thought my 12(L)x10(w)x(9) room was gonna be horrible with bass response. Well, i was wrong. Actually....very wrong. I treated my corners with corner traps. Treated my first and second reflection points with broadband absorption, back wall aswell and some diffusion and hung a nice cieling cloud over my listening position...put my sub on my chair lifted up to ear level and did the good ol' "subwoofer crawl" (a technique i thought was bogus but was SOOO wrong) and REW after some room correction showing me a response im MOOORE than happy with, some small nulls at 43hz but not really noticeable to the ears, but other than that? Room is sounding amazing. Im not chasing the flatest response in the world but its flat enough for me to get my work done in that room and deliver quality. Dont say its impossible. Just tackle one issue at a time, and try to get as close as possible. Other than my listening position, does the room sound good? lol no. So much sub build up in the back of the room and still some build up in the front corners but its a critical listening/mixing/mastering room and right whre i mix and work is the only place i need it to sound good and boooyyyyyyyy does it sound good

[@AcousticFields]

Thank you for your detailed response. As one can see, there are certain parts that are impossible.

Imo you can get good results in a small room w7.8’ w l11.5’ 8.5’ Just cover the whole back wall with a perforated panel absorber. Use min 8” thick panels inc clouds on the front wall for first reflection points & super chunks on the front wall and cover them all with a binairy slat sequence to bring back some liveness in the room.. place the monitors as close as possible to the front wall to avoid sbir & spend much time in monitor placement! Especially with low ceilings, just turn your monitors upside down. After all the treatments some room correction & you can archieven some really good results! A-lot of work & research Small rooms can be tricky! But not impossible imo

[@AcousticFields]

D, None of the treatments you have described with address the frequency and amplitudes of the issues presented by that specific room size and volume.

Hi Dennis Can I get a link to the chart ?

[@reensound3557]

hey dennis, i have a quite large room (aprox. 15,5m long, 6m wide and 3.3m height) but i have the feeling my bass gets sucked out (eventhough i have 8 inch woofer monitors). I already added a subwoofer (10inch) to my setup but now i have problems with getting a clean bass sound below 100 hz. It sounds muddy and sometimes i get room modes on low bass notes (around 60-80hz) at my listening position. What could be the cause of that problem? The room is very large (at total around 113sqm counting the stairs and toilet as well) - i thought at the large scale i shouldnt have much problems, shouldnt I?

Maybe, you are placing your transducers in a spot at which they are easily able to excite the Room Modes, also if your room has parallel walls with a good amount of mass, then it can cause Modal Resonances/Standing Waves between them, which can worsen the problem especially in low frequencies. Having a big room is not a fix for any acoustic problem, in fact, due to its Reverberation time it can cause chaos in mixing and Mastering, Having a large room is only a Plus Point for Fixing the issues using Acoustic devices. Simply try to calibrate your monitor levels With SMPTE RP2000 Standards, then take the measurements of Amplitude and Phase using a Pinknoise Sweeps, and after that Scrutinize the web And Acoustic Science books for finding the solution ( Hopefully you will succeed in 4-5 years) or simply consult an experienced acoustician for its Valuable and Professional Advice. Remember, Acoustics is not just science, it is an art that requires Ingenuity and Experience, and both comes with time and Practice, no book or college can teach you it in 4 years, In fact, they won't). A well-designed floor plan, Foundation and Structure layout is the key.

R, You need to treat the issues < 100 Hz. within your room and lower the strength of the unwanted energy within your room size/volume.

(Listening room 12x12x22, music, movies) Is low end dampening most critical on W,H,L or all? I've seen tube type dampeners place in the corners but truly wonder if they really are that effective. I'm also most curious if length plays any roll in dampening lows. Thank you for your continued sharing of knowledge!

[@AcousticFields]

C, This is a common myth perpetuated by companies who sell absorption technologies for room corners. It is the whole wall causing the issues, not just the corners.

[@NathanOakley1980]

Just use 4 subwoofers! Done ✅ Only joking, love your videos.

[@AcousticFields]

Walk us through your 4 sub thinking process.

[@baruchdor]

why not use vpr type traps?

[@Oneness100]

Not enough length to use LF absorption. You need depth to absorb low frequencies. If these small rooms don't have much room to begin with, putting in LF absorption devices is going to take up valuable space.

[@AcousticFields]

S, Spending money on 3-4 sub woofers to achieve a more balanced low end response is not cost effective nor will it provide the proper attack and decay rates within the room.

[@Oneness100]

@Stimpy&Ren So you're going to recommend that people with small rooms, like 9"x10"x8" is going to run out and buy a bunch of subs? You have GOT to be kidding.

[@Oneness100]

@Stimpy&Ren Here's one thing to note. Geddes hasn't heard AF's low frequency treatment and compared it to the sub woofer method. So, until he has, I tend to not believe using subs to "fix" an acoustic problem. I believe Dennis has played around with using subs to fix low frequency problems to compare. Dennis? Have you actually played around with using subs to fix low frequency problems and compared to using your LF treatment methods? Also, I read that Geddes' approach requires certain types of subwoofers that are not common in the market, so I believe he uses custom built subs, which the average person isn't going to deal with.

[@AcousticFields]

@Stimpy&Ren You are missing the point. No matter what methodology whether treatment (passive) or active the energy still is married to the room. Your goal is less room sound not more energy.

Loved the honesty! Even if I´m fucked right now LOL
