I've got a lot of echo behind my screen. I've got a false wall, that the screen hangs on. There is almost 2 feet of space between this false wall and the real wall. I'd like to know if covering the entire wall and floor behind the screen would help any? My front left, right, center channel and sub are all back there behind the false wall. I was thinking of removing all the speakers and then gluing the foam to the wall and floor and then putting it all back in there. I found this stuff here that seems cheap Acoustic Egg crate Foam
