the same as the single woofer?
Two woofers in series produce the same SPL as one, despite being 3db more efficient. That’s probably why your line didn’t change. If you need it louder, try parallel. But then the impedance will drop in half, so be careful.
That level of power is only going to be at very short bursts. Milliseconds. Also, I usually put a couple of resistors in parallel, essentially doubling the power handling. I’ve personally never had a resistor burn up, but if it happened they’re easy to replace.
In a first order filter, for example for a tweeter, does it matter if the attenuation by a resistor is put before or after the capacitor? Or is it the same?
It does matter because if it’s after the capacitor must be smaller for the same affect. Either can work just find though. Sometimes I put a resistor before AND after the cap to get the outcome I want.
Hi ! You make greate videos! I was wondering about impedance, that curve at 9:29, is that ok? I really dont know, so if my results look like that can I be happy? Thx!
Excellent video. One thing I wonder : do you use frd/zma files measured in free air or with drivers mounted in the enclosure ? PS : would be a good idea to buy a mike and some absorption panels.
didierleclerc66 I measure in the box for XO design. Better results that way. Ya I’ve improved but still not a “pro” CZcamsr. Not really trying to be either. Just doing it to help.
Can you make video start from basic to get driver files and all associated files and by using xsim to get how to make really reliable crossovers? I have bought Tyler acoustic 3 way mastering speakers which equipped with dayton RS-180-8, RS-270-8 and unnamed tweeter. I really like the very open space detail sound come out of the box, but they are bump around +5db on 3-5k and huge dip around 250-300hz so as a result the sound is so clean. I paid a lot of money to shipping and I want to keep them and work on them just because they are well constructed.
There's a lot of information to pack into one video to get from start to finish, but I will keep adding videos about how to measure and get information for XO design. Is there something specific that you're struggling with understanding?
since I played your video a bout 100 times, I got to the point choosing components. And I got .frd and .zma files off from partsexpress. Now I am going crazy putting on the graph to get flat response. Can you help me with the graph? I will pay for your service. My email thagek@gmail.com
What part are you struggling with? I'd rather help you get to a solution and learn than get paid to do it for you. But I don't mind making some suggestions either.
Thank you for your kind heart. I am struggling on first crossover point between tweeter (I picked dayton tweeter from partexpress) and RS-180-8 mid driver. I just can't make that crosspoint work.
Vic G I do have a Vifa midrange tested and reviewed you can watch, but nothing HiVi yet. This channel is just starting so possibly hivi in the future. Watch for a test and review of the Vifa XT25 tweeter. No Vifa woofers though. I do have some cheap Peerless woofers here but they are 5.25" and wouldnt make sense in a 3 way.
hello! I want to set up a crossover that can modify a curve of a mid-woofer that I have, because at around 70 Hz or so, when I put into the enclosure that I've designed, sounds really bad... and there is little I can do with the enclosure, and I was wondering if it is possible to attenuate that frequency using the crossover... I've noticed when you modified the "mod sensitivity", the whole woofer curve dropped a few decibels, but I don't know exactly if that changes something (?)
You can do this easily with eq or moving the speakers around in the room. Basically impossible using passive crossover components. The room is likely causing a boom sound at 70hz more than the cabinet.
@@ImpulseAudioSpeakers That's what I did... adjusting the volume, or the pots of my preamplifier, and it did something to a degree, but still... at a distance of about 1.5 meters or so, that booming sound was so loud, that I had to cover my ears... So you say that its the room... I could be... the cabinets are 1100/220/300 (H/W/D in millimeters), and my poor room has 3.5 by 3.5 meters, and it's not soundproof! In a way I am glad that is the room! :) Thank you very much! 🙏
i started on xsim a few days ago i want to make a 3 way crossover but because i have professional components, the frd and zma files weren't available i have the sica 10fe 3 cp 8Ω woofer the sica 8m 1,5cs mid and the visaton sc 10 n tweeter i'll send the pdfs too.Now i got the curves from graph tracer and edited them, with paint 3d i erased everything except the frequency and impedance charts everything works in xsim, i noticed tho that the curves of the drivers, are not aligned with the x and y axes of xsim based on the factory pdf. Is it possible to adjust the axes of xsim so that the curves appear as they do in the factory pdf?? and if so how? As you guys can see for yourself in the crossover photo i sent the frequency of each driver if you compare them to the factory pdfs does not align they start at more hz and more dbs i would really appreciate an answer cause i cannot align them.
Hello! Thanks for sharing this amazing knowledge about crossovers... and thanks for the hint with Xsim! Wonderful program! I was wondering, very few are using series crossover networks, and I don't know why!? I have built some crossovers of first or second and even thrird order, parallel vs series, and ... they sounded better on series! On the parallel versions I had to use several parts to obtain what I wanted (using Xsim, of course), but in series... I've just needed a few components, and on the Xsim it showed exactly what I wanted almost immediately! I know, of course, that if I needed to change one component it affected both drivers at the same time... it is a disadvantage! But, seriously, its sounds much better! What is the science here, anyways?? Is it the taste only? Is it the drivers? Or the room for that matter...? I don't know... I've always used a midwoofer (6.5") and a dome silk tweeter! The midwoofers were eighter with paper cones or kevlar cones and rubber surrounds! Nothing else whatsoever! Every time when I built series crossovers, the midwoofer was on the first order, whilst the tweeter varried from first order to second order... when I used second order for the tweeter, it was Linkwitz-Reily!
They can work very well but are a pain to design. Parallel cross overs let the design mash the driver into submission without affecting the other driver. It’s a real trick getting series to work. But they certainly work just fine. I’m not sure there’s actually a sound quality benefit, but if it works for you go for it.
What is the mod delay used in the Select Driver menu? Can't you tell which parts are being calibrated or which parts are being used for speakers or which parts are being replaced?
Maz 4bz I did. I might not have shown that in this video because it was about how to use the software, but I usually do. Note that method is not always necessary.
That is just the resistance of the inductor. Usually about 0.3ohm for a small inductor and 0.5 for a medium to large inductor. Some are up to 1.0ohm if they’re big air core and small gauge. Usually labelled on the inductor or you can just put a multimeter on it and measure the resistance. It’s not a critical item to get right most of the time.
Hi, thanks for the tourtorial. I would like to add the circuit block to take out a notch in my system but I can't find the circuit blocks. Did you download the circuit block function elsewhere?
If I have two bass driver mounted in a cabinet and the load is 4 ohm at the low pass filter crossover point. If I add a further two bass drivers, would this change the response for what the crossover was designed for. 4 ohm....
The version in the link doesn't have the Baffle pull down. The version that does is in the BetaTest folder but the Baffle pull down is greyed out and doesn't work. Is there a current accurate link to the most current fully working version? Thanks.
Hi Ryan I've watched your videos about using XSim crossover design software and I think I understand how to use it, but I have a question about working backward, so to speak. In other words, let's say I don't have ZMA or FRD files, but I know the actual crossover components and their values. Is there software I can use to determine the crossover frequency, or any of the driver values of drivers that could be used? E.g.: impedance, FS Q parameters or even expected frequency response curves. Btw, I really like your youtube channel, and I always look forward to new videos. Thanks
Ed Incleve hmm, I’m not aware of that sort of software. Would be really tricky without the files. A lot depends on the frequency response where the XO point is. Sorry.
Thanks for a great video. I'm noticing that the mod delay for my woofer is making a significant difference to my frequency response and would like to put in an actual value, or even better offset my speakers when mounting in my cabinet. At which location on the speaker do I use to measure mod delay?
jpc6204 it’s easiest to measure both drivers individually and also wired in parallel, without moving the mic. Then in Xsim add the graph of them wired in parallel as an overlay. Then adjust delay until the response aligns with the parallel measurement. This will give you the proper delay. It’s fairly important to do right to get good results, but if in doubt about 25mm usually works.
@@ImpulseAudioSpeakers Got it, thanks! I also saw another video you had entitled "Life S5 | Part 3: Design Goals and Setup," which walked me through the process. You're gonna make me a master speaker builder in the coming months!
