Just curious about the yammie receivers. Can they handle 4 ohms well?
Any of their receivers?
I'm wondering if the 4600 will be able to as well, but we'll have to see I guess.

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.

Look at their power output into 4 ohms and 8 ohms. Also look at the damping factor.
That damping factor is almost tubelike(read: bad, when talking output impedance), and the output should at worst only go up a few watts: the fact that it goes down is evidence of either current limiting or inadequate amps. The receiver is over $1000, in which case you'd be much better off with a refurbushed 50 lbs NAD or HK which can handle 4 ohms no problem.

Wow Thasp... I had no idea that Yamaha was really that bad with 4 Ohm loads. I wish I still had my RX-Z1 to try some 4 ohm speakers.

Is that one of their flagship ones?
What I've noticed is that flagship receivers usually measure/perform as well as seperates, but cost much more. The RX-Z1 would probably do 4 ohm loads no problem since cost wasn't an issue.

It was their flagship a few years ago... before the RX-Z9 came out and destroyed it. At least it retailed for much less than the Z9 even when I bought it.
