Dear Digital, Matt and spbob have good insight as to your question. But don't just think that the speakers mean all, even if you went with the 60s. Your amp. is most important, some say there's no difference in competent amps. but a decent external with more power eg.400 plus watt will bring out more life than ever on Axioms they really love power!!!
Witch I think is kind of in the design as the president of Axiom enjoys really loud audio as you will find reference to if you search these forums.
P.S. I vote for the M80 I've owned mine for a month and think they're Awesome. But the best thing I did was get a PRO power amp. It was an instant feeling of WOW they opened right up.
