This site show speaker data for about 50 speakers, including 5 from Axiom. NRC of Canada facilities were used to generate the data. In terms of frequency response and distortion, the Energy Connoisseur C-9 and Paradigm Reference Studio 100 v.3 were most impressive, outclassing the M80 from Axiom. Now I am having second thoughts about ordering the M60. Unfortunately, the M60 was not among the speakers that were measured.
