My basement is approximately 20'x24.4'x7'4".

It a little frustrating the Two most common standards, audyssey and Dolby have different recommendations for speaker placement in a 9.1 system. I was hoping that a well placed set of QS8s would be able to satisfy both configurations, but from what I've been reading, the recommendation is to go with bipolars(Quadpolars) for the side and rear surround channels but direct radiating speakers for the highs/width channels.

Decisions, decisions.....
