Unless you want to drive the Axioms with 1,000 wpc amps outdoors fully cranked, don't worry about power handling, especially on the M60s and M80s. More likely, you will damage your speakers by pushing a smaller amp until it goes into clipping, sending massive distortion to the speakers.
My Axioms are the best speaker I have owned in about 20 years of the hobby. I love them compared to the Rocket 750s. They are also better than Klipsch Forte IIs (which used to be my favorites), my EPIs (very good speakers), My Advents, Pinnacles, Bostons, and my buddy's Infinity speakers.
That being said, I still opted for an SVS sub to go with my Epic 80 system.
