Hi polishfunky1,
The M80s are Axiom's no-compromise top of the line tower speaker, and to address your earlier questions, the M80 is slightly smoother on male and female vocals than the M60s or the M22s and because it has a larger enclosure, the M80 has deeper and more rock-solid lower and upper bass output than the 60, with or without a subwoofer. These differences are not dramatic but they are quite audible on immediate A/B comparisons, which I do at the Axiom plant and at my home (I don't have M60s at my home.)
Moreover, because it uses six drivers per side, the M80s has a musical "ease" at louder listening volumes that is just stunning. Given the size of your room, go with the M80s.
Regards,
Alan
