I will be used M3's for back surrounds with QS 8's as side surrounds too. I actually listened to John and took his advice on this set up. If it doesn't work, I'll just blame him. But even if it doesn't, I've got lots of rooms for the M3's to reside.

If you think about it though, I don't think you'd actually have to be in the sweet spot Randy. Aren't all DVDs in 5.1 or 6.1 anyway? So no matter what, you are going to get the same sound from both back speakers wouldn't you??
