Justin, I like your room and set-up. The couch and chairs look comfy!
Hmm, I'd be tempted to try that left rear QS8 on the small triangle of the adjoining wall. That way it'd be facing the same direction as the right side QS8. I know it'd still be behind the listening position and in relation to the other QS8.
Is this suggestion for if I were to just stick with 5.1? I think I would agree with you in that case. But if I were to go with 7 speakers, I think I'd want channels 4 and 6 in line with my head, and then 8 and 7 on the back wall(s)
