I too am in the this same process. While reading, I hit upon an idea of setting things perpendicular. The speakers coming out of one corner and the listening position in the opposite corner (kitty corner). This was used by a speaker designer that was having a problem with a room and could not tame it with room treatments. I am going to try it. My room is 10x10x8, square is even tougher !
Is 9'x11' too small?
I am considering using a small home office as a dedicated listening room. I could clear out the room and have it dedicated to gear only (and a chair or two and CD racks). This would allow me to acoustically treat the space (as I can't now in my listening room of the living room). The problem is (or might be) and my question to you is; the room is only 9'x11'x8', is this too small?
