After all upgrades over the last year, I'm at a point where the room is definitely the limiting factor. So now it's time to start room treatments. I found plans for acoustic panels over at http://www.instructables.com/id/Make...o-or/?ALLSTEPS. These look like they'll produce some fairly pro-ish panels. Does anyone have better instructions? That they'll share, that is?
Now, as to the treatment itself, my room layout is about 15.5Wx18.5Dx8H. Not ideal, I know. But it's probably the best room for audio in the house, so it'll have to do. The front, back, and one side wall is paneling over sheet rock, which will eventually be just sheet rock when I finally stop buying stereo stuff and start remodeling (haHA). The other side is a fireplace (brick) next to a sliding glass door. The door has a fairly heavy curtain over it. The back wall also has a 6x6 bookshelf filled with records, so I expect that should act somewhat as a diffuser. The back wall also has a large 7x7 door opening into the rest of the house.
That said, my initial plan is to build a total of 11 panels. Panels will be mounted 3 on the front wall behind the speakers, and 4 along each side wall at the first and second reflection points. Bass traps will come later.
The other question is whether to go with 3# or 6# for the panels initially, given the liveliness of the walls. Anyone have any input on this? I'm thinking 3# should be fine, and 6# might damp too much, but should be perfect for the bass traps.
The other option that I'm considering is rotating everything 90 degrees, putting the patio door and fireplace behind me, but I' probably have to move the book shelves to what would then be the back wall. I'm sure some will say that with my 2.3 TLs, I should have them on the long wall, and that's something I expect to play with some day. I just rather like how they sound now, and I'm sitting about 12" back from them. So the concern there is that if I rotate the room, I'll only have about a foot behind me which might make the reflection off the (now) back wall too strong to easily control.
Anyone have any input on these assumptions, or have I missed anything?
