Does anyone have information pertaining to the evolution of the current model of speakers? More specifically, I’m interested to know if the M60s/M80s have evolved over the past few years. Some manufactures change their model numbers when they make enhancements, others simply say version 2, 3, etc. What about Axiom? I’m sure the M60s/M80s have changed since their initial production. But I’m curious to know the truth. Any ideas? Also, just when did the M60s/M80s originally hit the market?

Thanks!
