Hello, I’m looking for ideas for a music room I’m going to build, where I’ve some freedom to embed some bass traps. Room size is 23*16*10 with wood floor and concrete ceiling. It will be dedicated to audio and cinema but I’m not interested in hi-end HT. Optimization will be done for music listening. Walls AE and ED are made of concrete, with two windows, can’t touch anything here. Wall C-D will have a closet behind. Can I build that wall (part of it) so the closet itself can act as a bass trap ? Hanging double plaster walls, or rockwool panels covered by perforated panels ? The same for wall A-B, where I have some depth for embedding a trap. Plus, I’m going to place some big traps on the corners, top-bottom, and on the ceiling. Any hints will be appreciated. Thanks in advance. Carlo. .

A solid wall will preclude a bass trap. If you want a bass trap on the back wall, fill that space with fluffy pink or yellow insulation and don't enclose it with a rigid wall but for cosmetic reasons, cover it with "open pore" acoustical fabric.

Yes, like rock said, you won't get as much value from your absorption if you put rockwool in front of it due to it's reflectiveness.
Also, your A-B wall is a bit tricky because, ideally, you'll have symmetry ahead of the listening position. At the very least, don't treat one side wall heavily and the other lightly.
Thanks.

hi guys, thanks for answering. The back wall (C-D on the picture) will divide the music room from the closet, which will be used for storage. That wall is 16'*10', I don't want to build it as a huge rockwool panel, since I have to use it on both sides. My idea is to build it as a normal plasterboard wall to allow hanging things, but leaving some big "windows", let's say four openings 6'x3'. Then fill those windows with rockwool or fiberglass panels covered in acoustical fabric. Is it effective in your opinion? How big the treated area in order to achieve a good result ? thanks a lot

OK, here's and idea- If you need to use the wall on the inside, is it possible to hang shelves or other stuff from the studs and leave the dry wall off completely (inside and out)? So if you build a 2x4 or 2x6 frame partition wall with stud spacing to accept say 24" wide insulation, you can cover both sides with fabric and you have a fully absorbent rear wall with extra space behind it which will enhance the LF performance. Additionally, around the ceiling, side and floor edges of the back wall, you can use paper or thin plastic membrane on the front "like our regular bass traps.
Now that I think about it, why not frame corner angles in the wall and ceiling to more effectively trap bass. Of course, you can't do that in the "D" corner since it looks like there is an existing door. But if you can move the door, well then you can angel the corner too.
Of course, you can also leave only holes in the wall too but that's a lot less effective.

Even so, 2' of insulation is pretty obstructive to line-of-sight.

yep, shelves are a good option to keep the storage functionality together with a big mass trap. thanks a lot Rock
