Also for what it's worth I helped my dad set up his QS8s in his room at his new house. His couch sits against the back wall because unfortunately there is no other option in his room. We mounted his QS8s same width as his fronts on the back wall at a height roughly 6.5' above the listening position on 8' ceilings. He has v1 or v2 QS8s, I believe v2 based on when he purchased them, but they can't really hold a candle to the v4 10s. The sound difference is night and day and the extra 6.5" front driver makes a huge difference too.