When this program starts, you'll get the speakers.When you call in two twitter and woofer, if you synthesize an RTA graph, the graph sometimes goes over the screen too much, and the dB difference between the speakers is more serious than you think.In this case, how is the setting correction year right? 음성듣기
hello, Im building 2 way crossover with 2nd on bass and 3rd order on tweeter. crossover line is 5000hz, and the graphics of the bass speaker and tweeter overlap a bit, and in general it turns out smooth. but the blue line called the system rises at the junction . that does it mean?
lol lol that means both the tweeter and the bass are playing in phase together so both outputs are creating more output at the XO point than the rest of the system. There will be a peak in the response that may or may not sound good. Probably best to adjust the XO a bit to flatten that peak down a bit. Depends how big it is though.
Could you please point me to the place where I can find driver files for B&W 802 S3? I used Xsim to simulate XO for B&W 802 Se using default Xsim files and got perfectly tuned XO, but I suspect that my XO far from perfect because I do not have real B&W 803 S3 files.
Fred Kleytman you are right that actual driver files will make a big difference. Unfortunately I don’t know where you could get the files for that driver. I doubt many people have measured them. Unlikely you’ll find them.
Honestly, you have to measure the drivers like you see me do in some of my videos. You could also look for them for other drivers, but be sure the baffle size is the same. Most drivers are tested on a very large baffle which we don’t use in our homes.
@@ImpulseAudioSpeakers thank you sir. Here in the philippines they are not incline to use dividing network. We rely to ready made dividing network from online seller.
If I’m understanding your question correctly, yes phase should align at and through the crossover region. It doesn’t actually have to, but I believe it’s the best way to design it as you get the most tweeter protection and stuff.
@@ImpulseAudioSpeakers ah, yeah that makes sense. Was just unsure if I'd just been going above and beyond to what wasn't needed but I just forcive habit. I also try to make impedance phase as flat as I can as well, although probably really not needed, certainly isn't something I hear anyone really chasing. I'm of a good understanding of impedance, but impedance phase in speakers is a job to find an explanation of how it's beneficial.🤔 Any ideas on that one? Is it something you have ever tried for any reason?
@@zefrog7482 I really don’t concern myself with impedance other than ensuring it doesn’t go too low. Especially at low frequencies for a wide band of frequencies. If it goes down to 2ohm at 8khz, or something like that, I don’t get too concerned. 3ohm from 60 to 200 hz is a problem for some amps.
Great video, Does this software also have the ability to simulate drivers when installed in an enclosure? and does/can it take into account front baffle size (bafflestep?) too??
It uses the measurements you provide. So if you measure in the baffle/enclosure you’ll capture the baffle step loss. I think it does have a baffle simulation feature but not too familiar with it.
Hello, this tutorial is awesome! I'm trying to design a 3-way crossover for my 3-way speakers right now, with real measurements i got through REW. i was able to get a decent flat response like yours, but the overall impedance curve got awry. It changes between 3-19 ohms, with 2 major peaks and 2 minor bumps. You didnt mention much about the total impedance result, what should be our target when designing an XO? Is the combined impedance important for the performance?
klazzera Impedance definitely requires considerations, but if you're using a modern solid state amp you don't need to get too fussy. The higher the impedance the easier the load on the amp. 3 ohms isn't to bad, but its a tad low. And the curve doesn't need to be flat. John Atkins of Stereophile comments on impedance in the measurements section of that magazine and can be helpful to read the types of things he finds on different commercial speakers.
thanks for your quick reply! so let's say my amplifier is rated at 60 watts at 8 ohm, does that mean any impedance value above 8 ohms mean that my amplifier power output is less than 60 watts at those regions so i should compensate with using a higher wattage amplifier for those impedance peak regions? I'll also have a look at the magazine you mentioned
klazzera yes the output will be less than 60 watts but thats not a bad thing and it definitely doesn't need to be compensated for. It just means the speaker is more efficient at those spots and the amplifier doesn't have to output as much. It's the low impedance spots that can give your amp troubles. Think of the high impedance like a benefit.
oh okay i get it, further tweaking on the frequency response i realized there are some 0.5ohm impedance dip points have appeared, i guess i'll need to fix those first. I guess i should keep the whole impedance curve above 3-4ohms. thank you so much for your help!
Cool video, thanks! Do crossover simulation programs not take into account total sound power (e.g 30 and 60 degrees off-axis response)?? I also can't seem to load frd and zma files traced from FPGGraphTracer. I keep getting a "file load error!". Any idea?
Not sure why you’re getting the load error. No they don’t usually show sound power (power response). Most will allow you to pan off axis and as the designer the off axis should be measured.
It’s been a while since it was developed. Maybe it’s not offered anymore. That would be a shame. Or try the non-secure link. It’s just a buddies website. He won’t hack you if it’s his.
@@ImpulseAudioSpeakers I managed to download it thx, was looking for your video on how to download drivers, I need one for a seas excel woofer and tweeter.
I been using xover pro and bass box pro I purchased off of parts express. Has anybody else used these, are they any good? I been using them for years and really like them but have nothing to compare them to.
Subscribed. Love your videos. I almost ordered 5 crossovers by Dayton sold at partsexpress, crossed at 2500hz. Basically I've gotten PSB T65 Drivers, tweeter and woofers, cabinets were destroyed by the original owner along with the crossovers. I'd really like to somehow contact you or get more help on how I could go on about designing them completely to perfection, as I can't find their data sheet anywhere at all. Thankyou :)
Rohail Butt hey glad you saved your money. Tricky situation though as you would need to measure the drivers. If you could find a spec sheet you could at least get some data files based on that.
Thankyou for your response! Well I contacted PSB and got a reply, they are not helping me either. So basically i've wasted my money and nothing will come good of it?
Rohail Butt they won't tell you what the original schematic was? Can they at least sell you new XOers? What is the damage? I wonder if they can be repaired...
Rohail Butt ouch. Hmm, if you can't get your money back the best thing may be to use a generic crossover temporarily and use the speaker to learn. Or maybe reuse the cabinets to start a new project that has been proven properly.
Is this software ever updated? I thought it would have a home page, but i cant find it, everything i find relates back to 2014, i'd think by now they would have made leaps and bounds of progress.
Nosajjao if the sensitivity of the tweeter is much higher than the woofer (which is common) then the input to the tweeter needs to be restricted using resistors. It also helps protect fragile tweeters. Big amps are mostly for the woofers.
Ryan, please advise me on the location of that CircuitBlocks file folder. It somehow disappeared from XSim program that I just installed and used for a first time tonight. Instead of that folder "CircuitBlocks" button now gets me to the folder where I've stored FRD and ZMA data. And my laptop also can't find the "CircuitBlocks" folder on a hard drive. So now I can't use any blocks. But I used one of the blocks a bit earlier just before I've loaded driver data.
I’m not sure what is happening for you. It should be along the top menu, but I’ve never had that problem. To be honest, I don’t use circuit blocks very often, even though they are useful. So maybe I am missing it too.
@@ImpulseAudioSpeakers I have figured out what had happened. When I finished working on a project last night I have decided to save it using "Save As" option. The program offered to save the file in the "CircuitBlocks" folder. But I instead have chosen my own folder elsewhere. After that, every time I tried to use that "CircuitBlocks" button on the top menu the program would offer me to load blocks from that same folder where I saved my project. However, that folder has no any crossover blocks in it. Then I have tried to find that folder named "CircuitBlocks" on my computer but the Basic Windows 7 could not get it. So, this morning I have asked a friend of mine and fellow speaker builder to install this program on his machine. He then opened the "CircuitBlocks" option window and told me the path to that folder on a hard drive. That was my question, Ryan (the location of the folder). Now, that's where it can be found: \\[Name of your computer]\Users\Public\XSim\CircuitBlocks
Hello sir.... I'm testing woofer with DAT V3 and modelling with Bass box 6....pls HOW DO I UPLOAD T/S PARAMETERS ....or those those files you took from your laptop..
@ Impulse Audio..... Whats the difference between a series and shunt notch filter? I was looking at trying to reduce a 7db peak at 15KHz of a tweeter. Also, What do you do to raise a dip in the frequency response of the system?
bsl bl a series botch is a weird name because it’s an inductor, capacitor, and resistor all in parallel, but that set of components is in series with the driver. A shunt (or parallel) notch is the opposite. In parallel with the driver but the parts are all in series. The series notch would be best for a 15khz peak but shunt could potentially work there. Shunt notches can really lower impedance if you’re aggressive and in the driver’s bandwidth. Dips are really hard to fill passively and depends on where and how. Possible to fill it by using the tweeter padding and filter. Certain things can work. Dips are less of a problem than peaks, and some dips shouldn’t be filled. Such as those caused by diffraction.
