Newf,
Generally, no. Although a couple of Axiom customers have had success using a Yamaha A/V receiver to drive 4-ohm M80s, I don't recommend them, and that's based on past experience with M80s and Yamahas.
The only brands of multichannel A/V receivers that we have found to be stable driving M80s in rooms or reasonable size (not huge rooms; for those you'll need a separate power amplifier for the M80s) are Denon, H/K and NAD. I expect the large expensive Rotel would have no problem with 4-ohm loads, but I don't have specific data on it.
All other brands of A/V receivers in our experience (Pioneer, Yamaha, Kenwood, Onkyo, etc.) will go into current limiting, overheat or shut down temporarily if used to drive the M80s.
Regards,
