Hi,
Ian will be doing some measurements with our M80 in Axiom's large anechoic chamber, so I should have some data for you in a day or so.
Of the Axiom line, the M80, M60, M22 and M2 are very linear, and the M60 and M80 would have very low distortion (under 2%) in the 94 dB SPL range.
My expertise is in domestic hi-fi speakers, not concert and pro sound reinforcement. Some well-known past brands include Meyer and JBL, and there may be new players on the block. Axiom does have a consultant on digital design who used to do the live on-tour concert mixes and setups for Led Zeppelin way back when, so I'll see if I can get some feedback from him.
Regards,
