At a viewing distance of 10' 8" from screen to couch, would there be MUCH difference between the VP100 and VP150.
Price is a factor, as well as overkill. Thoughts?
I am looking at the M60's, QS4's. Again room size is only 14 x 13

Davey, if price is a factor a vertical M2 should especially deserve consideration.

I sit less than that distance from my 60's and 150. It isn't overkill in my opinion. I guess it depends on how loud you care to go in normal situations. Also, will this system always be in the 14 X 13 room, or do you plan to move one day?

I sit 8' from my VP150 and I sure wouldn't want it to be any smaller. Movies demand a ton from the center channel.

I totally agree. I sit more like 10' away. I originally bought the VP100 but upgraded because it just sounded a bit thin in my opinion. Some have suggested that the MTM design impacts the clarity. Also the VP150 seems to disperse more with a richer sound.
