Thanks for all the great ideas! this is very helpful sight.
I forgot to mention before that I am running an Infinity Alpha center with Alantic Technology surrounds. I would really like to go with the floor standing models because my alternative would be to place the M3's or M2's on the top of my entertainment center angled down. The M60 looks like a pretty impressive speaker. I would have to place these directly and the ends of the ET center angled in slightly. Do you think this would be over kill for my room size?