Thanks Ryan. I guess the name series notch is because the notch is in series with the driver and the shunt notch is so called because it is in parallel to the driver. So, I notice that to get the peak down, I need to go to about 60 to 70 ohm resistor value in the series notch. Is that something normal?
bsl bl no that’s not normal. Have you adjusted the inductor and cap to try and widen out the Q factor? 7 dB at 15khz is somewhat odd. What driver is this and how was it measured? If the data is good I would keep working at it and see what you can do with it.
ozy prima doesn’t need to be flat. There isn’t really much need to focus on the impedance curve other than to make sure impedance doesn’t go too low and cause problems for your amplifier.
great and informative video! would you happen to know any program that i could extract/copy/trace the FRD and ZMA files with based on driver SPL graphs? i have Visaton drivers but i can't find any data files for them online..i read about a program called SPL Copy or smth but its not available anymore..atm i'm using Boxsim for crossover design but it's kind of confusing for a newbie like me hope you can help :)
Martin Ahven the only one I'm aware of is SPL trace but I think that's probably the one you're thinking of. If it's not available anymore I'm not sure what to say. I know another channel called 123Toid has done a video about it, so you could check there. You can also manually do it but that would take forever.
@Martin Ahven: I tried FPGraphTracer but it sometimes recognises the wrong lines depending on where you click. You might have to compile one file from parts of several files. If you use Visaton drivers you should definitely play around with BoxSim. If you speak German watch the BoxSim tutorial by "Leo Lautsprecher". It's really good! Maybe also watch my tutorial about crossover design where I used BoxSim but don't explain much: czcams.com/video/5Kvl0iBQ0L0/video.html.
great tutorial, but I really struggle building a nice and simple crossover for the Dayton nd105-4 4 and the Dayton ND25TA-4 (50W per channel) , can anyone help me?
maped345 a lot of people have recommended it, but I haven’t found an advantage. I like software that is simple and to the point. Which is part of why HolmImpulse is actually my favourite measurement software even though it’s not popular. Xsim has a lot of power built into it, but the core of it is very straightforward.
toad cut I’m not sure. I’ve never used their files. There should be 2 files for each driver. 1 frd and 1 zma file each. So 4 total kind of makes sense.
Max B. Simonsen I think the minidsp umik is pretty cheap at around $100, and is perfect for the job. But if that’s pushing the budget try google Panasonic WM61 capsule. I might not have that quite right, but it’s a DIY mic you can build for about $5. Not bad either. You’ll want to upgrade in the future but worth using it to learn.
Hellow Ryan! I hope u r good. I got a confusión about pre-design crossovers. As we know, there are lots of crossover labels in the market. All of them with a specific cut of freq and components. let's use, for instance, the Dayton XO3W 375/3k. If we are looking for those specific cuts, what's gonna happen is that... we're going to buy that crossover because it supposed that is gonna work, but as soon as when designing our crossover for our system in Xsim and we put those values of those components of that pre-design crossover to see how it going to behave and for achieving those cuts entering the FRDs files, they change a lot. Those values are not the same anymore. My confusion is...when that label built that crossover, they built it base on what? Because and,-correct me if I wrong but,- I don't think they come with a manual saying: "oh, by the way, this crossover works perfectly just with eminence speakers oooorrrr whatever". I don't know if u get me, bro, ooorr maybe I'm missing something or I'm still ignorant of something. Can u help me with this? or can u make a video showing whether if it is true or false or something educational about this the way u did in the video on "whaty not to use online crossover calculators?" Thanks, Ryan.
Joseph Anselmo you are correct. Those things are junk. And I actually did make a video sort of about it. It's called something like "why to NOT use online crossover calculators". Those prebuilt crossovers are based on perfect flat 8ohm loads without any deviation from flat and assume phase is perfect. They never work.
andythewooferguy I dont have any Beyma drivers to be honest. I have Eminence and Celestion from the PA world that I will eventually review and post the measurements. But nothing Beyma. Is there a specific model driver you are interested in? I could see about eventually getting one or two of them to try if I have a need.
andythewooferguy Yes. If you look at my other videos I have 3 or 4 driver reviews. Just getting started. There will be many more. Next is the Motus UH205PW1 and then the Denovo Magnum 12. Ill look up those Beyma drivers and see if I can find a use for any of them.
I created frd filefrom curve and icant load it. It says File load error, followed with name of file. I traced curves in FPGraph tracer. When i compared frd which came with app with mine i noticed i have only two columns of numbers but these frd files have three columns with numbers?? I am confused
Zox Wolf it needs three columns. Frequency amplitude and phase. You can even just add 0 for phase on the whole thing. But you’ll need to extract minimum phase in that case. I show how to extract minimum phase in my Life S5 series, about part 4 or 5.
@@ImpulseAudioSpeakers Thanx mate, I manage to make frd and zma file but as you said phase is 0. I will check your other videos. How much accurate is this? I noticed that i need to adjust scaling (vertical center and vertical value) on right windows othervise i cant see my frequency and impedance curves. I traced original dynaudio graphs in corel and than in FPG tracer. I am planing to get DaytonAudio OmniMic V2 with software. Do you think it will export FRD and ZMA files as it should.I am still confused bout using this Xsim :( Cheers mate
Zox Wolf without phase it’s not accurate. But you can extract minimum phase which is accurate to a point. Difficult to explain. Omnimic or any mic like that will give you the frd files. Zma files are different and require an impedance tester. All this can be quite confusing. I keep planning to make a video showing the process from beginning to end but it’ll be quite a bit of work.
@@ImpulseAudioSpeakers Thanx for your explanation. I intend to get DATS V and OmniMic V2 from Dayton Audio :) I will closely monitor your channel for tutorials .. Cheers mate
Where the hell is the XSim website to purchase the latest version? I have the free download version, but cannot find their website to give them money? Do they exist? No website link in the about section of the free version. I have never seen software where you cannot find their website.
John Johnson ya he’s kind of gone into retirement. The free version is the only version. When he made it I asked him about support and stuff. He said he did not want people contacting him but did want to offer it free. I think he didn’t want to have to field all the support emails. If he knew people wanted to give him money he may have made a website 😆
Cary Phillips you would either need to measure them, which is another entire subject on how to do that, or somehow get the files from another source. There is a program called SPL trace that creates frd and zma files from the manufacturers spec sheet. What sb and vifa drivers do you have? I will be measuring the sb13pfc25-04 next and also the vifa XT25SC90-04. I may also have others.
Thanks for your reply, 1 ; I am building a 3 way with the SB acoustics SB29RDC-C000-4 Tweeter, the SB 12NMRX25-4 Midrange and the SB23NRXS45-8 Woofer. 2 ; I Am also going to design and build a switchable Super tweeter using the VIFA XT25SC90-04 with 3 crossover points and 3 sensitivity points for system matching to various speaker systems. I thought this software would be very useful. Regards Cary
Cary Phillips of those I only have the Vifa XT25SC90-04 and will be testing it next in fact. I currently have it in a box ready to go. It's going in my latest video and should have test results within a week. You'll be able to download the files and try them in xsim to see what could potentially work for you.
I do have the SB29RDCN-0004 but it is slightly different being the neo version. Could get a test of those though, if it would be helpful. It would have to wait though.
I measure the drivers and then the software provides them from the measurements. I post the measurements for all my driver test if you look in the video description.
@@ImpulseAudioSpeakers hey thanks for such a quick reply I have studied this video many times over, is it ok if I send u an email to ask a few questions? is there a community address? Thanks!
Kempo I’m pretty slow and replying and have had to step away from speaker stuff for the next 6 months while we go through and extensive addition. But I can be reached at ryan@impulseaudio.ca
You need to use measurement software such as Room EQ Wizard or HolmImpulse. You can also change a .txt file into a .frd but the txt needs to be in an frd or zma format.
@@ImpulseAudioSpeakers Thank you, I know that. I use LoudSpeaker LAB 3 for measurements, but unfortunately it cannot export frd or zma, which is why I ask which one are you using.
