Axiom Home Page Forums General Discussion Home Theater M80 vs M60 with Onkyo reciever

Hey guys, enjoy reading all your comments, I'm deciding what system I want to go with, I've auditioned Boston VR3's to Klipsch RF82 for my mains, but now am reading about the M60's or M80's from Axiom and am very intrigued and am pretty set on buying through Axiom. The question is, I have an Onkyo txsr575 7.1 reciever rated at 80 watts/channel. Which speaker would I most benefit from, the M80 or the M60. I know the M80 is a 4 speaker load whereas the 60 is an 8. Should I try to sell this reciever and get a new one? I really like the Onkyo, was this a bad choice in others opinions? Just curious what creative options there are to ponder... thanx
