I'm so afraid to measure my speaker's response in my room. Once I start seeing Nulls, that will just open up a deep rabbit hole I don't want to go into.
1. Purchase Minidsp Dirac EQ.
2. Buy panels.
3. Move the subs around.
4. Fight with the Wife.
5. Fight with the Wife.
6. Fight with the Wife.
7. Return everything I purchased.
8. Blame Youthman.
Hahaha dude I’m so dying right now. That made my day!
This was good! Lol
Lol, man no lie
😂 seriously huh?
That is the problem with some of this stuff. There is the possibility it will show you problems you never knew you had. And possibly some you simply can't fix because of room limitations. Maybe you don't own the home or your other half won't let do what you want in that particular room. When you didn't know you had the problems you thought it sounded it great. When you see them on a graph suddenly you can hear them and now you are not happy with your system lol. Or in some cases you spend day measuring and correcting problems only to find out you actually liked the way it sounded before! Or you can't percieve the difference and it still sounds the same to you. Oh the horror. Sound is a funny thing. Maybe you like a lot of bass, maybe you don't. Maybe your ears are jacked from years of factory work and rock concerts. Your ears and brain don't hear like a microphone.
Very informative video on a subject I think many might not usually consider when placing thier subs. As you say, placement might be mostly dependent on what's convenient. I remember when I first got into hometheater and I would hear subs in the store and think wow... Then when I got it home they would sound less as impressive. The placement makes the world of difference in most cases. This is just another testament as to why dual subs are always going to be the better option.
Thank you Richard
Great video as usually!
I run 2 R115SW and had a very big null. I can't remember at which frekvency, all I did was to turn one of my subs 45° and changed the delay and it was completely gone. I couldn't place it anywhere else becauce it's in my livingroom. You can really work some magic with REW and a DSP.
Cant wait to watch this - great content buddy 🤙🏻
These nulls are easy fix at 1 position. Hell comes down when you wanna make a relatively flat response to multiple seats !
Cant wait for the mini dsp review!
Love the content.
Thanks!
Always coming out with the best videos! Nice job @Youthman :)
Thank you kindly
Great and informative video. Seems like this goes to using more subs in different positions seems to balance out the nulls and peaks of a room that a lot of testers seem to find. The AudioKinesis Swarm subwoofer system is based on theories/ideas from Earl Geddes and Floyd Toole. By using 4 subwoofers appropriately positioned subs, the system is supposedly able to substantially smooth out the peaks and valleys almost eliminating the sound signature of the room and leaving smooth bass. I haven't heard this system but just from me doing the old fashioned room crawl for one of my subs, and then placing the second one in the best sounding position on the back side of the room with both playing, the bass was much better then what I could get with only one sub. Was looking at adding a third (Sunfire) sub but now with you testing the 115r's, am holding off till you complete the series of videos on these puppies. So far I like what you've been saying on them. Love the SVS's but they are just a bit out of the budget. My wife just shakes her head....
Great demo of REW and the benefit of multiple subs.
Thank you
Another great video and now waiting for your minidsp review. Thanks a lot.
Thanks
As always an excellent video test. Great video 😎👍
Thanks Ricardo
Nice fundamentals Youthman. You covered the basics well. Nice video. Cant wait for that mini dsp review. I've been curious about that for some time.
Thanks Justin. I’m apprehensive to tackle it as with most things, it looks like there is a descent learning curve
Thank you Youthman!! This is very helpful Video.
Glad it is of help
I have the klipsch reference premiere hd wireless 5.1 system and I have my subwoofer beside my sofa. So what do you recommend should I keep it beside my sofa or should I change the position??
Might be a good idea to concentrate on those tone areas with some 30 -40 htz tones to see if its a fault
in your subs not the room. Use your reciever to balance out the subs if its a modern one i will have a equaliser setup in the menu of your reciever somewhere helps greatly .
Great vid bro. Hope you doing well. REW is a must imo and it took my system to another level. Mini dsp is also a must especially if you have multiple subs.
Thanks Avon. Yes I now have to devote some time to learning how to use the MiniDSP 2x4 as I have one in for review
Great idea and a good video ! I would have liked to see some measurements with some phase-correction on at least one of the woofers. Could be an explanation for not being the sum of both one-sub-only responses.
