Mojo i too was shocked to read that troy has imaging issue's. My room is 15 x 16 x 8 ish and my M80's image well to my ears. I have ran it sans center channel with impressive results,maybe my brain is just adjusting to poor imaging? I know when my mind gets fixated on what it perceives as a problem i have a hard time letting it go.
Troy if this were something i was dealing with i would go with the M5HP and get some stands that compliment your room and sitting position ,the subs will handle the heavy lifting. I started with M2's and 2 subs and the move to the M80's wasn't as great as one would have expected.
