I vote for either no 1 or no 2!!!(naturally)

I have M50s and simply love them; M50s are good,comfortable,pleasant all around speakers great for Music, TV, and Movies. Nuff Said!

That said, for mostly movies; probably no 3. M60s live for action movies and serious music listening. If cost isn't a major issue, then the VP150 and qs8s' is probably a better bet yet, considering the size of your room.