Hey youthman. I'm still learning. So do you have to use a demo disc in order to use this software to measure ? Or how do you set it up. Thanks
Hey man, great informative tutorial! Very easy to follow step by step video. Great useful information again. I definitely need to invest in one of the microphones to calibrate my system. Thanks for another great video. Your video is a very useful tool.
Thank you! That my goal. I want everyone who watch my videos know exactly how to replicate what I’m doing.
in some cases a bass trap can fix those issues, but a proper bass trap that work in the 30hz range is big and expensive. but it will do wonders for the bass fidelity on top of that.
Your Null is almost 85 DB. Suggest you do a test tone at that frequency and see if you can hear it at the same volume. If you can hear if ok you can then try reducing the other frequencies down a bit to match the null a bit better. Then you can adjust your volume accordingly. Good video as usual:)
Good idea
Most people have pretty sensitive hearing around 40-50 hertz. I am willing to bet you won't be able to percieve that dip when actually listening to music or a movie. I would personally rather have a dip there then a peak.
Great video Youthman. I'm excited to start testing out my current and new subs to see what kind of awful acoustics my room has! lol
Haha I know I’m afraid of what the PB16’s are going to look like behind my screen.
Hi I just wanted to say that I really enjoy watching your channel ( great tech ).
Thanks Peter!
Do you run the sweep with the front speakers on or disconnected?
Youthman, thank you. I got my Umik today and I already ran into issues. The result I was getting when measured seemed off. After re-watching this video, I learned that I choose to incorrect calibration file. I should have used the 90-degree file.
Cool. Yes the standard file is if you are aiming the mic at the speaker. I haven’t used that one yet
That thing would have a heck of a time with my 5 subwoofers. I'm stuck with my sub placements. 😆 Thanks Youth.
Haha I bet!
What about putting one of the subs into phase? Would that help?
Question, what room size needed to support either a 2,3 or 4 for 12 inch subwoofer
On the upside you already have the mic and software. One thing you can do is make a grid of your rooom, or mark every place you could put the subwoofers. Then measure in those spots with the sub placed where you sit. Find the spots where you get the best response and then place the subs there. You could also mess with the cross over points and phase swtiches too and see if that helps. Audioholics used the mini dsp unit and they really liked it as well.
Good idea but no grid needed. I recently measured and found the best locations on the floor in my room.
Great video
Thanks Travis
Youthman thanks so much for your videos,I always enjoy them and your insights are appreciated for us rookies. Hope your Christmaas was awesome and best wishes for you and your family for the new year. Ps. I treated myself to 2 svs pb2000 for Christmas 2 more days for shipping and it's play time:)
Thanks Mike I appreciate the kind words. Hope you and your family had a merry Christmas as well. And congrats on the new subwoofers
Great video! Also shows how much dual subs can help.
Thanks
I just posted a new video that also shows the benefit of dual subs - czcams.com/video/UjLehLSxXJk/video.html
Great video. Wonder what happens when you change the phase on the subs?
It changed but it didn’t fix my null
@Youthman Can we use audyssey Mike provided with the Avr for testing with REW?
Question ..can i place my Klipsch tall boy speakers on top of my 12inch Klipsch subwoofers ?
What a helpful video thanks! I’ve bought the UMIK mic a month ago and began testing on my dual R-115SW’s but I notice that you are meassuring with L+R, I always thought that the center with the subs was the right way to measure. I also noticed that your combined output is 90db instead of 75. Isn’t that too much bass?
Honestly, I’m not certain what is the best settings. I’m following recommended settings from guys like Subwoofer 101 and Audioholics.
Great video. Can you do a measurement video with the SVS’s and the LaScala’s ? I think it would be very interesting
I have never measured main speakers, only subs at this point in my REW journey
Good video!
Thank you
Which amp play clear with good graphic EQ in but must be good graphic equalizer because without EQ most amp do not give good sound what do you recommend
you definitely need measurements for a better room acoustic. there must be enough space for absorber material behind the screen. some targeted activities in your room will help you more than each electronic or speaker components. greetings from germany.
Wow Great ,It's a wonderful presentation ..Keep continuing ur good work. I want to see how ur SVS responds in that position.
Thanks!
