I have decided to try a new center because the vp150's off axis response is terrible in my room. Everyone that sits on the side couches are always saying to "turn it up" or "what did they say". I would like to stick with Axiom but can't fit a vp180. So after lots of reading and asking some questions here I am leaning towards an m2. The off axis response should be better with a vertical design. My only worry is if the little m2 can hold its own with the m80's. Here is the design mod I have come up with. The M2 would be on a litte shelf that would overhang from 1-2 inches. Any other ides would be welcome. Thanks
