I'm finishing my basement and looking for some advice on placing speakers for a 7.1 system. Room dimensions are 14'7" x 19'11", with the TV wall mounted on the 14'7". Opposite the TV, however, there is no rear wall as the basement flows into a rec area (think future pool table) and then some bedrooms. What is an ideal 7.1 setup in this situation? To be honest, the fronts and left/right surround seem straight forward, but the rear surround I'm struggling with since I want to avoid speaker stands. That being said, any advice in terms of ceiling vs in-wall for the surrounds and fronts would be appreciated.
