Just ordered my Axiom's today (M60ti's, QS8's, EP350, VP150 and VP100) and I'm extremely excited about the purchase. However, I am left pondering one decision that I did not make. My receiver which is a Yamaha RX-Z1, which can utilize effect speakers for their DSP's. I was debating the purchase of a couple of M2i's for this purpose but put off the purchase (maybe a little overkill). I know that I will be extremely pleased with my 6.1 setup but pose this question to the masses if anyone is utilizing the effects speakers with their Yamaha's could give me a little feedback.

I purchased a VP100 for my rear center, I noticed that not many people seem to recommend this approach but I only have about 8" of usable wall space to mount the speaker and I thought that the rear center was primarily used for dialog anyway that the VP100 would be perfect. Anybody else using a VP100 or VP150 for their rear center?
