As far as the room size to small for the M80's, I actually emailed Axiom with the Specs and they suggested the M80's course they also cost more so was that the best choise, I dont know? I just got the thing setup and have had my daughter the last 4 days so I have not cranked the thing to reference volumes yet, thou I did have it pretty loud and it sounded great to me. Im sure the M60's would of done just fine but if you are like me, theres a little voice in the back of my head that would of kept pounding me with the question what if, what if you would of got the M80's, I didnt want to hear that voice so I took the entire plunge
