kibe, M22's are definitely too small.

I would totally agree with Spiffnme on this one.

This is a seriously HUGE room by any account and needs a large speaker to fill it. Although the M60's will play very loud and cleanly this is the kind of room the M80's were designed for. The M60's are for medium to large rooms and I think in this room even the M60's will be approaching their upper limit. I'd definitely want some reserve power for that room and I don't think the M60's will have it. Your neighbours room is Xtra Large and that's why I'd say go for the M80's. If you're neighbour can't have both the M80's and a sub then just put off the sub for a while. My reckonig is get the M80's no question. Then when his budget allows get a big ass sub. He doesn't want to be dissapointed again. The M80's do very well in the base department and should be satisfying enough for your neighbour until he can get a sub.

I'd also suggest talking with the folks at Axiom, they should definitely beable to tell you if the M60's are even worth considering.

Good Luck, Jag