Great info. Maybe for the newbie if u have time u could do a short video to explain what is the attribute in a crossover of a capacitor, inductor, resistance. For example: u use a inductor on a tweeter.. if u want lower the impedance or frequency. Or u use an extra coil on the midbass to cut the upper frequency and a capacitor to do something... :D(i have no clue what i'm saying but u understand the idea) ps: subbed :D
at 1:24, you open the file in the folder - SPL response (.frd). please tell me how to make a .frd file for your speaker. if possible, make a short video)) it will be more clear. I will use a translator who translates poorly.
One Gogh You need to measure the driver, or you can download measurements of any drivers I have tested on the channel. Link to the measurements is in the description of all my driver test videos. I will be doing a video that will help with this soon. It will be about how to measure and test a speaker and then design the cross over.
@@ImpulseAudioSpeakers good evening. I want to make a measurement of the speakers beyma 10 wrs300. load data into your program. do not know how. to use it with fountek tweeter.
One Gogh do you have a mic? You’ll need that at a minimum. You might want to ask Beyma if they have the measurement available. Or search the web for it.
@@ImpulseAudioSpeakers Yes, I have a microphone. Beyma has data on the speaker. the speaker will come soon. if it’s not difficult for you, show how you do it))
Vladimir P sorry I’m not sure I understand the question. Are you asking where the drivers go on the screen? They go on the component layout window. It’s supposed to look like a circuit board.
@@ImpulseAudioSpeakers I meant the location of the drivers on baffle. For example, if I position the tweeter 60 mm to the left or higher or lower. How does XSim understand what driver placement I made in my project?
Vladimir P you should see my follow up video that shows the baffle functions of Xsim. But you really don’t need it. Always keep the tweeter as close to the mid or woofer as possible.
Hi Great video! Would be great to see a video covering how to design a crossover from scratch, the roles played by every component in the crossover, ect. You covered up alot in this video but it would be great for novices! Anyway, clear and very informative, love your channel!
Ed DaPimp It's a huge subject but will be coming with time as I grow the channel. In a month or so Ill have a video walking you through a complete design/build. I'll be starting next after I'm done with a speaker meet this weekend. The more videos I'm able to do the more those tutorials will come. It's just such a huge subject to cover in one video. In the meantime feel free to ask any specific questions.
Thanks for the support :)
I would like a a little more detail in a tutorial. Try watching your tutorial as a person that knows very little about Xsim and see what you get. In a tutorial you can't tell people you may have to guess on a answer, or I'll show yous that in a later video. Please don't take this wrong You doing a good job helping people. I think a simple 2way step by step would help more of your followers
Thanks Jim
Jim Conard hi Jim. Thanks for the feedback. As mentioned at the start of the video, this wasn’t a tutorial for beginners. A certain level of knowledge is required for this to be helpful. Sorry. I hope to get more starter videos up on my channel over time.
@@ImpulseAudioSpeakers First off, it was not meant as a complaint on your video. If you thought so I apologies! You are doing very good crossover videos! I didn't explain myself very well. My though for you was to make a very basic video explaining every move in order so people could go back and see where they went wrong. That would grow your number of viewer. This is just my thoughts. Thanks again for help!
Jim Conard no problem. I didn’t mind your comment. I appreciate all feedback. That does clarify what you meant though. It’s a good idea. I’d like to do a video that makes the process as simple as possible, beginning to end. I need to find the time to do it though.
Thanks for the tutorial. I'm still toying with Xsim, but learning. I have a long way to go, so far, but this is a great starting point!
Thank your for introducing this fantastic software. I have been using Soundeasy since 2004 and Xsim is more practical and equally powerful. I also love using ARTA (licensed version) for measurements.
The hard part is measuring the speakers accurately and setting up all the gear to do the measurements, and the software, sound easy is a rather complicated program too.
100% correct. Getting clean data is difficult.
Very Good Info in your Video. I actually watched it in slowmotion, to get the most out of it ! :D
I would like to learn more about to compensate for the Z offset with a combined meassurment.
Keep it on !
Thank you for making these great vids, I have found them incredibly inspiring!
Thanks for doing this tutorial, Ryan.
Bill Waslo No problem. Its pretty basic and hope to discuss specific features and ways of use eventually. If you ever want to provide input about what FAQs you get, you know how to contact me.
Funny thing, I was still using the beta version I tested up until it was time to do this video. I discovered a few things when I downloaded the latest version. Glad I did that. Figured it was prudent to get the latest.
At this point you may know about it more than I do! Haven't used it since last year, though plan to soon.
Maybe you could do a section on getting "classical" filter shapes (since so many new designers seem fixated on creating some Nth order Somethingworth responses (for no good reason I can think of nowadays, since measurement setups are so available, but it's probably the comment/question I hear most)
I have just one question. When purchasing your Inductors and Capacitors, how do you choose them based on the ESR value you entered for them in Xsim? I can't find any ESR values listed on the components (air coil or capacitor). For example an Aircoil of 1 mH with an ESR of 350 m[R].
I’ve never found that to be a problem. It’s usually always listed. Perhaps labelled resistance or DCR?
@@ImpulseAudioSpeakers I was able to determine that 350m[R] is 350 milliohm which converts to 0.35 ohm. Thank you!
Thanx for this tutorial. I was playing with Xsim month ago so i grasp god portion of app though it is not friendly to much to a newb :) i hardly wait my OmniMic.
Cheers
Another great video. Looking forward to the next installment.
Very interesting to build crossovers with the help from a computer but one question remain: How accurate is the result compared to the simulation? Since there is always a disparity between drivers in their response and impedence, how much can we rely on them? Plus, the quality of the components, cabinet construction and damping material can also affect the final result. I suppose it is only a set of variables in the total sum of what makes a speaker great or not. Great vid! Keep them coming!
They’re pretty darn accurate, but yes, an error in the driver follows that speaker. The more inaccuracies in a driver the more error. And of course your do need to listen and evaluate the design and tweak. The computer definitely can’t do that.
Lovely software. Thank you for the video
Fantastic tool, thanks a lot. I wonder where to find the frd file to simulate acoustic effect as you propose. I 'm using a wave guide so the SPL given by the manufacturer is not valid !
If you go to one of my driver test videos, I have a drop box link in the description.
Do you know of a source for a very basic learning tutorial for Xsim? I know that is not what you intended on this video. I mean very beginner basic. I wanted to start making my own speakers, but I see now how I can't just use calculators online and expect good results. Thanks.
I think you’ll need to learn from many sources. My videos are a bit technical and advanced, but they might help give you some ideas. There are some good forums to read, such as the parts express tech talk. Use google too. Videos aren’t a great format to learn speaker design. Unfortunately text might be easier.
What all do you need as test equipment to fully test drivers yourself, if you don't know or can't find any "spec sheets" for the drivers you wanna use?
A decent calibrated condenser mic and a decent space to work. The software I recommend is REW and Xsim. I suppose you’ll also need a way to measure impedance. The DATS system is about the only choice for that.
@@ImpulseAudioSpeakers How much does all of that stuff cost? I'm on a VERY limited budget!
@@JoeJ-8282 if on a budget, get the mini dsp mic or some other cheap mic for about $150. Then the DATS would be another $100 I’m guessing. Sorry I haven’t priced this stuff out in quite a while. If you are doing an active XO you don’t need the DATS.
@@ImpulseAudioSpeakers Wow, OK. More than I was hoping, but I guess I need to save up for a while if I ever TRULY want to Improve my game with speakers!
I guess I ALSO need to get an actual computer first too though, because rn all I can afford is my cellphone that I watched this video on. And really I only have that, mainly because I need it to stay in touch with and use during work, i.e. my job.
So far all I've ever done is basically do stuff with and try to improve speakers that I find for free in trash or recycle dumpsters, or sometimes I buy from my local thrift stores IF they are no more than $1/inch of driver diameter. That's my limit. AND they have to already sound pretty good before I buy them, and then I will take them home and tinker around with them and improve them the best I can by ear, and by using my basic knowledge of how crossovers work and such, along with all of the other more "subtle" things I've learned over the years that make speakers sound better.
I only have a basic multimeter and a calculator to work with rn, and even though I DO have a really good ear for what sounds good and what doesn't, after literally 1000's of hours of experience in A/B comparison listening and experimentation, when I watch the REAL speaker building channels like this one, (and many others too), it just makes me realize that I really don't know much of anything substantial about speaker building in all actuality, even after all these MANY years of experimenting with NO budget, second hand speakers.