Hi great video as usual maybe you could show how all the connections go between the mic / laptop /avr
What do you want to see? a usb plug? some rca jacks? ..SMH
Hi Robert, I ha e that in previous videos
Just got My Mini Mic from Amazon, The plan is to test Subs this weekend. oh and I used your link.
Thanks! Hopefully the videos are helpful in how to set it up and at least run some basic tests. I have sooo much to learn about REW
@@Youthman I will be watching your videos and looking for other how too's
I have several videos on REW
Good tool
The null that you have when running both sub could be cause by the phase of both sub due to the unequal distance. Try adjust the delay one of the sub and see if that improve the freq response.
Thanks Pierre. I did try that and it made it worse. The R-115SW do not have a variable phase, only a 0 and 180 toggle switch
Nice one Youthie! But you know what, even though I'm getting a dedicated theatre room built in our new house, I'm still going to place my subs at the front in the corners anyway...yes, they may not be at their optimal position, but they'll still do well anyway...i just want to keep the room tidy and uncluttered...
That’s what most people do (including myself) but I’m finding aesthetics isn’t always the best location. Regardless, it’s your room to place them where you please 😀
@@Youthman just get bigger subs! Lol😅😄🤣😂🤣😂🤣🤣😂😅😄😄
I have Dual SVS PB16 Ultras in my Setup. How much bigger does one need? 😀
@@Youthman EXACTLY! Although I'm considering a pair of those Klipsch 15's the ones you've been testing👍
Cool stuff
Thanks Darin
Have you REWed your PB1600’s? I’m curious to see what the curves look like and see if you can use the EQ in the subs to flatten out the curve if they have any issues.
I have been so busy with other videos, I have not had a chance to use it for my own system yet LOL
Anthem MRX and STR series ARC ( Room Correction ) ..should be dropping a new version VERY soon. I think the statistics for high end systems using ARC will speak for themselves. Might really be something to test against the other brand calibration systems. ( Including REW ) however, might be a lot of work to compare them all.
Would definitely be a challenge comparing different room correction software.
Thanks for posting Youthman. Since you will be doing the minidsp 2×4, perhaps get the HD version and add the DiracLive software as I believe the HD version is the only one of the 2×4 it will work with. Would love to see a video with the minidsp 2×4 HD running DiracLive.
Thanks Kevin. I have the 2x4HD in for review. Just have no idea how to use it yet 😂
youthman, would using any of the features in the SVS app do same or all of the same things that the miniDSP 2x4 does? also.. I am running dual SVS SB 4000's and have done some experimenting with placement and when I go into certain parts of my room the response is so much better than from my viewing area. Maybe we could chat on facebook HTE? I am not dissatisfied with the subs, I just feel there can and should be more output at the viewing area. Thanks as always for the informative videos. I think I am going o purchase REW to help with placement due room characteristics, as well room treatments.
which projector you use?
Having the subs in two different locations in the room will cause wave interference, or comb filtering. This will cause man peaks and nulls in different places in the room at different frequencies. I’m guessing the subs are placed 12-15 feet away from one another? Where the distance difference between the sources equals an odd multiple of a half-wavelength, the sound will cancel and you will hear no bass. It is difficult for humans to locate the source of bass frequencies and subwoofers are essentially omnidirectional on their own, so it is often best to place both of them together in the location best suited for the room. Now, placing subwoofers together begins to get into the realm of subwoofer arrays and a whole lot of audio theory that is neither necessary nor practical for a home theater, but it does solve some of the phase issues shown by the measured response curve! Keep the videos coming! Cheers.
Thanks Devon. The location I placed them was where I got the best response. I might try one last location and move the mains inside and place the subs in the front corners.
@@Youthman if you haven't tried, angling/ rotating the subs is an option
You say DSP can't fix the null, but have you tried corner bass traps? That might help with the null. At any rate, every room will benefit from bass traps, unless the room itself has been built to specific dimensions (like a high recording studio for example).
I actually had two corner bass traps stacked for 10 years. Recently I ran REW to measure with them and without and there was no change in the results.
Hopefully I am not too nosey, but I was curious how well your PB16s end up measuring on REW with their current placement. Thanks for the wonderful content as always!
Thanks! No you aren’t nosey at all. Honestly I don’t remember how much testing I did with them behind the screen but I am curious now lol. Once I finish the videos on the Reference Premiere System, I will have my system connected again and can take some measurements
@@Youthman Can't wait to see the results! Thanks!
