Hello..am getting ready to get some new speakers and am interested in the M80 towers. However a new receiver or amp is not in the cards (probably not anyway) and I'm wondering if the Pioneer Elites are powerful enough to drive this speaker. Pioneer doesn't rate them for 4 ohms, but I've read of owners using them to do so w no problem. Anyone have any experience with Pioneer and the Axioms? My unit is a VSX 94TXH, 140w per channel to the fronts at 8 ohms, 180 at 6ohms.