I do what I can with what I have though, and it's at least fun and enjoyable and entertaining for me, even if it has to only be a casual hobby, because of time and budget...
I love videos like this one though that show how awesome and cool and relatively EASY speaker designing and building CAN AND SHOULD really be, plus it gives me something to look forward to, if ever one day I can get enough money to actually buy me some REAL analyzer equipment and stuff like that! It's really amazing what all is possible nowadays with this type of stuff! Technology sure has come a LONG way since I was a kid and I started to be interested in this kind of stuff!
@@JoeJ-8282 you should check out the Panasonic condenser mic. It’s a mic capsule that costs about $2 and you can diy a mic with it. Pretty darn accurate. Can even diy an impedance jig if you want. They’re not great and not as accurate as the mic and jig I mentioned, but will really up your game for about $10.
In xsim you can choose value, open, and short for each component. I understand the first two but what is the purpose of short? Can you wire a capacitor in short? How?And why would you?
It’s just a convenient way of turning off the component. For instance, you could have a 3rd order crossover L, C, L and then short the 3rd leg, L, to see what a 2nd order crossover does. You could also short a resistor that you don’t want but might want later. That sort of thing.
Cám ơn bạn đã chia sẽ ạ. Bạn vui lòng cho mình hỏi mình sử dụng phần mềm nào để mình đo đáp tuyến của loa để file có đuôi là .FRD sau đó mình đưa vào phần mềm Xsim mình làm vậy bạn. Cám ơn bạn rất nhiều!
Hi Impulse Audio! Awesome video, have a question however!
Idealy do we want those phase lines on the drivers to be in line as possible? so they are all ontop of eachother, or do we want them parallel?
Also lets say when modelling around with drivers, blah blah and we invert the polarity on one of the drivers and barely anything happens, is this bad? Thanks buddy!
Quake Audio this is a pretty big topic you’re asking about. There are exceptions but yes you want the phase to be on top of one another. Then the drivers will be in phase and offer the most tweeter protection and woofer breakup suppression as possible, and some other stuff. The phase really only needs to overlap across the XO region. It’ll be impossible to get them to overlap for the entire frequency spectrum.
Hi and thanks for the awesome tutorial. I have a question. Is there a way to simulate the frequency response by taking the box dimensions into account? I'm speculating that the woofer sensitivity will lower a bit and the tweeter will remain the same, which means that I'll have to compensate with a resistor to keep them even. Is there a tool for that and is my guess correct? Thanks
If you measure with the drivers in the box, like I do in my other vids, then the box effects will be taken into account.
Great series of video's - can we share your content to others who are wanting to learn?
The Sound Guy yes please share it with anyone.
Thanks for sharing!
Please share more 2-way xsim tutorial
This is really cool. A bit over my head at this time, but cool. Yeah, I think I would like to try to design my own speaker at some point. Any advice on how to deal with crossover as a newbie would be appreciated. Curious why designers never use oval speakers: wouldn't having a speakers' surround closer to the edges of the cabinet increase the soundstage? Or maybe not? I think of GoldenEar Tech: They designed their speaker cabinets narrow with narrower fronts to allow for greater disbursement. Eh, just a thought.
I ran 2 woofers in series but I can't get the line to show on my graph and I noticed you didn't try to bring it up on the graph. Would it be just the same as the single woofer?
Two woofers in series produce the same SPL as one, despite being 3db more efficient. That’s probably why your line didn’t change. If you need it louder, try parallel. But then the impedance will drop in half, so be careful.
@@ImpulseAudioSpeakers I ran 2 4 ohm in series for 8 ohms if I run parallel it will be be 2 ohms and I don't think I should try that with my amp.
@@BostonMike68 ya you won’t want to do that. You’ll have to go series. At least your amp will like that instead. Lots of headroom too.
Very interesting video 📹! 👍 Thank you very much, Mr.!
Very useful
That was super helpful, thank you very much! 🔈🔈🔈🔈🔈👍😄
I see 10w resistor 1 is still at 50 watts how long would it last at that power level
That level of power is only going to be at very short bursts. Milliseconds. Also, I usually put a couple of resistors in parallel, essentially doubling the power handling. I’ve personally never had a resistor burn up, but if it happened they’re easy to replace.
very nice
In a first order filter, for example for a tweeter, does it matter if the attenuation by a resistor is put before or after the capacitor? Or is it the same?
It does matter because if it’s after the capacitor must be smaller for the same affect. Either can work just find though. Sometimes I put a resistor before AND after the cap to get the outcome I want.
Hi ! You make greate videos! I was wondering about impedance, that curve at 9:29, is that ok? I really dont know, so if my results look like that can I be happy? Thx!
Yup that’s fine. It’ll have some humps in it.
@@ImpulseAudioSpeakers Thank you! :)
Excellent video. One thing I wonder : do you use frd/zma files measured in free air or with drivers mounted in the enclosure ?
PS : would be a good idea to buy a mike and some absorption panels.
didierleclerc66 I measure in the box for XO design. Better results that way.
Ya I’ve improved but still not a “pro” CZcamsr. Not really trying to be either. Just doing it to help.
Can you make video start from basic to get driver files and all associated files and by using xsim to get how to make really reliable crossovers? I have bought Tyler acoustic 3 way mastering speakers which equipped with dayton RS-180-8, RS-270-8 and unnamed tweeter. I really like the very open space detail sound come out of the box, but they are bump around +5db on 3-5k and huge dip around 250-300hz so as a result the sound is so clean. I paid a lot of money to shipping and I want to keep them and work on them just because they are well constructed.
There's a lot of information to pack into one video to get from start to finish, but I will keep adding videos about how to measure and get information for XO design. Is there something specific that you're struggling with understanding?
since I played your video a bout 100 times, I got to the point choosing components. And I got .frd and .zma files off from partsexpress. Now I am going crazy putting on the graph to get flat response. Can you help me with the graph? I will pay for your service. My email thagek@gmail.com
What part are you struggling with? I'd rather help you get to a solution and learn than get paid to do it for you. But I don't mind making some suggestions either.
Thank you for your kind heart. I am struggling on first crossover point between tweeter (I picked dayton tweeter from partexpress) and RS-180-8 mid driver. I just can't make that crosspoint work.
Allen Aung ok I'll email you or you can email me at ryan at impulseaudio dot ca. I'll need you to email me the files you have and your xsim file too.
Can you upload the manufacturer specifications to design a cross over or upload real test response information?....Iam new to this.
I have a drop box account for all my driver tests. The link is in the description of each driver test video.
@@ImpulseAudioSpeakers I think I worded that wrong I'll get back to it. Good video.
Thanks I definitely would like to follow your tutorial using HiVi and Vifa drivers. Hope it will be a three way.
Vic G I do have a Vifa midrange tested and reviewed you can watch, but nothing HiVi yet. This channel is just starting so possibly hivi in the future. Watch for a test and review of the Vifa XT25 tweeter. No Vifa woofers though. I do have some cheap Peerless woofers here but they are 5.25" and wouldnt make sense in a 3 way.
hello! I want to set up a crossover that can modify a curve of a mid-woofer that I have, because at around 70 Hz or so, when I put into the enclosure that I've designed, sounds really bad... and there is little I can do with the enclosure, and I was wondering if it is possible to attenuate that frequency using the crossover... I've noticed when you modified the "mod sensitivity", the whole woofer curve dropped a few decibels, but I don't know exactly if that changes something (?)
You can do this easily with eq or moving the speakers around in the room. Basically impossible using passive crossover components. The room is likely causing a boom sound at 70hz more than the cabinet.
@@ImpulseAudioSpeakers That's what I did... adjusting the volume, or the pots of my preamplifier, and it did something to a degree, but still... at a distance of about 1.5 meters or so, that booming sound was so loud, that I had to cover my ears... So you say that its the room... I could be... the cabinets are 1100/220/300 (H/W/D in millimeters), and my poor room has 3.5 by 3.5 meters, and it's not soundproof! In a way I am glad that is the room! :)
Thank you very much!