Me too haha
How does your subwoofer know you want to measure it ? Either connect it to your conputers soundcard somehow or connect your computer to avr ?
Bro you are awesome. Quick question I have Klipsch fronts, centers and back/surrounds. Would buying a top of the line SVS subwoofer kill the sound “harmony” with the rest of my Klipsch setup or should I just get a Klipsch Subwoofer?
Great question. Absolutely nothing wrong with having a different brand subwoofer. It will not kill any harmony with the rest of your system.
Youthman thats why you’re the man. Thanks!
I try
Great video, as usually. How about, if you flip the 180 switch?
I know I tried it in one location with no effect. Need to try it with both subs
@@Youthman So the 180 switch, does not have any effect?
It depends on where the sub is located. I remember running REW with one sub and changing the phase to 180 with no change. I did not try the other sub or with both subs
Quick question. My older MacBook Pro doesn’t have HDMI output, but it does have TOSLINK. Will be good enough or is time to upgrade my computer?
Great question. Toslink supports up to 5.1 so I don’t see why not. Trying it would be much cheaper than replacing your computer.
I have four identical subwoofers. I placed them right next to each other and filmed them in slow motion to watch them move. All were set to the identical phase which is variable from 0 to 180. Despite identical settings of phase for the subwoofers they were moving in and out at different times. I never would have known had I not filmed them. Any suggestions on fixing this?
The problem isn’t with your subs it’s the frame rate of your camera. When I film my subs moving, the frame rate of the camera causes the driver to look like they are warping when in reality they are not.
Can this software measure one channel per time ? Or when u send the test tone of sub the front speaker play together ?
If you have your mains crossed over at 80Hz and have your receiver in Stereo mode, the front speakers and subs will play but the subs are only receiving frequencies around 80Hz and lower and the mains are playing around 80Hz and above.
@@Youthman Cool your video comparing subwoofers, with it you can see what happens around you, it follows an idea: It would be interesting to create a specific video for configuration and calibration with Rew, specific to the sub and also each speaker, giving examples of basic necessities. Other than that, congratulations.
Thanks
So, did you run Audyssey on those Klipsch subs before you ran the REW test?
Or would that even make a difference? Isn't Audyssey for room correction?
Audyssey is turned off prior to running REW.
@@Youthman I suggest to measure after a Audyssey calibration to see how much it improves or not
Good suggestion
Could you show us measurements for the pb16 Ultras?
Yes after I get the Reference Premiere System since I have to move all of the front speakers and subs to get behind my cabinet
My room is a bit crowded with two 7.2.4 systems lol
I have always wondered how phase impacts a room on two competing subs. Would you mind setting the phase on one at 180 (or other setting) to see if it had anything to do with the null at 35-45? That null isn't present in your room unless both are up. Perhaps that is simply a colliding wave that is present when the two frequencies hit? It would be interesting to see how phase changes these frequency interactions.
Great suggestion. I’ll try when I get home from work
@@Youthman I'm enjoying these REW videos.
Yes, I think some fine tuning of the phase might eliminate that null. If they were in phase, I would expect them to sum and help fix that null. Instead there seemed to be a bit of cancellation occurring. I don't the 180 degree phase switch would do it because that might be too drastic.
I'm curious what Audyssey would do to this. Does Audyssey on the Marantz SR8013 EQ each sub separately or as one unit?
Last thing is that the way the graph is zoomed in, makes that null look way worse than it is. It's 6dB, so it isn't good, but it's fixable.
Thank you. I have it zoomed in so it’s easier to see the graph. I could Zoom way our like I see some do just to make it appear flatter 😀
My SR8012 has dual adjustment. Would adjusting the delay (distance) in the receiver help this?
@@Youthman You're zoomed in just right. I'm just saying visually, it looks worse than it is.
Setting the delays could help possibly. That MiniDSP will really don't trick.
From my understanding, Audyssey on most receivers just sets the levels and delays for each sub, but it sets the EQ for both as a single unit.
I gotcha. Yes the EQ is likely the same for both. Levels and delay can be adjusted independently.
You would want to use the miniDSP 2x4 HD
That’s what I have in for review
how did you connect rew to your home theatre system?
