If you use an M3 for the center and it will not be overpowered by the M50s or the M22s if you adjust your receiver settings accordingly, but it could end up being the limiting factor in your overall output. Though the M3 is shielded it is not designed to be closer than 6" to the television screen, this will be irrelevant if you have a rear projection set. If you were to use the M3 for a center I would not suggest laying it on its side, as you would not have symmetrical off axis performance. The VP150 however is designed to lay flat with the dual tweeter array to the outside, will not be the limiting factor in the overall output, and is shielded to be able to sit directly on top of the TV. I think the best overall arrangement would be the VP150 with the M22s. The center channel is a very important speaker in your home theater system.
