Ya the spacing and mounting options for the rears is not ideal. With the door leading to the stairs it limits my ability to move the left rear surround much farther over. I thought the rear surrounds, since they are basically mono in 7.1, didn't need to be too far from each other? I always look at these things being symmetrical but perhaps since the right side of the room has more space to be filled it would benefit by having that right rear surround over farther to the right than the left. From a pure cosmetic standpoint I wonder if putting the two surrounds directly over the opening between the two rooms would function well enough from a sound standpoint?

My other concern using my QS4's there would be that they have the top firing speaker. They are going to be mounted so close to the ceiling I'm not sure what impact that would have on the sound.