Laptop to AVR via HDMI. UMIK-1 to laptop via USB
@@Youthman thanks for answering, really love your videos and now im on the home theatre journey too. What hdmi did you use? arc or input?
Please bare with me, I‘m new at this!
1. What levels should my 2 Klipsch Reference R-12SW subwoofer be when testing? (Gain & frequency)
2. And what do you suggest I set the REW settings for the testing???
Thanks!
Wil Thomas I don’t really think it matters to much. When i lower or raise the volume I get the same response. 10-200 Hz will cover the whole subwoofer range
Wil Thomas I’m not sure if I understand you question. Did I even answer your questions?
Bak Oe So Sorry for the typos... I was just wondering what frequency should my subs be on when running REW.
And what settings should REW be set to.
Wil Thomas 10-200 Hz and -12 dbfs for reference. You don’t have to have it that loud Of you don’t want to
Wil Thomas The mic should also be set to z weighted (if you use UMIK-1)
There's no way to reduce the nul?? Do you have to live with it? Have you done anything since making this video about it?
Yes, take a look at this video - czcams.com/video/eXfH9WH8Yw8/video.html
And also this video - czcams.com/video/_ZxbM_s4vh0/video.html
Can you show us the measurement compared to the PB16 ultra's??
I don’t have them hooked up. It still might happen, it’s just a pain to move all of the speakers to get behind my cabinet
That is what I would be interested in seeing/hearing. Visually it looks nice having duals both up front but heard might not be the best positions. So to see the REW do the sweeps and give the data is interesting.
You are correct Jason. It might not be the best location in my room.
I'm curious what the rew sweep looks like before and after room eq in the subs and afyer the amp does its correction. I have a umik and have moved subs all over the place rinning test afyer test. Sweeps before and after audessy. Changing phase also. Audessy does a good job of correction, but what does audessy and in sub correction look like comapred to no correction. I know it's a lot of work, but I think it may be worth the effort for those who havnet seen it done it. Thanks for the content you create.
Thanks Neal. I’m quickly seeing the deep dark hole of REW haha
Hi Youthman, where can I find a cheap equipment to measure the subwoofer frequencies in my room?
You will need something like this - czcams.com/video/7y8go8cdZ6Q/video.html
@@Youthman thanks I appreciate it... I always watch your videos. Another question and sorry for bothering you. Is it possible to match a Monolith 10" THX and HSU VTF3 MK5 in a very small room (1300 sqft)?
It’s fine to match sub brands. I just recommend not mixing sealed and ported subs.
Hi sr. I hope you got a great Thanksgiving. Sorry for bother you, can I send you a file of my measurement using rew and umik 1? I don't know if the graphic is ok or I have to do more measurements
Yes we had a great thanksgiving. The best place to share your results is in the Youthman Crew Facebook group where many others can share insight with you.
Now do one on the svs subs please
Will do
what about having a sub in the center of the room then in the back?
No room in the back
what about the center of the room? i may have to move my sub soon because i am getting a projector and have to move my mains outward and my sub is now in a corner and will have to move it
"I'm not trying to say I have the perfect setup" Proceeds to show off the perfect set up.

What does a full 20-20k sweep look like?
Why would you sweep a sub at 20K?
@@Youthman : You wouldn't; he's interested in a full sweep including left and right.. :)
I guess I’m not familiar with that. Still extremely new to using REW
You'll drive yourself crazy messing with this haha..It's all depends where you sit..
Yes but it sure is a lot of fun
Why are my towers playing the sweep and not my sub?
I sit on the speaker. Is that bad?
Only if the woofer is facing up.
Weird thing is, I get the best response from having my 2 subwoofers in the front left corner lol. My room is so weird lol. I spend hours Of moving them around and that was the best spot for them
That’s great that you were able to find the best position for them. Did you use REW?
Yes i used REW and man that was a workout. Took like 3 hours Of moving the subwoofers around. Just trial and error over again. I did use some equalisation to smooth it out a bit. In that corner I get CRAZY 10 db boost in that 20-30 Hz range compared to the 40-80 Hz range. The sensation Of the bass is insane now. Bass is a pain in the ass to get right, but sure is fantastic. I am wondering tho, do you think that 10 db boost could be a Little strong? I want to be careful not to hurt my ears so it does worry me🤔
10dB is perceived by our ears as twice the volume. You want it to blend well across the frequency range.
