how can I get in contact with you..?
@@palledrengens I don't think it's you because it doesn't work for me either and I'm in Indiana.

For Mac Users (this may have been said already) I finally found a way to run WinISD. Wine and WinBottler are free programs that have been recommenced to run WinISD without the hassle of virtual machines, bootcamp, parallels, etc. But for me, both of those program wouldn't run properly but simply not opening, or quitting/crashing when trying to load WinISD under advance options, respectively. Nearly giving up, I found Wine-Stable (Wine-Stable 7 the most recent version, but Wine-Stable 5 is what worked for me. I could be wrong, but during install I selected both 32 bit and 64 bit as an option. After installing Wine-Stable 5, I am finally able to run WinISD on my Macbook Pro, without having to pay for a windows subscription. I hope this helps anyone with a Mac!
Awesome!
Your content is so indredibly helpful to DIY beginners. I'm binging your stuff at 2 a.m. taking notes.
Glad to help!
4 AM here
Another 4am nigh owl here haha
I have started modding my speakers, now I want to build my own enclosures. I Love boxes that really let the LFE pump out.
Loving your video's, 3rd one in a row. Great work! WinISD is something I'm still learning myself, people like you and some others have been cool enough to break it down a little more for me. Appreciated!
Glad to help!
You provided me so much information thank you. I have a prefab tswx300a and i added an external port with pvc pipe😂 i know its a frankenstein build but i can hit lower frequency now its a new box tuned to 28hz ( yes its a long port ). I never took the time to thank you for all your amazing work and your knowledge sharing . Salute from Paris. I might start upload my bass head journey😅
I've been using winisd for quite some time. And I know all the points you said. But still I love to watch this video often 😂😂😂😂😂 ur explanation is energetic and engaging !!!! Great job !!! 👍👍👍
Glad you enjoyed!
Really appreciate the information on this subject and more.I have learned a lot from your videos and cleared up all the noise from friends sending me in every direction except the correct one.Math doesn't lie. Thanks
Glad to help! Maybe share some videos with those friends that need some guidance?
Awesomely informational. Thank you for all the great videos.
Thanks for watching!
You’re amazing! Enjoyable to watch and very helpful!
Glad to help!
Well explained. i had this sofware and deleted it now i going to re install i been searching months for info like this i learned everything in this video thanks my speaker is new on the market so i had a very hard time getting the correct box
Glad you enjoyed it!
Very useful video for the new version. Thank you.
You are welcome!
Glad to know that you are also a Windows User like mine ❤❤❤
From what I can tell this software is not available for a Mac.
Note on T/S parameters that I believe you have covered in another video but did not mention here; the mighty DATS! I love mine and for folks who play around with older or oddball subs the DATS is great for getting a set of T/S parameters to base your build on. Thanks for the great video!
DATS is a great tool!
You can build your own DATS for $30
Thanks for your videos! Using WINISD I learned that my particular subwoofer will play louder in all low bass frequencies in a smaller(1cu ft) sealed enclosure than in a 1.5cu ft. ported one. The TS of my sub indicated that it leans more towards a sealed sub than ported so this makes sense. The math doesn't lie as long as all the subwoofer information is properly filled in! Also I had port velocities up to 30m/s at tuning with the ported which isn't terrible but definitely not optimal. I just wish I could share my graphs.
That's the cool part about modeling enclosures with software, takes a lot of the guess work out of it.
hmm that's weird what subwoofer is it?
Interesting, I designed a 3 GHz RF cavity with tuning ports called re entrant cavities back in the 1990s. I used it for an electron positron accelerator at SLAC while I was at Stanford back in the day. I used it to smash sub atomic particles while you smash air molecules!
Science is fun.
Using this to design a box for 2 epique 7" dvc woofers for my room right now!
Been looking for this video 📹 thank you 😊
Glad it was useful!
It can def be a challenge. I had the older version on my other laptop. Downloaded this version n I believe it to be a little less complicated than the older version
I appreciate all the content you put out for us. (yes I know this was put up long ago) You make inputting the Thiele Small parameters look so easy. I'm not sure if I'm doing something wrong or if I don't have all the necessary info. After several attempts I'm still getting the dreaded red bar when trying to load the sub. Looks like its back to old school paper and pencil work for me.
