Hi Guys, I am finishing up a basement theater. The theater is a rectangle with 3 walls . It is 14' wide with a 136" screen. and goes back 22'. There is no back wall. just a boundary where the theater carpet transitions to tile. I have a Onkyo SR606 receiver with 7 speakers. I have 4 floor stands and can get two more. The ceiling is a drop ceiling 2x2 accousitcal tile. 8' high. I plan on having the center channel under the screen. The two fronts about 3' up on stands on both sides of the screen. The Sub about three feet in front of the screen, off to the left side. The sides at 100 degrees from the center of the seating area, on the wall at about 5'. My problem is with the rear surrounds. If I place them in the back of the room, I have two options. Mount on the walls and angle them towards the center. Mount them on stands and place behind the furniture. I fear the latter would immerse the people sitting in that location with to much rear surround. If I put the speakers on stands about 3 ft behind the seating area, which i think is recommended, my kids will constantly knock them over. I think my ideal location would be at the back of the room mounted from the ceiling at 7', angled down slightly. That would require an drop mount of 2' (approx) I can not find any. Anybody here have any suggestions to make this room work??
