I was really interested in this system, but don't have the power to drive it, and the center channel speaker is too wide for my HT cabinet.
After looking I found that I could get the MMG for the front channel for a little more than the MMGW and the response goes down to 50 Hz. Then use the MMGW or even the MC1 for the rears. I thought this was a better set-up, even if a little more expensive.
