Wow - thanks for the prompt replies!
I think I underestimated - the room is slightly larger - 16 wide by 19 long (screen is at one side of the length). There is about 3 - 4 feet in back of the couch.
It may be sage advice to go with the 5.1 first and rough in the wires for the extra rears while I'm in the crawlspace.
if it is less then you could think about a rear channel QS8 otherwise the M2s are a popular choice.
Can you clarify? You mean a single QS8, or a pair of M2's, even if there is less than 4 feet?
