I agree with what has been said above. But I would move the M22/M2/M3 speakers closer together in the rear, to get them off of the same axis as the left (in the picture) QS8. I like that the QS8s will be in front of the listening position on the couch, but think that moving the left M22 into the center just a few feet more will make the rear surround soudn actually come from the rear, rather than the back left (where you may expect a normal 5.1 surround to go.