When you enter the parameters pause for a second, click into a different field, and it will auto-calculate.
@@DIYAudioGuy thank you. I’ll give that another try when I get home.
I had the same issue with the latest version on widows 10. I ended up installing the older Alpha Pro 5.0 version. Rarely have issues other than manufacturers listing conflicting values in which case I only enter the bare minimum. I actually like the older version GUI better.
You make great informative videos
I appreciate that!
Hello @DIYAudiGuy, start off by saying I love and enjoy your videos! I have learned a lot by watching you and has taken my box designing to the next level. Made me feel so comfortable, I started taking on building for people. Question, I have a guy that has Nemesis Audio na12e v.3 subs, and I cannot find all parameters to get a green flag from WINISD. Is there a video on this, or a way around it? Any help would be much appreciated.
I dig your channel, I'm glad I subbed. Have you ever made a video on how to build a box with bass radiators ?
I am glad you subbed! One of my first builds was a PR, I have been tinkering with them off an on. Here is an experiment that I tried: czcams.com/video/6AShG7ozRsI/video.html
It failed because the PR's came unglued.
THis was version 2.0, it was MUCH better. Ended up being tuned to 22HZ. That little 10 was killing those lows.

@@DIYAudioGuy Thanks I'm going to watch it now
Hahaha... Im literally struggling with this since 2 days now, and here is Your video. :D
I hope the video helped!
Thanks for the video!
You're welcome!
Your subsonic filter can greatly reduce air velocity which allows the use of a smaller port. I set my subsonic filter at the subs f3, but some also recommend setting at 2-3Hz below tuning, or one half octave below tuning.
That's a good point. I've got a video on setting an account infrasonic filter, I never thought about the impact the filter would have on port noise. But if you're cutting the signal you're going to be cutting the port noise as well. czcams.com/video/iWRoIho7A7c/video.html
A few hz below tuning is still cutting audible frequencies , a ported enclosure still plays below tuning , my box is tuned at 33hz but I still get audible notes at 28hz no way I would cut it at 32 or 31hz......imhave mine set at about 20-22hz that's much more reasonable
@7 Logik Well it also depends on the slope (6db, 12db, 24db, etc.) applied power, type of subs, enclosure size, and type of music you're playing (Rock, Hip Hop, Rebassed, etc.). The crossover filter doesn't just abruptly cut off frequencies, but it rolls them off at a given rate depending on the slope. So with a 33Hz tuning if the filter was set at 30Hz with a 12dB slope you would still be able to play 28Hz with no problem. The lowest recommended is 1/2 octave below tuning which would be 24.75Hz at 33Hz tuned.

Love your channel
Thanks!
I'm so glad I found your channel. How did I not know about it sooner? Lots of technical stuff which I love. One question I have or would like to see a demonstration of is dampening or dampening factor. How ohm load effects it and spl/SQ and such.
I am not an expert on amplifiers, but from what I gathere damping factor is a way to express how well an amplifier controls the cone movement. It's one of those things that's important up to a point. Like everything else with audio there are diminishing returns.
@@DIYAudioGuy appreciate the reply. Its one of those im not even sure if or how they can measure it. Strage thing I've noticed when playing with the meter is that seems good damping seems more efficient with spl. Ya you can gain a db going to half ohm or whatever. But at the cost of 2x the amperage draw and sloppy cone control. but also not the case always.
@@sittdogg there's a device called an audio precision, the big manufacturers should all have access to one.
I always try to express the importance of high damping factor when playing low frequencies it’s basically the amplifiers ability to control the incoming eddy currents
Winisd is great WHEN you can get the parameters correct in the correct order! That is always the frustrating part for me.Or when all the data is entered and winisd says it's wrong.But when it works, it is awesome!!
I find that often times it works even if the driver parameters aren't right.
@@DIYAudioGuy Maybe I have a real old version. It flat out will not let me continue when its is not all 100% correct.Ill delete and re-install and try that. Really is a insane FREE program!
