I liked that, Thanks, I saw the other video going through the older ones. I am almost caught up on all the Acustic Field's Video's. It's alot to digest even for those in the Hobby for Decades. But it is the Next Level for not only those working and mixing but for the Audiophile also. And as mentioned, when your into the high dollar Equipment, it's alot less expensive to just treat the room.

Instead of rules of thumb, I suggest placing subs where they measure best. Complex interactions from various wall, ceiling, and floor boundary structure and surfaces are endless. So you've just got to experiment and measure... without ruling out any locations, corners included. I realize everyone wants quick rules of thumb of approaches to try, and those to never try. I agree, corner placement of speakers/subs are often problematic. However, there's instances whereby corner placement is ideal for acoustic performance.

Great teaching! So please, what will the size be for a sealed 12”?? I don’t have the room size, yet. Moving soon.

The room that I did the best response was putting the subwoofer in the middle of the front wall!! That's because I had a floor to ceiling modal conflict at 60hz and 120hz. Although it looked weird, the sound was amazing.

I have my system based out of a corner, where the full range speakers are off the wall and separated, but a 12” subwoofer facing into the corner. Amazing bass! I’m really surprised just how much more sound the sub has facing into that corner, as I tried the configuration many ways. This is great on a budget system, if you just have a single 100 watt subwoofer.

Love it, Dig it.

at minimum, I appreciate the audio levels of this video, listening to you talk on my headphones while I debate my home audio helps me make some decisions.

Thank you for this great session. Can I keep the sub woofer above a 110 inch screen?

Hi Mr Foley, what about the Swarm LeJeune/ Geddes method of putting 4 subs randomly with one of them ( the one farest from the listening position) phase inverted in the corner. What,s your thoughts on it!

My dad has his sub in a corner. I shake my head every time I walk by...🤦 Thanks for the vid Dennis! Is there a general rule of proportion for matching driver size and room volume for a 2-ch setup?

I have often contemplated putting the subs from my live systems in the corners of my mix room, but attaching a variable resistor or reactive load to them instead of a signal. My theory is to see if they will attenuate their tuned cabinet frequency. I would love your prediction or thoughts on the experiment.

What about setting yours subwoofers (dual) on the back wall? Pretty much behind you.. unfortunately I don’t have space upfront to place them. It’s either back/front corner or back wall (not in corner) thanks!!!

Hopefull you read this Acoustic field. I have a 24 x36 basement. My issue is i have a drywalled stair case coming down about into the center of the room. I have a pb16 and a pb2000 svs sub. I mostly listen to musice 95%. Id like to have bass in all parts of this room as there is a bar at one end and a game room at the other. What would be your suggestion. Ive split them up to this put. One at the end of the room and the other at the other end. Unfortunently I have put them in the corners lol I will change that now.

Rel advices to set the sub in the corner. I found it strange, too. They say in this way the waves have the most distance to travel to the the next wall. But it rly works.

hey! please make a video about this: my room is not 100% symmetrical,so only one of my corners has a big bass buildup. this is my backwall on 42hz. I have no idea what to do,because I think the energy from the other corner is also building up there

Good day. Is there a ratio for room size to driver size? I'm interested in adding a subwoofer to my home studio setup. The sub I'm researching has no bass ports.

Was looking at REL subs on Amazon, REL recommends placing their subs in the corner 😀

putting it on a dolly to roll it around is brilliant.

Since when does room gain = distortion?

Dual subwoofer set-up best works when the subwoofers are placed in opposite diagonal corners, unless the room is very small, don't let anyone tell you otherwise. Of course it's way easier to set up dual subwoofers on the front wall inside the front left and front right speakers, but opposite diagonal corners will have the better sound.

do you recommend 1 or 2 subwoofers in a big room ? (I want to play under 80hz with them).

Now I have to dig into sub placement, because mine is in the corner, and that is the only place in the room where it makes good sound. Anyway, I'd like to get another sub, and have it on the other side. I just feel where the sub is, so I will balance it out.

Please can someone guide what driver size is idea for room sizes and link or calculation. I have a 16ft wide and 28ft depth with 12ft height and have 2 10” peerless XLS sealed sub on miniDSP and Hypex I feel I need more pressure especially when I listen at low volume at night Thank You

So if I dont put the sub in the corner like Rel have suggested, where is a good starting point? 🤔

I corner load my HSU sub and place the other HSU sub nearfield and that's the only way I can remove the low frequency nodes. I get flat in room response down to 12.5 HZ and EQ the peaks. What is wrong with room gain?

Flame me all you want, but I've tried to put my sub all over my room. Middle, centered against a wall, different corners. No matter where I put it, the bass sucked in the "sweet spot" for the other surround and main LR speakers. Little he said made any sense to me. A 18" 1000 watt sub in a closet? Ya, agree there. But 2 15's in my Yugo is just fine! LOL. I have an 18" THX Altec powered sub in a corner in the front wall where the main, center, and TV are. It sounds as smooth as a baby's butt as long as I'm not in one of the null zones. I believe that only in a huge ass room, like a 4 car garage with 10 foot ceiling, you may get an almost uniform clean low end w/a sub up against the back wall in the center. I've done it.

