(Note: the M80 tower's impedance is 4 ohms. Big rooms call for a separate power amplifier for the M80 towers. An A/V receiver rated to drive 4-ohm loads without overheating or shutting down is recommended. Call Axiom for recommended receivers or amplifiers that will drive the 4-ohm M80s.)

Hi,

As per Axiom . . .

What brand of AV receiver should I consider to drive the 4-ohm M80 loudspeakers?
For rooms up to 4,000 cu. ft in volume (length x width x height), Axiom has found that receivers from:

•Denon,
•NAD,
•Outlaw Audio,
•Sherwood Newcastle,
•Harman/Kardon,
•Rotel,
•B&K,
•Pioneer Elite,
•high-end Onkyo ($800 and up)
•and high-end Yamaha ($1000-plus)
are the most stable and will make these speakers sing. Buyers who have "great rooms" or those with cathedral ceilings or who want movie-theater-loud playback levels in such rooms should consider using separate outboard power amplifiers for at least the M80s.

Hi,

Jc, i don't see Emotiva's in your list, which I was considering for m80's. Any known issues with them??

Sarang, I use 3 Emotiva UPA-1's for my M80's & VP180, and have not had any issues. My Integra did a fine job as well which technically JC covered with high end Onkyo.

Emo must have resolved their past problems, but there was a time when they were very iffy driving the easy to drive m80's, rockets, etc. Personally, now that I've owned both, the Outlaws are much better quality/performance, and built right in the US per Outlaw specs is iceing on the cake.

Sarang,
Emotiva is not on the list because of reported issues awhile back. As you will be able to read on the forums, some owners are using Emotiva without any issues.

hmm, wonder if the amp arrived and how good the M80's sound.

Yeah, see this thread:
