Hi Chad I'm no expert but I do know another website where they talk about both the materials and issues you asked about; http www.ethanwiner.com/acoustics.html. Also Burlap is mentioned by Jon Risch as being less reflective a covering than cotton. I think thicker is better. Tried to make a link. Hope it works, ha!
I've made DIY panels, just got them up this weekend. Have only done limited listening so far. My room is 14x18 with a sloped ceiling. I've got 2 2x6's on the front wall, 3 2x4's on the rear wall, a couple on each side wall, and 2 2x6's hanging from the ceiling. I have to say, I think I needed that many to get the slap echo out of the room! They were easy to build (including wood frames), and easy (but time consuming) to mount. My impression is that a couple 2x4 panels may not be enough - but I'm sure it entirely depends on the room. In mine, I have a 5x8' window that "rings". It is a continuous double glazed window - not broken by any framing at all. Might have to replace it.
Ethan Winer's site is good. I believe that he has designs for making corner traps with panels and/or loose insulation, rather than building tube traps. Check it out.
Chadnliz, your room is not small. In fact, your room dimensions are excellent. My previous listening room was 12.5' x 20' x 8' ceiling. With only 1 set of windows behind the speakers (on short wall), beamed ceiling, wormwood paneling on all walls, thick carpet pad and berber w to w carpet, 3 load bearing outside facing walls, the acoustics were excellent.
In fact, I had a reviewer/columnist over to the house just prior to moving and he said good luck trying to find another room like that one.
The only things I did was replace the leather furniture in favor of overstuffed cloth, installed recessed lighting on a dimmer, removed all tables, and floor and table lamps, etc. to lessen in-room reflections.
My suggestion would be to ensure your speaker placement is optimal within the room as this should have a profoundly better impact than room treatments.
Once you're completely satisfied with speaker placement, then address the acoustic treatments, if you think that is still warranted.
No problem, Ausjoe! It took me awhile to figure out Agon's mark-up tags...just click on the link below the "Your response" box.
I haven't built any panels. I'm using a type of foam, 4" thick, with a pyramid structure that is used in studios. I've covered my back wall, to prevent unwanted rear reflections. My listening couch [also very absorbent] sits right against the back wall. I am listening "nearfield".
I've used loctite power grap, 3m 77 might do the job. Myself I would build a wooden frame around your panel, very easy to do depending on your disability you might ask a friend to help. This will make it much easier to Mount and to put a cover on. But a word of caution breathing in fiberglass is not a good thing. You"MUST" put the batting around the whole panel, then the cover. Burlap makes a very good cover but if your cotten is a nice open weave( if you can blow through it very easy) it should do the trick. I made my cover like a pillow case and then sliped it over then either sew it closed, staple 0r use brass tacks.. Good Luck.
If I have some styrofoam insulation panels in my basement from previous people here, can I use some of these for any purpose? I have enough cover material and batting material, the needled cotton is very breathable and looks great. The panels are 5/8 thick and I can cut them to any size...can these be used at all? thanks again