@@jondoe6618
I think there is an article on Home Theater Shack that tells you how (in terms of the order) that you enter the parameters in order to get it to work. Tried everything but this article worked for me Finally.
@@drrckhamilton I watch toids diy audio video on how he does it. That has been the only way I have done it successfully.
I need help with a slot ported box sub up port back in a 2003 chevy tahoe for two 15s
Thanks DIY guy.
No problem!
Looks like a cool program! Never tried it but I'm gonna have to get a computer so I can use something like this for designing speakers! (Only internet access I have rn is my phone which I'm writing this comment on.)
The good news is that it's a very old program so you don't need a new or fast computer. As long as you're running Windows it'll work. Avoid things like Chromebooks.
Aaaand, you've got a new subscriber.
Useful for higher end subwoofers as the lower end manufacturers dont give you any soec details such as this.
Yes, true
hello good night, great video. I would like to know if the calculation that winisd makes of the box, if the space that the speaker and the duct occupies is already included. Thanks
Nope, WINISD is going to give you the net airspace not the gross. So you have to add back in the port, any bracing, and the speaker itself.
Thank you
You're welcome
LoudSpeakerDatabase is also a fantastic source for T/S Parameters (as it already has pre-populated files!), but it's user contributed so there's a bit of lag between new drivers and files being available.
I will have to check that out!
@@DIYAudioGuy It's great for people like me who always mess up the "order on entering the specs" or who struggle to find specs for certain drivers. It's sooo helpful when it's already there and all I have to do is click the "WinISD" link and download the file.
I look forward to hearing your thoughts on it.
Thank You so much for telling I spent 30 min entering the parameters it worked in the end but I'll still use LSD. Should have read this comment before doing lol
Hmm I tried using the LoudSpeakerDatabase driver and WINISD shows the red sign so it won't work in my case
@@ashyouknow7420 Ahh, that sucks. I wonder what parameter didn't pass integrity checks.
you are the best!!!!!!!!
You are far to kind.
WinISD accepted Hifonics Zeus ZXS-15D2 Xmax 26mm peak, but not 14mm linear Xmax. When i did use xlim 26mm and xmax 14 then the integrity check was all good. Its like math classes i hated :D
Love your videos! So easy to digest the information. Do you still help Patreon members with box designs? Looking for a second opinion on a design I received. Thanks!
Yep.
Plz make video on curve dual bass .how set the angle of speaker.wich things we have to notice for this
If you would, could you make a video explaining the differences between the older versions of winisd vs the new one (one youre using). I have only ever run an older version (0.44) and it is a completely different than the new one you just showed. Part of the reason being that the new one's auto fill for the T/S parameters screws up sometimes. Manufacturer will have one spec one way and winisd will say its wrong. Other than that I didnt know the new version has an excursion chart which I desperately wanted after using Hornresp (also another program you should touch on).
I need to give Hornresp a try for sure!
since 2003.. exelent small software, recommended.
yep, good stuff
Great video!
When entering the watts, do I use 80% of RMS? When I enter 75% of RMS my cone excursion is within limits but outside the limits at 80% of RMS. I am thinking I should be fine but what say you?
great video .......i was looking at the crescendo forte 15 or 18 inch subwoofer....could these be tuned to 20 or 25 hz ...?..i would like to use them in hometheater.....thanks
I'm not familiar with those drivers. Other than just sticking the parameters in WinISD there's no real way to know.
Hello! Query, the liters of the box that the software indicates in Item "BOX" are net internal liters or do we have to discount reinforcements, displacements of the sub, port, etc?
Greetings! Thank you very much for the video
Net internal. You will need to account for all of those things.
:) very nice
Thanks!
Thank you so much! Your content is super great. I'm having a problem getting "green" with my entry level subs (massive audio TKO 124) Do you offer plans for boxes? If so, how can I get you my info so we can move forward?
I have a pair of them sitting beside me. Hope to have a box plan and video out by the end of the month.
I was having terrible time passing the integrity check. Another video indicated there is certain order Winisd likes the TS parameters input. DD or SD, RE, QES, QMS, VAS, FS, XMax. I followed that, taking note which system of measurement the data was in, vs which system was default in Winisd. TA DA! Now it's green. Now
Awesome! I might have to test that out the next time I have trouble with the driver that does not pass the integrity check.
