Axiom Home Page Forums General Discussion Advice from Axiom Owners M80's and Optimum 4ohm Receivers

I don't know why it is a fallacy to think that to drive a 4 ohm speaker, you need an amplifier specified for driving 4 ohm speakers. Of course, it could be wrong, but I don't see why its a "fallacy".

I've been using an Onkyo receiver TX-NR3008 for 2 years spec'd to deliver 140 watts into 8 ohms, and I've just changed to a Pioneer receiver SC-1522 spec'd to deliver 130 watts into 8 ohms. So I gave up a little power. But driving 3 4 ohm speakers, VP180, M80, M80, the Pioneer is sounding lots better to me.

Maybe it's relevant that the Pioneer has class D amps that are spec'd to drive 4 ohm speakers?
