Floyd Toole:

"Some people come to this topic thinking that, as is some other things, that there must be a simple way to do acoustical design, a kind of cookbook, that anybody can understand. I wish that were so, because it would simplify all of our lives. As it is, achieving truly good sound in rooms requires knowledge of how sound behaves in rooms, and some effort – or more than a little bit of luck."

no improvement < some improvement < more improvement < perfection

somewhere along that path is a happy medium where physical constraints, budgetary constraints, and desires can come together (and leave an upgrade path). Sometimes the best that can be done is to pick the low hanging fruit and come back later and play in the weeds.

Now, I am almost ready for drywall and have a few ideas on how to treat my early reflections. My first plan was to cover all walls with fabric panels, something like this... (IE wouldn't show the lines in between each panel correctly, try to picture 12 panels there)

Each wall will be covered with 1" fabric panels, and I will have OC703 or equivelent behind the "problem" areas (found using the mirror trick). This way, you won't be able to see the reflection panels. Now, since my room is small to begin with, I can't afford to loose too much more, if any, space.

I would like your opinion on whether or not 1" thick absorbtion will be "good enough" for the early reflections or if 2" or larger is DEFINITELY the recommended. If so, I will have to do some funky in-wall panels, but trying to keep this simple. I will also be treating the rear corners with superchunk style bass traps. I know the thicker the panel or more space behind the panel, the lower the frequency it will take care of, but, I just want to make sure I'm getting good imaging and front sound field without going completely overboard.

Also, I'm not trying to make the room a perfect sounding room, that would drive me CRAZY trying to figure that out. Instead, just the main problem areas (early reflection points and corner bass).

Thanks

If you can leave some of the drywall off, and you don't mind the loss in sound isolation, you can pick up a few more inches of absorber depth by recessing them into the walls.