Youthman So you think I should lower it? Do you think a 2-6 db boost would be fine? I do feel alot more bass now and don’t want to get rid Of that. Might just test what sounds the best
Take a photo of your settings. Try changing it and see how it sounds. You can always change it back
For some reason I thought you were screen capturing until you walked across your camera shot on your projector screen. Weird
Nah it’s easier to just show my projector image.
I'm using this: www.dspeaker.com/en/products/anti-mode-8033.shtml
with my R-115SW(i'm using that 8033S-II) and with that, i can make my sub to work literally anywhere in my room.
What do you think of that, Youthman?...btw, that is totally Finnish product, truly a high-end product! :D
I'm quite sure that if you were using that anti-mode with both subs, those measurement lines would be really different
SO I suppose you better move your subs to a more ideal location... LOL... Just use DSP to balance them as much as possible. I know when it comes time to measure mine and making adjustments, moving these monsters to another location isnt going to be one of them. Moving them to another location would destroy the feng shui of the room.
Bad thing is I don’t have much floor space. This was the most ideal location
did you tried the Dayton Audio OmniMic V2? They all say it's the BEST and it's worth the extra $200+
No this is my first mic. Works great from what I can see
@@Youthman yes but it can't measure correct until 10hz or even 5hz as the omnimic can. This is what they say. So i'm not sure if your measurements from today's video are correct
Go and check 123toid video about it.
@@HowDareYouu OR, the subs can't even produce in that range (they stop at 18hz in published range). That's asking a lot from them, and so far out of spec, is it worth $200? I did notice that the Klipschs vs the SVS had differences on the graph so the uMik was picking up something measurable in those ranges in a previous video. But again Youthman is filthy wealthy, so whats $200? :)
@@tkcdac it's better & unfortunately i will spend the extra $200 czcams.com/video/-WyW7S6u1FI/video.html
Haha you do realize these are in for review. Nothing filthy rich about this guy 😀
Easy. Put all your subs in each corner of the room. Case solved ^^.
What if you don’t have any available corners?
I know that REW with good mic is probably much more accurate but have you ever tried mobile apps called Spectroid, or RTA if your using Iphone? Here's a good video about Spectroid: czcams.com/video/giG7mQ0QJdM/video.html
You can't always fallow microphone test and graphs this devices hear things most human ears wont hear so i always tell people use your ears or friends ears to adjust your bass . You will know when its boomy or when theres no bass. And another thing its very important to prevent room out of phase bass cancelation you can get when using multiple subs in front and rear of the room, your fronts subs need to be set 180 degrees and rears 0 degrees to prevent bass cancelations.
Although that sounds like it would be good advice, it’s not. I realize not everything that can be measured can be heard. But frequencies from 20 Hz to 100 Hz can absolutely be heard with our ears but can best be adjusted when you can see those measurements. So if I were to ask you in your room what frequencies would you need to adjust that are Bhumi could you tell me? Could you know what frequencies to cut using EQ to flatten your response? You can’t without taking measurements. Otherwise, you would be guessing.
@@Youthman your forgetting that best guest its what we got to work with as none of us have the perfect room to begin with. You can measure all you want but at the end room acoustics are going to interfere with your frequencies adjustments and you will not hear it as the mesurements are telling you. So why complicate yourself with all this frequencies bouncing everywhere at the speed of light creating all kinds of nulls, highs ,lows, ect. I have been installing profecional theater for years now and learn to trust my ears. Get 2 or more subs to get even well distribute bass and dont go overkill within your room size , so the 20hz bass long waves can be well distributed withing your space. When you start using overkill subs with too much amplification you run into harmonic acoustics issues withing that space. So i tell everyone if you have 2 or 4 12 inch subs and the gains are less than half and the bass is good and low and your not able to pinpoiny where your subs are your good and there is no need to be going to 18 inch subs with massive amplifications in that specific room. You will just drown that room with too much and start running into acoustic issues within than space. Remember the stronger the 20hz or 40hz wave the longer it will repeat and bounce back and forth. Listening its different for everyone and you can't try to adjust any soundsystem with graphs and microphones alone. You can use it as a reference or guide but at the end that speaker or sub its going to go where it sounds the best and looks its best to you. Because to begin with, bass drivers are not to be put on floors they are best high away from floors, so what are we going to do in our living rooms or not so perfect home theaters create hangers and flote our subs in the air all around us🤣🤣🤣 . So dont go so crazy with acoustics or microphones and graphs ect. Set your system fallow the guidelines and let your ears be the judge . If it sounds good to you it will sound good to most, because their will allways be someone will either complaint you got to much highs or too much lows or vice versa. You will never make everyone happy no matter how many microphones or analyzers you use to calibrate any room. I come to learn this after 30 years of profecional installing home and car audio. AMAR BOSE was right its withing the psychoacoustics of human hearing and not the specs.