Please yes video on ts
Hi, does winisd compute the port wolume with the box/chamber volume you input or do we have to offset the port volume from the actual box, thus adding more volume to the box to compensate?
Yes, you have to add volume to compensate. WinISD gives you the NET airspace. After you account for bracing, the drivers, and the port you end up with gross airspace.
good day . I am writing you from turkey. What do you think the bandpass box dimensions for alpine swr12d4 should be? Thank you from now
when putting in the box size do i put in the gross internal volume or the internal volume after port, bracing and speaker displacement
The internal volume after port, bracing, and speaker displacement. In other words the net volume.
Question: would the direction of the woofer make a big difference in a design such as the one seen at the end?
Nope
Ah yes... WinISD... the place I spend too much time in...
You and me both!!!
Are their any books on speaker building that you can recommend.
Hey I've got a question about winisd.
I've been designing and comparing boxes for my next trunk build and I'm a bit confused.
Does/can winisd account for port placement?
There's a big difference in port+subs facing forwards compared to only one or the other facing forwards when squeezing two 15s into a trunk.
As I understand it the air pressure/sound wave coming from your port will synchronize or become in phase with the pressure/wave coming from the front of your driver and give you a bass boost.
Is there a way to know or graph when these waves become In and out of phase?
Does this effect still take place when your port is not facing the same direction as your subs, would it change the frequency at which the waves become in phase?
WinISD assumes that you are in a very large room and it does not provide any information about port location. The box size is net, meaning it does not take into account port displacement.
After my $3000 JL e-110 failed, I`m looking at alternatives, I still have a good driver and enclosure, this may be one way I can fix the lack of bass in my system.
I hope it works!
I designed a box to 25Hz but to get the port noise down I selected the option to use 2 ports. Winisd says the ports need to be 69cm long, does this mean I need 2x 69cm long ports or is it 2x35cm ports? The length of the port doesnt change in Winisd based on the number of ports used so I dont know if I need the total length of all the ports combined to be what Winisd recommends or if they all need to be the full 69cm length.
dear audioguy,
can u do a correlation video regarding
vented boxes: correlation between transmissionline;bassreflex;horn
cuz port length does in fact matter due to the resonace fq
but in a non linear but expo port
aka horn how do i calculate that
eg. big W bin is combo port with horn
I don't really know enough about horns and transmission lines to do that.
Is woofer displacement and port displacement also included when determining box size ?
Winisd does not account for that.
I have a pair of old school stroker 18ds. It turns red when I load the t/s parameters.I am not sure what I need to do to continue.
Thanks for your help
Other than just going through it kind of slowly and giving it a chance to auto calculate there's not much you can do. Fortunately it seems like the software can operate when the parameter integrity check fails.
When you are looking at the different volumes/tuning frequencies, how are you making that adjustment without typing a number into the boxes? Are you doing a mouse scroll or using arrow keys? Starting around 7:19
You can adjust the box volume by clicking on the picture of the box and moving them mouse, or put your cursor in the input boxes and then use the arrow keys.
@@DIYAudioGuy Awesome, that's a great tip to know!
Great work. Out of curiosity how much do you charge to design boxes please

Hello im struggeling to get the right slot port dimentions for my beyma 12LX60V2 do you have any suggestions to calculate this(not winISD)... Thanks...
Is the rear port the same as a front port? Because for me the winisd Works only for the rear but i want a front or from the Side. So can i use the same measurements?
The box volume in winisd tells the net internal volume (gross volume minus the woofer displacement, port displacement and any space occupied by bracing) or does it tell the gross volume ?
Net, so you will need to add airspace to account for all those things.
does winisd pro calculate in the port and driver displacement when showing the graph line? say i want a box at 2.8 after displacement. do i add in the displacement when i put in the box size in winisd. or just the end volume?
Unfortunately it does not. You have to account for the driver, the port, and any internal bracing. I typically do the math on a spreadsheet.
