My room is only 12 feet wide with the qs8's on the side walls. I was considering 2 m2's as rear surrounds but was thinking that my room is two narrow to really make good use of them. How wide is your room? Also, in a 7.1 setup should you move your qs8's from slightly behind the listening position to right at the side of the listening position to take advantage of the m2's as rear surrounds?
