Blaster, welcome. When supported by good subs such as you have the M22s have plenty of dynamic capability above the low bass. The one change that I'd suggest in what you propose is to use a vertical M22 for the center speaker so as to have M22s across the front. You have plenty of space under the screen to place it. This should make for excellent sound with your QS surrounds.

Enjoy the music, not the equipment.
