Very few receivers ever have 4 ohm listed but most will power them. The M80s are actually very easy to drive, only 1 watt at 1 meter to reach 92-95 db, better than either of the M22, M60.

Again, I suggest ordering both M22 and M60 and try them out for the 30 days then ship back the ones you don't want, this would be the BEST way to find out which works for your particular room and tastes.
