I may have to buy an M2 and try it out as center. I tore out the wall behind my VP100 and looked at the area behind it. There's some room there as it's directly above the furnace (but doesn't heat up). I was thinking about installing a VP180 there sometime in the future, but there's some duct work that would be in the way. Oh, well, an M2 may be a better choice than the vp100, or vp150. I'm going to buy the bookshelf version and wall mount it under the TV. One M2 in Cinnamon Beech with one bracket is $215. Checking budget...can order on 1/14/11. That should quell my upgraditis for a little bit longer.