🙏
It IS the room! Unbelievable!!! In fact, my speakers sound AMAZING! 🙂
i started on xsim a few days ago i want to make a 3 way crossover but because i have professional components, the frd and zma files weren't available i have the sica 10fe 3 cp 8Ω woofer the sica 8m 1,5cs mid and the visaton sc 10 n tweeter i'll send the pdfs too.Now i got the curves from graph tracer and edited them, with paint 3d i erased everything except the frequency and impedance charts everything works in xsim, i noticed tho that the curves of the drivers, are not aligned with the x and y axes of xsim based on the factory pdf. Is it possible to adjust the axes of xsim so that the curves appear as they do in the factory pdf?? and if so how? As you guys can see for yourself in the crossover photo i sent the frequency of each driver if you compare them to the factory pdfs does not align they start at more hz and more dbs i would really appreciate an answer cause i cannot align them.
Hello! Thanks for sharing this amazing knowledge about crossovers... and thanks for the hint with Xsim! Wonderful program! I was wondering, very few are using series crossover networks, and I don't know why!? I have built some crossovers of first or second and even thrird order, parallel vs series, and ... they sounded better on series! On the parallel versions I had to use several parts to obtain what I wanted (using Xsim, of course), but in series... I've just needed a few components, and on the Xsim it showed exactly what I wanted almost immediately! I know, of course, that if I needed to change one component it affected both drivers at the same time... it is a disadvantage! But, seriously, its sounds much better! What is the science here, anyways?? Is it the taste only? Is it the drivers? Or the room for that matter...? I don't know... I've always used a midwoofer (6.5") and a dome silk tweeter! The midwoofers were eighter with paper cones or kevlar cones and rubber surrounds! Nothing else whatsoever!
Every time when I built series crossovers, the midwoofer was on the first order, whilst the tweeter varried from first order to second order... when I used second order for the tweeter, it was Linkwitz-Reily!
They can work very well but are a pain to design. Parallel cross overs let the design mash the driver into submission without affecting the other driver. It’s a real trick getting series to work. But they certainly work just fine. I’m not sure there’s actually a sound quality benefit, but if it works for you go for it.
What is the mod delay used in the Select Driver menu? Can't you tell which parts are being calibrated or which parts are being used for speakers or which parts are being replaced?
W엉덩 I use the mod delay if I want to change the physical location of a driver or to set the Z difference between two drivers. Not much else for it.
Hi Ryan, just wondering why you didn't use a measurement of both drivers in parallel to use as the basis to set the acoustic offset?
Maz 4bz I did. I might not have shown that in this video because it was about how to use the software, but I usually do. Note that method is not always necessary.
What is that ESR value? How do I enter the correct value?
That is just the resistance of the inductor. Usually about 0.3ohm for a small inductor and 0.5 for a medium to large inductor. Some are up to 1.0ohm if they’re big air core and small gauge. Usually labelled on the inductor or you can just put a multimeter on it and measure the resistance. It’s not a critical item to get right most of the time.
Hi, thanks for the tourtorial. I would like to add the circuit block to take out a notch in my system but I can't find the circuit blocks. Did you download the circuit block function elsewhere?
I’ve been hearing circuit blocks are no longer a feature in Xsim for some reason. I didn’t have to download anything special.
If I have two bass driver mounted in a cabinet and the load is 4 ohm at the low pass filter crossover point. If I add a further two bass drivers, would this change the response for what the crossover was designed for. 4 ohm....
Dave Jones yes it will. You will change the impedance and the sensitivity. It would require reworking the XO to sound ok.
The version in the link doesn't have the Baffle pull down. The version that does is in the BetaTest folder but the Baffle pull down is greyed out and doesn't work. Is there a current accurate link to the most current fully working version? Thanks.
Greg Olsen I’m not too sure. Someone else recently asked about this. It seems the developer has pulled it maybe?
Hi Ryan
I've watched your videos about using XSim crossover design software and I think I understand how to use it, but I have a question about working backward, so to speak. In other words, let's say I don't have ZMA or FRD files, but I know the actual crossover components and their values. Is there software I can use to determine the crossover frequency, or any of the driver values of drivers that could be used? E.g.: impedance, FS Q parameters or even expected frequency response curves. Btw, I really like your youtube channel, and I always look forward to new videos. Thanks
Ed Incleve hmm, I’m not aware of that sort of software. Would be really tricky without the files. A lot depends on the frequency response where the XO point is. Sorry.
Thanks. Very informative tutorial.
Hi... Great Video... one question.... How do you account for Baffle Step Compensation inthis software?
bsl bl there’s nothing in particular you need to do. Just design the crossover to tip the woofer down in such a way as to eliminate the baffle step.
Thanks for a great video. I'm noticing that the mod delay for my woofer is making a significant difference to my frequency response and would like to put in an actual value, or even better offset my speakers when mounting in my cabinet. At which location on the speaker do I use to measure mod delay?
jpc6204 it’s easiest to measure both drivers individually and also wired in parallel, without moving the mic. Then in Xsim add the graph of them wired in parallel as an overlay. Then adjust delay until the response aligns with the parallel measurement. This will give you the proper delay. It’s fairly important to do right to get good results, but if in doubt about 25mm usually works.
@@ImpulseAudioSpeakers Got it, thanks! I also saw another video you had entitled "Life S5 | Part 3: Design Goals and Setup," which walked me through the process. You're gonna make me a master speaker builder in the coming months!
When this program starts, you'll get the speakers.When you call in two twitter and woofer, if you synthesize an RTA graph, the graph sometimes goes over the screen too much, and the dB difference between the speakers is more serious than you think.In this case, how is the setting correction year right?

W엉덩 I don’t understand the question. Maybe I haven’t had this issue before.
@@ImpulseAudioSpeakers Please let me know your e - mail address.
hello, Im building 2 way crossover with 2nd on bass and 3rd order on tweeter. crossover line is 5000hz, and the graphics of the bass speaker and tweeter overlap a bit, and in general it turns out smooth. but the blue line called the system rises at the junction
. that does it mean?
lol lol that means both the tweeter and the bass are playing in phase together so both outputs are creating more output at the XO point than the rest of the system. There will be a peak in the response that may or may not sound good. Probably best to adjust the XO a bit to flatten that peak down a bit. Depends how big it is though.
Could you please point me to the place where I can find driver files for B&W 802 S3? I used Xsim to simulate XO for B&W 802 Se using default Xsim files and got perfectly tuned XO, but I suspect that my XO far from perfect because I do not have real B&W 803 S3 files.
Fred Kleytman you are right that actual driver files will make a big difference. Unfortunately I don’t know where you could get the files for that driver. I doubt many people have measured them. Unlikely you’ll find them.
Hello, I have one question. If I don't have FRD / ZMA Data File, how can I get it? Thank you and best regards
Honestly, you have to measure the drivers like you see me do in some of my videos. You could also look for them for other drivers, but be sure the baffle size is the same. Most drivers are tested on a very large baffle which we don’t use in our homes.
Thanks i try this application but i experienced frustration our speaker has no complete specs data sheet.
Yes you do need the measurement files. Without those it will be frustrating.
@@ImpulseAudioSpeakers thank you sir. Here in the philippines they are not incline to use dividing network. We rely to ready made dividing network from online seller.
Please adjust your camera white balance.
Yes I’ve gotten better at that in my later videos. Thanks.
on my Xsim the chart isn't being updated as i make changes... how do i make the charts dynamic?
I’m not sure to be honest. Mine has always been that way.
@@ImpulseAudioSpeakers silly me, its because i didnt ground the amp
Doesn't phase line where they line up have to be at the crossover point?
If not, I've really been making thing's hard work for myself.🤦
If I’m understanding your question correctly, yes phase should align at and through the crossover region. It doesn’t actually have to, but I believe it’s the best way to design it as you get the most tweeter protection and stuff.
@@ImpulseAudioSpeakers ah, yeah that makes sense. Was just unsure if I'd just been going above and beyond to what wasn't needed but I just forcive habit. I also try to make impedance phase as flat as I can as well, although probably really not needed, certainly isn't something I hear anyone really chasing. I'm of a good understanding of impedance, but impedance phase in speakers is a job to find an explanation of how it's beneficial.🤔 Any ideas on that one? Is it something you have ever tried for any reason?
@@zefrog7482 I really don’t concern myself with impedance other than ensuring it doesn’t go too low. Especially at low frequencies for a wide band of frequencies. If it goes down to 2ohm at 8khz, or something like that, I don’t get too concerned. 3ohm from 60 to 200 hz is a problem for some amps.
how do I find the dropbox link you reference in your video for FRA files?
