Dan, my ear isn't refined as the other listeners on this board, but I just got my system below and I couldn't be happier. My room is a little smaller than yours (11x12) but the wall mounted m2is have no problem at all filling the room with PERFECT sound. I'm sure the bigger speakers would sound just as good or better, but I just didn't have the space. Plus if you can get a whole set instead of just the 3 fronts and the sub. You really can't go wrong with anything from Axiom. Just my .02
