Welcome Mr.
You should be good to go, the m60's are very easy to drive, and the other Axiom's your looking at, even a bit lower in ohm ratings, should not be a problem. If your receiver has an Ohm selection switch, leave it in the 8ohm position.
One other thing to consider to save a little $$$$, is order from the Factory Outlet from Axiom's Store page. You get 10% of the regular pricing, if you buy 5 or more items, you get another 5%. The Factory Outlet speakers are also brand new, NOT refurbished. Axiom has a high quality control manufacturing process, is there is the slightest blemish or nick, they get sold in the FO. Technically they are the exact same as the regular stock. Most of us will tell you we have never been able to find anything wrong upon a detailed inspection.
good luck on your purchase, I'm sure you'll love them
Randy
