What makes the sound "bigger?" Is it the presence of the mid bass? The drivers are the same on the m2 and m22 as the m60 except for the 6.5s.

Oh, also, my room is 15x15 with a 12ft vaulted ceiling with the sitting postion at 10ft.

I'm trying to save some money by not going with full size speakers. Also, the m60's look big in my room. I can see the full depth of the left speaker from the kitchen and it spoils the room a little bit.

I am willing to give up a small amount of musical ability for this change, but I really don't want too much of a change for 5.1
