Thanks Alan,
The reason I was thinking about the M2's instead of another QS4 or two, is because I had to frame around some plumbing on my back wall that effectively lowers my ceiling height about 6 inches (for the last 2 feet of ceiling). No big deal except that if I mounted speakers on the rear wall, they would be around 6 to 8 inches lower than my side surrounds. Will that cause any problems? Sounds like the QSX speakers are pretty versitile. Do you think 3 or 4 QS4's (given the rear wall mounting situation) would sound better than my original plan?
Thanks again for the advice!
Rob