Hi ... Please make a video on adding room gain and parametric EQ filters in winisd. Both for sealed and ported simulations. And even after adding filters cone excurtion should be in limits.
Not a bad idea!
@@DIYAudioGuy in some cases I saw that just after adding room gain filter, cone excurtion went up crazy 😂😂 !!!!
I dont think that happens in real world. I mean, cone excurtion may not behave completely different when the sub is in an open space Vs closed room.
Or winisd is estimating wrong. Need to investigate further...
🔥🔥🔥🔥
😎
thank you, please I have a 30w, 8ohm speaker. that's the only 2 data I read on the emant. how I can calculate the air of my box (speaker) to be made using winISD?
You'll need to find a way to measure the TS parameters, the date and audio dats is the way to go. You can pick one up from parts express. If you use my discount code diy5 they will cut you a little price break.
Without that information you are just guessing. May as well just throw it in a half cubic foot box to into about 40 hertz.
So you even go below resonance frequency to tune box low? Is that efficient?
When you tune it lower the peak SPL will go down. There is a trade-off between efficiency and low frequency extension for a new given box size.czcams.com/video/A9oVxddE2GA/video.html
I have a quick question I'm hoping you can help with. When adjusting my port size as a sphere, it won't let me adjust the length, just the diameter. The length is in gray and won't let me click it. If I change to a vent, I can adjust both sizes with no issue. Any ideas would be much appreciated.
Have any suggestions for a port tuning for rock/metal? Or think sealed might be the best way to go?
The conventional wisdom is to tune a bit higher or go with the sealed enclosure if you like that kind of music. My personal preferences to tune for a flat frequency response and a low f3, that way it sounds good no matter what music you have to be playing at the moment. But that's just me.
@@DIYAudioGuy Right on! Iv'e got a rockford T216, and been scratching my head on where to even start. Your videos are helping point me in the right direction though!
Does it matter where we put the vent on the box? That is, a foot above the bottom in the middle of the back panel? A few inches from the bottom?
Thanks. Great videos.
It should not matter
@@DIYAudioGuy thanks man. So basically programs like WINisd have made it so almost anyone can make a great sounding vented box?
The most Important things to look at are port velocity, driver excursion and to have a smooth response?
Thanks again
I tried to follow along with an Alpine SWS-12D2 but the volume never gets auto populated and no response graph shows up. :( I am sure it is because I can't find all the fields required. Ah, if I edit the driver in the project and set Vas it graphs for me, not sure why it doesn;t bring the Vas from the driver I created.
This seems much more difficult to use than bassbox pro granted I have never used bassbox pro for much so IDK if they are similar in functionaliity.
Hey DIY Audio Guy, I need help! A buddy of mine works at Kipsch and he gave me a beefy 15" prototype. He didn't have the parameters on hand, but I have the DATs v3 so I wasn't that concerned. I entered everything in WinISD, no issues, but is there an ideal frequency that you tune a home theater box to? WinISD popped out a tuning frequency of 18 hrtz in a box size of 5.3 cbft. That seems awfully low to tune a box to. I've done this with a few other subs, but they were each tuned to 24 and 25 hrtz, but most videos I've watched on port tuning, and WinISD, most people seem to be setting their frequency in the 30's. I was wondering if you had any advice on what you would tune a 15" to. I understand it depends on the bass curve and all that, but you surely have an opinion on what you'd tune your home theater subwoofers to. Ok, don't hold back, hit me with both barrels,...lol.
For home theater, I like to tune the enclosure as flat as possible with as much low end extension as I can get while still keeping it flat. That typically means a very low tuning frequency and a very big box.
I use the .44 version it doesn’t argue parameters
That is correct.
What’s the difference between the rear and front air velocity?
Also what’s the x max for the audiopipe bdc4-12? It’s listed @17mm but also says 50mm pk pk. I entered 17mm in winisd.
Rear port is a standard ported box. Front port is for a 4th order bandpass. With a 6th order bandpass you will use both.
Go with 17mm
I have drivers from Parts Express and Madisound. Both sites have volume suggestions and the F3 for sealed and ported boxes. Is this good or I should see what winisd comes up with? You say "play around till you get what you like for music you listen to". A video explaining the green line in relation to sound would be awesome!
