Guys,

My room is treated quite well with ASC traps, corners traps, first reflection absorbers and echo busters behind my listening chair but I'm curious if I need anything on the back wall, centered between the speakers? The back wall is draped well and I'm not sure if treatment will help in any way.

I'd like to hear your suggestions; room size is 15'W x 19'L x 8'H

Also, suggestions to the open space or will heavy curtains work during listening sessions?







Thanks,
Wig

To most of us, the back wall is the wall behind you, the listener. That wall needs treating much more than the front wall behind the speakers, especially if it's closer than ten feet behind you. Sound from the speakers goes past your head, hits the rear wall, then comes back at you. If you add absorption or diffusion on the wall behind you, less energy comes back to you and toward the front wall. That's why the rear wall makes more sense for treatment. More here if you care:

Front Wall Absorption

I'll add that reflections from the side walls are also more damaging than from the front wall, so that's another place to consider absorption.

Guys,

Thanks for your response. I have both side and back (est. 7 ft from listener) walls treated with Echo Buster absorption panels. Should I treat the open door way with a heavy curtain or some absortion?

Thanks,

Either would work fine, the curtains would just absorb less midrange frequencies and low frequencies than a full sized acoustic panel.

Any particular product in mind?
