In a 17x17 room, and I'm gonna guess that your ceilings are 8', that would make your room approx. 2300 cubic ft. The M60's would be more than enough for that room size, and feel the M80's would be too much. My room is also approx. 2300 cubic ft. and I almost went with the M80's until I saw that they were meant for rooms much bigger than mine. Yeah, IMO the M60's would be a better match.