It should be in the description of the video.
Great video, Does this software also have the ability to simulate drivers when installed in an enclosure? and does/can it take into account front baffle size (bafflestep?) too??
It uses the measurements you provide. So if you measure in the baffle/enclosure you’ll capture the baffle step loss. I think it does have a baffle simulation feature but not too familiar with it.
@@ImpulseAudioSpeakers Cheers thanks, will be keen to give this a go
something wrong with Xsim program. can't display the popup in full no matter what screen resolution.
Hello, this tutorial is awesome! I'm trying to design a 3-way crossover for my 3-way speakers right now, with real measurements i got through REW. i was able to get a decent flat response like yours, but the overall impedance curve got awry. It changes between 3-19 ohms, with 2 major peaks and 2 minor bumps. You didnt mention much about the total impedance result, what should be our target when designing an XO? Is the combined impedance important for the performance?
klazzera Impedance definitely requires considerations, but if you're using a modern solid state amp you don't need to get too fussy. The higher the impedance the easier the load on the amp. 3 ohms isn't to bad, but its a tad low. And the curve doesn't need to be flat. John Atkins of Stereophile comments on impedance in the measurements section of that magazine and can be helpful to read the types of things he finds on different commercial speakers.
thanks for your quick reply! so let's say my amplifier is rated at 60 watts at 8 ohm, does that mean any impedance value above 8 ohms mean that my amplifier power output is less than 60 watts at those regions so i should compensate with using a higher wattage amplifier for those impedance peak regions? I'll also have a look at the magazine you mentioned
klazzera yes the output will be less than 60 watts but thats not a bad thing and it definitely doesn't need to be compensated for. It just means the speaker is more efficient at those spots and the amplifier doesn't have to output as much. It's the low impedance spots that can give your amp troubles. Think of the high impedance like a benefit.
oh okay i get it, further tweaking on the frequency response i realized there are some 0.5ohm impedance dip points have appeared, i guess i'll need to fix those first. I guess i should keep the whole impedance curve above 3-4ohms. thank you so much for your help!
Cool video, thanks! Do crossover simulation programs not take into account total sound power (e.g 30 and 60 degrees off-axis response)?? I also can't seem to load frd and zma files traced from FPGGraphTracer. I keep getting a "file load error!". Any idea?
Not sure why you’re getting the load error.
No they don’t usually show sound power (power response). Most will allow you to pan off axis and as the designer the off axis should be measured.
@@ImpulseAudioSpeakers Thanks!
Looked everywhere for Xsim, the one valid link I can find is blocked as it says it isnt secure?
It’s been a while since it was developed. Maybe it’s not offered anymore. That would be a shame. Or try the non-secure link. It’s just a buddies website. He won’t hack you if it’s his.
@@ImpulseAudioSpeakers I managed to download it thx, was looking for your video on how to download drivers, I need one for a seas excel woofer and tweeter.
I been using xover pro and bass box pro I purchased off of parts express. Has anybody else used these, are they any good? I been using them for years and really like them but have nothing to compare them to.
IowAudio Review do they let you import actual measurements of the drivers? Or just use theoretical lines?
Subscribed. Love your videos. I almost ordered 5 crossovers by Dayton sold at partsexpress, crossed at 2500hz. Basically I've gotten PSB T65 Drivers, tweeter and woofers, cabinets were destroyed by the original owner along with the crossovers. I'd really like to somehow contact you or get more help on how I could go on about designing them completely to perfection, as I can't find their data sheet anywhere at all. Thankyou :)
Rohail Butt hey glad you saved your money. Tricky situation though as you would need to measure the drivers. If you could find a spec sheet you could at least get some data files based on that.
Thankyou for your response! Well I contacted PSB and got a reply, they are not helping me either. So basically i've wasted my money and nothing will come good of it?
Rohail Butt they won't tell you what the original schematic was? Can they at least sell you new XOers? What is the damage? I wonder if they can be repaired...
Damage is that they've been thrown away :( they don't have the xovers anymore so cannot be sold. I asked.
Rohail Butt ouch. Hmm, if you can't get your money back the best thing may be to use a generic crossover temporarily and use the speaker to learn. Or maybe reuse the cabinets to start a new project that has been proven properly.
Is this software ever updated? I thought it would have a home page, but i cant find it, everything i find relates back to 2014, i'd think by now they would have made leaps and bounds of progress.
analogaudio rules it doesn’t get updated very often but did receive an update about 2 years ago. It was pretty big too.
Why would you only want 10 watts to reach the tweeter from 100 watt amp?
Nosajjao if the sensitivity of the tweeter is much higher than the woofer (which is common) then the input to the tweeter needs to be restricted using resistors. It also helps protect fragile tweeters. Big amps are mostly for the woofers.
Ryan, please advise me on the location of that CircuitBlocks file folder. It somehow disappeared from XSim program that I just installed and used for a first time tonight. Instead of that folder "CircuitBlocks" button now gets me to the folder where I've stored FRD and ZMA data. And my laptop also can't find the "CircuitBlocks" folder on a hard drive. So now I can't use any blocks. But I used one of the blocks a bit earlier just before I've loaded driver data.
I’m not sure what is happening for you. It should be along the top menu, but I’ve never had that problem. To be honest, I don’t use circuit blocks very often, even though they are useful. So maybe I am missing it too.
@@ImpulseAudioSpeakers I have figured out what had happened. When I finished working on a project last night I have decided to save it using "Save As" option. The program offered to save the file in the "CircuitBlocks" folder. But I instead have chosen my own folder elsewhere.
After that, every time I tried to use that "CircuitBlocks" button on the top menu the program would offer me to load blocks from that same folder where I saved my project. However, that folder has no any crossover blocks in it.
Then I have tried to find that folder named "CircuitBlocks" on my computer but the Basic Windows 7 could not get it. So, this morning I have asked a friend of mine and fellow speaker builder to install this program on his machine. He then opened the "CircuitBlocks" option window and told me the path to that folder on a hard drive. That was my question, Ryan (the location of the folder).
Now, that's where it can be found:
\\[Name of your computer]\Users\Public\XSim\CircuitBlocks
something wrong with the site for downloading program, have a good link?
Sorry I don’t. I think the developer of the program may have abandoned the software.

how to design active crossover any idea plz explain ?
Same as passive. Really no different other than you don’t need the impedance tests.
Is there any software like this for Mac? I don’t want the trouble of loading and leaning to use windows.
Thank you
Brian Oglow I’m not sure. I heard of a pay program a while back but not sure it’s still available. Fuzz measure I think it was called.
Hello, how do I enter the parameters of the measured speakers? Thanks
Do you mean the TS parameters? Because you don’t enter those for crossover design. That’s for box design.
@@ImpulseAudioSpeakers thank you for your answer, I would at least like to enter the necessary parameters like impedance ..
@@mikreference3a130 you need to edit the driver and add zma or frd files.
@ Impulse Audio..... Whats the difference between a series and shunt notch filter? I was looking at trying to reduce a 7db peak at 15KHz of a tweeter. Also, What do you do to raise a dip in the frequency response of the system?
bsl bl a series botch is a weird name because it’s an inductor, capacitor, and resistor all in parallel, but that set of components is in series with the driver. A shunt (or parallel) notch is the opposite. In parallel with the driver but the parts are all in series. The series notch would be best for a 15khz peak but shunt could potentially work there. Shunt notches can really lower impedance if you’re aggressive and in the driver’s bandwidth.
Dips are really hard to fill passively and depends on where and how. Possible to fill it by using the tweeter padding and filter. Certain things can work. Dips are less of a problem than peaks, and some dips shouldn’t be filled. Such as those caused by diffraction.
Thanks Ryan. I guess the name series notch is because the notch is in series with the driver and the shunt notch is so called because it is in parallel to the driver.
So, I notice that to get the peak down, I need to go to about 60 to 70 ohm resistor value in the series notch. Is that something normal?
bsl bl no that’s not normal. Have you adjusted the inductor and cap to try and widen out the Q factor? 7 dB at 15khz is somewhat odd. What driver is this and how was it measured? If the data is good I would keep working at it and see what you can do with it.
