Am close to the point of ordering a system. I talked to Yamaha, I have a RXV1500 and they have told me that the reciever is not recommended to us at 4 ohms. That moved me to consider M60 for my fronts. Can anyone comment on the M80's using Yamaha recievers? Tks

Some Yammy users will answer.
The M80 are an easy 4 ohm load because they are very efficient.
The best thing is you can try them. You get 30 days to test them out.

I have a rx-v4600. It handles the load fine. ALthough I do have the internal fan on all the time and my amp is not inside a cabinet and in it's own large closet. Heat is just not an issue for me even after 6 hours or so.
I do not think I would recommend the 1500 for the 80's. It would make a good preamp though and get an power amp to do the 80's.

Bob, typically company representatives, primarily for legal liability reasons, won't recommend using equipment not specifically UL listed at 4 ohms with 4 ohm speakers. Nevertheless, Yamaha and other similar receivers have often been used successfully in that way with M80s and other 4 ohm speakers. Also, as Doug mentioned, the M80s are a relatively easy 4 ohm load because of slightly better than average sensitivity and a relatively flat impedance curve.

Enjoy the music, not the equipment.

Ferguson, I have been driving the Epic 80/600 system with a HTR-5660 for over 2 years now with no issues. It does run warm/hot, but has never shut down. The key to your happiness is will be how loud you like to listen, and how big the room is.
At the last house, the system was in a 2300^3ft room (16x18), and the Yamaha was more than adequate. In this house, the system has to fill 10,000^3ft, and the Yammi just isn't cutting it. As the volume goes up, things fall apart rather quickly. The highs get very harsh and the mid bass gets sloppy. Luckily it has pre-outs, so adding an amp is very easy.

Hi Ferguson,
While there is lots of good advice in this thread, especially re. your room size and how loud you want to listen to the M80s, past Axiom customer experience with Yamahas and Onkyos with the M80s suggests that, apart from a few models, those brands are not good choices for 4-ohm loads.
That's the reason Axiom generally recommends Denon, H/K, Rotel, Outlaw and NAD, because they have not had issues with overheating, current limiting or shut-down with the M80s, so long as they aren't used in enormous rooms at extremely loud levels, in which case you'd want to consider big separate power amplifiers of 200 to 300 watts per channel.
