Troy, after reading that thread I'm in general agreement with most of the points made in the post by Jan Vigne. My own listening is probably about 99/1 music/movie and getting the mid-range "right" is especially crucial for music. The M22s are outstanding in this respect and it should be kept in mind that they have two 5 1/4" drivers handling it, as does the M80. The M60, with the larger enclosure, has one of the 5 1/4" drivers. As a result, the M22 has the capacity to "play louder" than the M60 in this key range and has slightly higher sensitivity there. Sensitivity is generally measured in the mid-range(the NRC spec is typical and is from 300Hz to 3000Hz)and the Axiom spec is 87dB for the M60 and 89dB for the M22. Since the size of the enclosure in itself has no direct effect on mid-range efficiency, as expected the two drivers vs one which the M22 has give it the edge there.
So yes, a larger enclosure can be tuned for lower and louder bass response, but has no advantage in the mid-range and treble with other drivers being the same, and may be at some disadvantage, as was pointed out by Vigne.