Both of those sites typically use bass box pro and design for high fidelity. I typically means that they're shooting for a flat response with a lot of low end extension. Those designs will do a good job getting low, but they're not going to be very efficient.
@@DIYAudioGuy Thanks for that. My first project is a 2.1 with Silverflute woofers, Dayton Audio silk dome tweeters, and a Peerless 8 inch sub. The goal is rich and warm, with nice bass but not window rattling. I'm about to start loading into winisd. I'm most curious about porting or sealing the mid boxes, since I have a sub for the heavy lifting that will most likely be ported
@@keithmarlowe5569 probably no need to port the silver flutes.
why is there no option for a series tuned quasi 6th! man ive been trying to find a program to model this box for days now
Does the winisd box volume for a vented box include the port displacement?
Nope, it just provides the gross air volume, not the net.
Do you sell custom box plans?
How do i decide the box tuning freq. I want a sub going low and not lossing those dbs. My sub has a fs of 35hz. So how do i decide how much to go low in box tuning. What parameters should i look for in win isd ?
Once you have it in WinISD you just model it. 35 is a good place to start for a car. Tune it higher if you want it louder, lower if you want it lower.
Is there any reason you don’t do a 1” slot instead of 2”? I’m seeing length cut in half when I do that. Messing around w winisd, the changes I make seem counter intuitive, or too good to be true for my application
As long as you keep an eye on the port velocity, that will be fine.
Do i need a high pass at ~25 hz before my subwoofer? Is it ok if my amplifier simply has a Infrafilter included and then those frequency wont even come to the subwoofer? Also does it make sense to filter those frequencies before they come into the amplifier in the first place? At the moment my diy subwoofer doesnt have that filter but my amp does, im wondering if i should be worried.
If your amp has an infrasonic filter (some call it a subsonic filter,it is just a high pass that keeps the lowest frequencies out of your sub) then you don't need any other infrasonic filter. I prefer to use the crossovers in my DSP because it is easier to adjust.
@@DIYAudioGuy Thanks for the respond! Then i just keep plain cable between my amp and my subwoofer. (quite a big system though, 2x 18'' RCF speakers on rated ~800 RMS Watts.)
I’m new to the winisd, watched your video and went trough the sssteps needed to create the profile and box design . Now how do I get that to paper. I’m a construction worker so I know how to build the box itself but how do I apply the program to paper ? Please help .
Convert to cuin by multiplying by 1728 (say 2 cuft * 1728 = 3456 cuin). Then pick to dimensions (ie. 12" tall and 24" wide) Multiply those together (288). Then divide (3456/288) to get the depth (12). Hope that helps.
So, Im thinking of building a small Cube Box for a 6 1/2" Woofer with two matching Passive Radiators. Does WinISD have a calc for this or is there some kind of work around?
Yes, WinISD will do that.
@@DIYAudioGuy Did the DL anyway and found it. Thanks for your Reply.
So is System input power under the Signal tab gonna be the peak or RMS of our amp?
RMS, always use RMS. (czcams.com/video/NuO9b1fYisY/video.html)
I typically use 80% of RMS since you lose some power due to box rise and power factor.
@@DIYAudioGuy I was gettin worried for a minute. I entered 80% of peak it was far past X-Max around 57hz. At 80% RMS its right at X-max, which is 7mm for my sub. Thanks!
Does the folded port (that you have shown 10:15) have so-called "organ pipe" resonance? And what determines a frequency of such resonance, entire length of the port or lengths of it's sections?
All ports have that issue -- it is usually not something to worry about with a subwoofer. If you were designing a bookshelf speaker it would matter a lot more.
@@DIYAudioGuy Thank you. In my case it matters becase I am planning to run woofers up to 200-225 Hz. But even minimal size port gets an least 21" long.
I have a critical mass UL 12 I want to build a ported box for but I can't even find half of the parameters needed. Would it still be possible to use WINISD to make a box for it?
Possibly, not all of the parameters are needed and some of them will auto calculate.
