I have a 7.1 setup (4 QS8's). The rears are 8' behind me and the sides are 5.5' (I'm also 8' from the fronts). At first I used PLIIx and THX Select to matrix the sound to the rears. Later I started allowing the soundtrack to decide (most are 5.1). To be honest, I can't tell the difference. Many folks would think that having 2 additional speakers behind you would make a big difference. In my experience, they do not.