@@ImpulseAudioSpeakers .... The driver is the Dayton ND25TA-4. I am using it with the ND90-8.
good tutorial ryan , i learn so much from you . but its too fast expanation for me .
ozy prima sorry about the speed. As you do more and more work with Xsim it will become clearer.
Impulse Audio how to read impendance correctly in curve ? Is the best as flat as or how should it be ?
ozy prima doesn’t need to be flat. There isn’t really much need to focus on the impedance curve other than to make sure impedance doesn’t go too low and cause problems for your amplifier.
@@ImpulseAudioSpeakers its means just keep focus on phase and freq response ?
ozy prima well yes but do make sure impedance doesn’t go below say 2ohms. At least. 4 ohms is better.
great and informative video!
would you happen to know any program that i could extract/copy/trace the FRD and ZMA files with based on driver SPL graphs? i have Visaton drivers but i can't find any data files for them online..i read about a program called SPL Copy or smth but its not available anymore..atm i'm using Boxsim for crossover design but it's kind of confusing for a newbie like me
hope you can help :)
Martin Ahven the only one I'm aware of is SPL trace but I think that's probably the one you're thinking of. If it's not available anymore I'm not sure what to say. I know another channel called 123Toid has done a video about it, so you could check there. You can also manually do it but that would take forever.
So I have been informed that fprawn's FPTrace is the new program to use. It's apparently quite good, though I haven't tried it. Hopefully that helps.
@Martin Ahven: I tried FPGraphTracer but it sometimes recognises the wrong lines depending on where you click. You might have to compile one file from parts of several files.
If you use Visaton drivers you should definitely play around with BoxSim. If you speak German watch the BoxSim tutorial by "Leo Lautsprecher". It's really good! Maybe also watch my tutorial about crossover design where I used BoxSim but don't explain much: czcams.com/video/5Kvl0iBQ0L0/video.html.
great tutorial, but I really struggle building a nice and simple crossover for the Dayton nd105-4 4 and the Dayton ND25TA-4 (50W per channel) , can anyone help me?
Of course he won’t, don’t hold your breath.
Does it work on horn speakers?
Yes no problem.
Nice one. Xsim is ok but you really should try vituixcad. It is just a lot better program and also free.
maped345 a lot of people have recommended it, but I haven’t found an advantage. I like software that is simple and to the point. Which is part of why HolmImpulse is actually my favourite measurement software even though it’s not popular. Xsim has a lot of power built into it, but the core of it is very straightforward.
i got frd and zma files from parts express. which frd file do i use it came with 4 different files
toad cut I’m not sure. I’ve never used their files. There should be 2 files for each driver. 1 frd and 1 zma file each. So 4 total kind of makes sense.
Can the software account for baffle step?
Can you recommend any cheap microphones to go with xsim to design a crossover?
Max B. Simonsen I think the minidsp umik is pretty cheap at around $100, and is perfect for the job. But if that’s pushing the budget try google Panasonic WM61 capsule. I might not have that quite right, but it’s a DIY mic you can build for about $5. Not bad either. You’ll want to upgrade in the future but worth using it to learn.
how about active crossovers? any software for that ?
From where to download XSim safely? Please give some link or info.
Oh man I don’t know anymore. I assume a google search would find it. Bill Waslo was the creator so maybe his site.
@@ImpulseAudioSpeakers Thanks, I've found the link on diyAudio 😀
Hellow Ryan! I hope u r good. I got a confusión about pre-design crossovers. As we know, there are lots of crossover labels in the market. All of them with a specific cut of freq and components. let's use, for instance, the Dayton XO3W 375/3k. If we are looking for those specific cuts, what's gonna happen is that... we're going to buy that crossover because it supposed that is gonna work, but as soon as when designing our crossover for our system in Xsim and we put those values of those components of that pre-design crossover to see how it going to behave and for achieving those cuts entering the FRDs files, they change a lot. Those values are not the same anymore. My confusion is...when that label built that crossover, they built it base on what? Because and,-correct me if I wrong but,- I don't think they come with a manual saying: "oh, by the way, this crossover works perfectly just with eminence speakers oooorrrr whatever". I don't know if u get me, bro, ooorr maybe I'm missing something or I'm still ignorant of something. Can u help me with this? or can u make a video showing whether if it is true or false or something educational about this the way u did in the video on "whaty not to use online crossover calculators?" Thanks, Ryan.
Joseph Anselmo you are correct. Those things are junk. And I actually did make a video sort of about it. It's called something like "why to NOT use online crossover calculators". Those prebuilt crossovers are based on perfect flat 8ohm loads without any deviation from flat and assume phase is perfect. They never work.
What that hell! I had that little bit that those things are junk.
Are there any profiles for Beyma speakers?
andythewooferguy I dont have any Beyma drivers to be honest. I have Eminence and Celestion from the PA world that I will eventually review and post the measurements. But nothing Beyma. Is there a specific model driver you are interested in? I could see about eventually getting one or two of them to try if I have a need.
Impulse Audio 15G40, 8G40 and the CP21/F. Do your make these profiles yourself?
andythewooferguy Yes. If you look at my other videos I have 3 or 4 driver reviews. Just getting started. There will be many more.
Next is the Motus UH205PW1 and then the Denovo Magnum 12. Ill look up those Beyma drivers and see if I can find a use for any of them.
those are first order filters no?
H LW no, there’s two poles there. But you can adjust however you like in Xsim.
@@ImpulseAudioSpeakers I was overlooking the driver itself! Cheers :)
I created frd filefrom curve and icant load it. It says File load error, followed with name of file. I traced curves in FPGraph tracer. When i compared frd which came with app with mine i noticed i have only two columns of numbers but these frd files have three columns with numbers?? I am confused
Zox Wolf it needs three columns. Frequency amplitude and phase. You can even just add 0 for phase on the whole thing. But you’ll need to extract minimum phase in that case. I show how to extract minimum phase in my Life S5 series, about part 4 or 5.
@@ImpulseAudioSpeakers Thanx mate, I manage to make frd and zma file but as you said phase is 0.
I will check your other videos. How much accurate is this? I noticed that i need to adjust scaling (vertical center and vertical value) on right windows othervise i cant see my frequency and impedance curves. I traced original dynaudio graphs in corel and than in FPG tracer.
I am planing to get DaytonAudio OmniMic V2 with software. Do you think it will export FRD and ZMA files as it should.I am still confused bout using this Xsim :(
Cheers mate
Zox Wolf without phase it’s not accurate. But you can extract minimum phase which is accurate to a point. Difficult to explain. Omnimic or any mic like that will give you the frd files. Zma files are different and require an impedance tester.
All this can be quite confusing. I keep planning to make a video showing the process from beginning to end but it’ll be quite a bit of work.
@@ImpulseAudioSpeakers Thanx for your explanation. I intend to get DATS V and OmniMic V2 from Dayton Audio :)
I will closely monitor your channel for tutorials ..

John Johnson ya he’s kind of gone into retirement. The free version is the only version. When he made it I asked him about support and stuff. He said he did not want people contacting him but did want to offer it free. I think he didn’t want to have to field all the support emails. If he knew people wanted to give him money he may have made a website 😆
Great Tutorial but how do i add driver files from Vifa and SB acoustics drivers i already Have
Cary Phillips you would either need to measure them, which is another entire subject on how to do that, or somehow get the files from another source. There is a program called SPL trace that creates frd and zma files from the manufacturers spec sheet.
What sb and vifa drivers do you have? I will be measuring the sb13pfc25-04 next and also the vifa XT25SC90-04. I may also have others.

Cary Phillips of those I only have the Vifa XT25SC90-04 and will be testing it next in fact. I currently have it in a box ready to go. It's going in my latest video and should have test results within a week. You'll be able to download the files and try them in xsim to see what could potentially work for you.
I do have the SB29RDCN-0004 but it is slightly different being the neo version. Could get a test of those though, if it would be helpful. It would have to wait though.

@@ImpulseAudioSpeakers I meant the location of the drivers on baffle. For example, if I position the tweeter 60 mm to the left or higher or lower. How does XSim understand what driver placement I made in my project?
Vladimir P you should see my follow up video that shows the baffle functions of Xsim. But you really don’t need it. Always keep the tweeter as close to the mid or woofer as possible.
Boxsim??? Why not use the best???
What’s wrong with Xsim? I don’t think I’ve tried Boxsim, but I don’t believe it does XO simulation.