I agree none of us have perfect room, but disagree that best guess is what we have to work with. I personally would rather measure, make adjustments, then confirm with my ears that it sounds great rather than guess, and see if my ears like it. Regarding 18's being too much, that's the entire reason we measure to blend the subs with the rest of the system. I have always said, "The only time you should notice your subwoofers...is when you turn them off." As you have mentioned, you should not be able to localize them in your room. With all of that said, I'm not a huge measurement guy. I do use REW and UMIK-1 and miniDSP for my subs but I don't measure my speakers. But I certainly see the value in those that do. But at the end of the day, as long as you are happy with your setup, that's really all that matters. Have a blessed day.
Let me explained why you have to becareful with too much sound preassure for a specific room size. I give you an example: If you have a road thats design for 45 mph to drive on you can buy a Lamborghini Diablo and drive on it, but you will never be able to open that lambo and get its full potential as you will soon find out you will run into all kinds problems on that road that its not design for high speeds, now take the lambo to the track thats design for Nascar's and you will find out what your lambo can really do. You can buy the lambo and look good but if your on a 45 mph road , keep the throttle at 45. The road is your room size the lambo its your sub and the throttle us your gain. Hope this helps. Good luck . And try to keep things simple not complicated. As Hometheater is a hubby to be enjoy.
My entire channel is about keeping it simple. I do my best to make even difficult things easy to understand for my audience. I will never reach the full potential of my setup as my ears will give out LONG before my system does. Yes, I do not have a race track or the Autobon where there isn't a speed limit but man it sure is a LOT OF FUN feeling hte rush of massive acceleration getting onto the interstate. :) If we aren't having fun with this hobby, there is no reason to be doing it.
Keeping with the car analogy, I would personally prefer to have a car that has more power than I need, than to have a car that is running close to max performance to obtain what a more powerful car could do without breaking a sweat. Car will last much longer when it doesn't have to work as hard. And for those times when you do want the performance, it's there in spades.
Saying that that location will cause boominess 4:49 is misleading and wrong information. It's a lot more complicated than that. It's not as simple and B&W as it looks. It's not boominess, and you could make the sub sound worse in different placements.
Where the comments at????
Haha
Youthman 😂 great video keep it up!
Thanks!
🙄
Sorry... but this information is misleading
How so?
The point of the video isn’t to say where is the best location but rather the fact that sub placement matters and can have a huge impact on how it performs.
@@Youthman You claim that one sub is at the screen and the other is right behind you, you say the dip in 38>45hz is a room error, how do you know this fact ? have you done correct phase alignment of your two subwoofers prior to this ?
@@mwaldhauer thank you for the reply. I'm very new to using REW and have not gotten to phase alignment yet. Any suggestions on a good resource for how to do that?
What if I tell you God gave you ears to pick whatever it pleases you the most? Are you even serious picking locations based in an artificial device?...
So you’re saying your ears can determine whether or not you have a flat frequency response in your room or not?
@@Youthman I said what I said, precisely. If you let a device tell you what to hear, that's a personal and extremely serious problem. Same with tv calibration. God gave you eyes, and yours are different than mine and the device... Both our eyes and ears also change overtime. Basic common sense. Could care less about frequencies. Tinkering with a sound system isn't freaking rocket science. Test, feel, see, and decide. No machine choosing for you is going to improve your experience....

Hubris comment and extreme ignorance.
Same God that gave us rain, also gave us the ability to build a boat.
Mic is a measuring device.,
Same God gave us the ability to actually measure things to get an objective view.
This channel is helpful for the Adults.
@@MrInfoPhilly Not the same at all, a mic is not your ear. You have to please your ear, not a mic, hence the best calibration is with your own ear, tailored to you...