When you say flare the port end, do you mean just simply rounding off the port ends with sandpaper or router bit, or are you talking about using aero ports?
I was specifically referring to arero ports. But I have found that rounding off the port with a router bit is very effective at cutting down port noise.
Hi @DIY Audio Guy
Please can you assist me, I'm trying plug in a earthquake dbxi 15d 4 ohm sub into winisd but the manual I got don't have enough information especially for the electro-mechanical parameters and I keep hitting red . Any tips that could help me please. Much appreciated 🙏.
Go slower, give the software a second to auto-calculate the unknowns.
How’s the Bass Van going?

Hello for me my driver failed the integrety test, but also all the drivers that are already loaded in the program, what can i do? I have a Beyma 12LX60V2 driver...
I know you can change the port area to change the port velocity, but for spl purposes does winsisd calculate the db when you change the port size? Will the box get louder with more velocity or will it restrict output, how do you know what the port area should be for max spl? If you make the port bigger will it get louder? If so, how big is too big? And vise versa for a smaller port.
Unfortunately, it does not show the impact of port cross-section on SPL.
@@DIYAudioGuy is there a program that will account for this? Or is there a way to calculate this?
@@charlesreedy9330 none that I'm aware of, there are some rules of thumb that say when the port velocity gets too high, you'll get compression and it will cut your SPL. I don't remember the numbers off the top of my head, but it's well above the standards for sound quality, around 17 m/s Port velocity. Something like three or four times that.
Getting a really big number on an SPL meter is often times a matter of trial and error plus a ton of power and cone area.
Qts and Fs has een close relation, do you want higher Qts, Fs get,s higher and vica versa, so choosing wise for low bass is needed, I have visatons wsp26s these has fs 19 hz and Qts of 0.38 very nice for bass.
That is why I like WINISD, I don't have to worry about that. Just plug in the parameters and see how it works.
@@DIYAudioGuy I do use diyaudio hornresp, but winisd is quite oke, nice to use the gliders for the fine tuning. I had to learn to put in drivers in winisd, it is a little tricky.
Please HELP anyone! I've built myself a sealed subwoofer that has an internal volume of 20 liters (2.5 cm thick, 32 cm wide, 30cm tall and 36 cm length, all external measurements).
I've used the Ground Zero GZIW 200 driver (8") , and for this driver the manufacturer actually recommends a 17 liter vented enclosure with 1 single port ( 7cm , 2.76" wide, 24cm, 9.45" long).
It being sealed sounds great, especially since it's in use in a quite small room, thucked under my desk , but i'm curious about converting this box to a ported one and thus increase the output.
I've been playing in WinISD, tried to figure out what tune frequency i'd want (listening mostly to music) so i "decided" on a 30 hz, but i don't get it based on that ISD reports back, just what specs should this port have.
I chose a round shaped port which i'm going to 3d print, but for a 10.2 cm port (which i'd find right considering the size of the box), it said 128.36 cm long, that's 3 times the length of the actual box. Also, 1st port resonance is 133, 88, is that good, bad, unknown? Could i also make multiple ports in order to cut down on the required length? What do i do?
Thanks, i love subwoofers and audio generally speaking, and i'm also into DIY wherever i can, but getting the basics here doesn't seem that straight forward unfortunately.. :(
Can you still use Win isd with only the thiele/small parameters details. Because my subwoofer specs don’t even show any details for anything below that section, not even xmax? (Zeroflex EVO-12)
Yes.
I have another possibly silly question. If the auto fill parameter in blue is drastically different than what the manufacturer posts, do you change it or leave it with the auto filled calculation?
Leave it, but double check everything to make sure you've got the units correct. Some of them are metric. Some of them are not.
@@DIYAudioGuy Awesome will do. Thanks again.
Was wondering the same thing
I tried working with this application. Everything went fine with plugging in the parameters. But then when I opened the project and went to modify the volume of the box, I got an error “invalid floating point operation. Press ok to continue and risk data corruption or cancel.” I clicked ok either way but the graph disappears and I can’t do nothing else on the application. I already tried updating my drivers, but to no avail. I’m running windows 11 pro i7… is there some special processor I need or???
