May I ask what fq. range diffuser do you use behind speakers? Currently I have 1 mounted behind each 34 1/2" tall speaker. Diffuser panels are 2x4’ raised 1’ above floor. This design is tested effective in the neighborhood of 3100 hz on up. Does this sound ok (no pun intended)? I'm a little limited with placement being that theres a wall mounted LCD 3' above floor level.
Diffuse Front Wall? Absorb rear wall?
I'll research existing threads, but quick basic question --- is it a basic tenet that I should use a diffusing approach for the front wall and an absorption for the rear wall behind my listening position? I bought a wall rug, put it on the front wall, and though it seemed to quiet the room down in some good ways, it seems to have sucked some of the energy and sparkle from the soundstage. thanks.
