I have m60s for my front, vp150 and 4-qs8s for surrounds. I am looking to move to direct firing and replacing my qs8. What pairs better with m60? m2 or m3? I have 2 pc13ultras for subs. room is 25x17x10 I will probably be doing m2 bookshelves mounted on the ceiling and pointing to the MLA for ceiling atmos.