For my system I'm going to the near field listening idea...my room is about .maybe 15 by 15...what can anyone suggest for my size of a living room?

I’m considering buying a Lyngdorf MP-40. In the manual it tells you to place the subs in the front corners and let Room Perfect (Room Correction ) do the rest. Then I see this…it’s so frustrating because you don’t know what to believe.

Always delivering the gems Dennis

Isnt the theory with corner placement is to excite the nodes / peak pressure to then apply automatic room correction to smooth out the eq response and time align phase? Its cheaper and more convenient for most people to dump and forget and use eq than to spend a huge sum of money and occupy needed space with bass absorbers. I appreciate your method has better results and is some what niche however the trend is most people want a simple life and easy wins. Imo, there is no such thing as a right / wrong way to do something. Just different levels of madness. 🤪

So many sub choices out there, REL seem to have simple integration and their size is perfect. Right now a bunch of youtubers are touting the Speedwoofer 10s and 12s as best performance to value, although the 12s is gigantic. Then there's Hsu and SVS....🤔🤷‍♂️

Balanced.

Could I Corner load one sub and have one subwoofer in the dead center of the room

I’m shocked that you don’t understand the theory about the room modes and yet you are selling products for room treatment. Primary modes have opposite phase at the opposite corner. Having four subs in the corners playing the same signal means that the modes are cancelled.

Hey I'm curious to know, are you against tactile bass ?? Because some scenes like gunshots, bomb blasts, dinosaur foot steps etc gives great movie experience when there is a good tactile responce that you can feel through the couch. And also chest kick in some movies. If you are not adding more energy to the room, we can't get tactile feel. What's your opinion on this ??

But what about the Klipsch CORNER Horn! THOSE Sound quite delicious?

Yes. Don't. Unless... you really hate your neighbors. Then by all means, put it on the floor in the corner and your downstairs neighbors can also enjoy the bass of your music. Maybe even the whole building will enjoy it......

Isn't it easier to place the sub in your listening position... then you wander around on the floor to find the sound that works. That is where the sub goes and hopefully it is in a good spot for the room.

If all the room modes end up in the corners, isn’t it advantageous to place bass traps there? In your corner bass trap video you indicate that they aren’t very effective because you’re only treating a small percentage of the total room surface area. That is correct, but based on what you say in both of the corner-loaded subs videos, it seems the corners are the *most important* area to place low frequency absorption.

isnt there a trick where you put the driver on the chair where you plan on being the entire time and you crawl around to hear where it sounds best?

In one video you said that putting treatment in corners was nonsense. This video says that all room modes end in corners. So why is it nonsense to treat corners?

I noticed better sound in my room when I accidentally turned the sub off without realizing it

🤣🤣🤣 Normaly don't tell people to use comon sense🤪 Found that extremely funny for some reason 🤪 I do agree though, no subs in the corner in my space😊

💪

Dennis, For sake of discussion. What about multiple smaller subs instead of one larger one?

The desk is in the middle. The corner is the only physical space remaining.

So why did Electro Voice, Klipsch and JBL, etc. design speakers specifically for corner placement?. The EV Regency III and Klipschorn actually use the walls of a corner as part of the folded horn design. They do need a large room to sound good. I used to have an EV Regency III with an EV 18" in it. I just bought a JBL Control SB-2 subwoofer which has a 10" dual voice coil driver and is a slot loaded, vented bandpass design. It is triangular and made to gain full efficiency in a corner either on the floor or ceiling. The efficiency is less when placed in other locations. They came with mounts for corner placement between floor and ceiling or on a wall for commercial applications. So far I have it away from a wall or corner and is still fairly efficient. I have yet to try different placements. I have either stone or concrete walls and floor with an acoustic tile ceiling, and a unique room, so a different situation than most.

an average sub is 2500 dollars? Really, wow. My PB2000s were 700 and they are 12inch drivers. Id say they are the definition of average.

Stacking of subs is a great con. Firstly, in the concert industry there is no line array subs. It’s never done. Secondly, you get 6 subs stacked up in 2 columns and then use them in low volume for ‘better bass’. Ratio of 6 subs to 2 stand mount speakers. 🤣😂🤣😂

Too theoretical. Use your ears to find what's best.

Love mine in corner :)

If you’re a broke person like me the best option is just to place your speakers where it sounds the best the most natural do you want your speakers not to sound like speakers do you want your speakers to sound like the room if you’re subwoofer sounds their best in the corners if that’s where they sound the most natural that’s where they go if your main speakers sound their best up against the wall that’s why you place them if your speakers sound the best when you pull them out into the room that’s where you placed in your room dictates where your speakers go not everybody’s got Tens of thousands of dollars to do what is the golden standard sometimes you just Gotta do what you Gotta do

I have 9 subs in my home theater setup (7 passive 2 active). I have 5 passives in one corner, and the SQ and SPL are incredible. I challenge any naysayers to listen to my setup, and feel the phlegm clear from your throat, and a 360° air massage from the sound pressure level. Peace
