Mejames, I designed my listening room pretty much from scratch so the corners are in good shape and the size is very good (32'2"x19'8"x12'1"). Heavy sloping woodwork and sloping tray ceilings elimnate the 90 degree corners and ceiling to wall joints. The walls themselves are a double thickness of heavy drywall glued together and attached to horizontal metal rails (I can't remember what they're called, but they are heavy) and the walls are 6 inches thick (offset 2x4's on a six inch plate) filled with acoustic insulation. We just got some very heavy drapes that cover up one entire wall from corner to corner other than the fireplace in the middle. This has provided the room with a very nice acoustic finish. Since the drapes arrived, the PZC's are in the closet. I still need to figure out what to do with two of the corners, but will need something fairly "invisible" and 10 ft tall to the tray. My wife's been patient enough with the rest of it ;-) If I can't get a decent price on the units, I could always use them in the TV room I guess. They are nice units though.
