I've heard before that the Axioms are closer to the Studio line than the Monitor line, but that was back when the v2 Studios were current - and the v3 Studios are reportedly a bit better than the v2's. Based on that and my years with the Studio/60v2, I don't know that an M80 is going to be the equal of a Studio 100v3, but even if it comes out of the comparison reasonably successfully then it would speak well of the Axiom. I know that the M3ti's I'm using as surrounds have more or less held their own in an otherwise all-Studio v2 setup (although I do still have a slight preference for the Studio/ADP's as side surrounds - but the den doesn't offer mounting locations for the ADP's). My guess? If you like the Monitors, then the Axioms would probably also be a very good fit for you.
