I am not a audio nut by any means, but this setup works just fine
as far as I am concerned. I am using blackout material for a screen which works great with crt pj. It hangs across the
corner of the room about three feet off the floor. In the actual
corner which is about three feet behind the screen is the
center speaker. It is not quite centered on the screen but works just fine. By having it back away from the screen I don't hear
any muffling effect.
