I have a similar size room which sounded dreadful when untreated. I have now at last transformed the room with acoustic treatment. I ended up with 17 large wide band velocity traps and 16 large membrane pressure traps. I designed the membrane traps to target the specific frequencies that were most annoying. I now have a room that sounds amazing with no nasty booms or other excessive bass sounds. Total cost of the room treatment was around £3,000 and worth every penny.
@@solo5414 I used 2cm thick timber to make a rectangular frame. The width of the timber determined the depth of the trap. I used 2mm thick rubber sheet as the membrane. I used plywood for the backing panel. I used a sine signal generator to measure the frequencies of the offending bass notes. I then designed the traps using a simple equation. f=170/root (m x d) where m is the membrane weight in LBs per square foot and d is the depth of the trap in inches. The equation is for traps with no insulation inside them. For traps with insulation change the 170 to 143. Traps with insulation are wider bandwidth but have a lower coefficient of absorption at the centre frequency.
I really hoped you would go into the specifics about how to make a mostly square room work, what are the challenges, physical aspects of dimensions etc..
I have our family room partially treated with most of the 19 panels in the front 1/3 of the room but will ultimately move into a small bedroom when one of the kids moves out so these stories are always inspiring!
Hi Jesco, just came here to say thanks as I watched one of your videos recently about square rooms and how to work with them. The bit in particular where you said 'If your room is only a certain size then your listening triangle only gets to be so big'. You suggested working in a much smaller triangle to get the listening position out of the centre of the room. I was worried about my soundstage feeling too small and having other issue like increased boundry reflections due to being closer to the front wall. I can say that it's the opposit and I can hear much more detail in all frequencies. There is a lot more low end but you can work with it. The centre image is much stronger so vocals stick out.
@Richie Whynne THX for your story...same thougts and experiences here especially hearing and trusting! Basslines is very relaxing 🔊🔊🕴🏼 While I was adding more Absorbers I experienced that I have to cranq up the Volume quite a lot. Showing how much excess Energy was there before. My Room is very small, odd, Tent shaped with igantic Bass Build-Up in the Corners an Ceiling. Anyways...Keep on rollin' Everybody!
Do you think it would be an advantage in a square room to make the air gap of the absorber on the sidewalls bigger than in the front and back so the inner rectangle of the absorber is more rectangular than square ? Like in a 4x4m room you make the absorber 15cm thick and on the sides an air gap of 15cm but front and back only 10cm so the innter space is like 3,50x3,40 ? Or maybe even more of a difference in gap.
Hey Jesco 👋 I’ve heard another acoustician on RUclips say it’s important to create a sealed air gap behind the panels. Is this really relevant or true in anyway?
After putting a giant bass trap between my 7” speakers I found that all the bass had dissapeared, which I was confused about until I found out that it was because of all of the room bass that was gone 😅
HI i have been watching many videos of yours but not able to find exactly what to do when you have sub bass low end ringing issue mine is peak at 29Hz and its ringing in room over 1.5 seconds may be more.... as showin in waterfall REW
Ey up, no I'm originally from Lancashire but live in North Yorkshire. Sorry for the late response, I only just found out Jesco had published this video :-)

Hi! Could you tell your membrane traps. How did you make them from what material, as you expected?

Where's he from?....'It's a bit chilly, so I put my jumper on'....ah British 😂❤
Also...great video. Really good to hear the practicalities of Richie's project. Also good pragmatic outcome!
I'm not sure what's wrong with the RUclips algorithm but I wouldn't know you had a new video without being on your email list.

@@chinmeysway 1.2 meters apart. The room is 3.6m x 3.85m x 2.25m. Using Neumann KH 80's with 12inch sub.
My room is 3 / 3,3 m! 😂 Still managed to sound very good.
Your audio is great but could we get 4k video quality please!

Was there a before and after REW measurement?
