Hi Bruce! I'm speculating here. What I would do in your situation is put QS8's on the back wall. I think their dispersion characteristics are going to give you the best effect.

Is there a lot of discrete 7.1 content out there now? My understanding was that most material you would put through a 7.1 system is actually native 5.1 or 6.1 that is matrixed by your processor to derive the other channels. However, the world has passed me by in many other areas
