The M80s will work great in any size room. The room size equation is a matter of esthetics and overkill. Assuming you were not concerned with how much of your room the speaker consumes, then the question comes down to the overkill equation. Since the M80s will play lower and have better dynamics than the M60s, these attributes will remain in any sized room. If the room starts to become quite large then these attributes switch from "good to have" to "must have" in order to fill the room with a reasonable amount of sound, depending of course on your definition of reasonable. So in answer to your question there is no ideal room size for the M80s, just upper end size limitations to each speaker model. In other words at some point the room would get too large even for the M80s, such as an auditorium. On an interesting side note I did a demonstration of surround sound in a room of 100 people using the Epic 80 system with 3 subs not too long ago and the system was able to handle this very well up to what would be considered a medium-high volume level.
