ok I bought a set of m80's last year and love them to death playing flac files through a top end pioneer reciever 110 w a side. I can't kick the sound I once had though with 3 cabinets on each side with 12" woofs a 4 1/2" mid and horn tweeters. i want more dbs but I was set on getting the center channel next to match but think I may want to get a bigger amp first. I listen to stereo 90 percent and watch a lot lot of movies but my centers and midlde room and rears have been destroyed from high volume playing. I would like to know if the m80's can really take 200w plus of power, they move pretty hard with 110w and I don't want to blow them. i have read from axiom that they can but I would like to know what you guys are running for amps before I continue building.

The specs say you can hook up to 400 watts to each M80. Turning up a lower powered amp to distortion levels is what will blow your speakers.

What Brian said.

I've heard M80's used as live band support speakers with hundreds of watts. As long as the power isn't distorted, you won't have a problem except for damaging your hearing.

But you're going to need a lot more power to get a lot louder. Have you considered subwoofer(s) instead?

thanks guys, my next question is how much is too much? I can sell my amp now and get an easy $800. It was 1100 new but I would like to have a killer 7.1 setup down the road so Im thinking a killer 7.1 amp with preouts and a kick ass poweramp to match the m80's
what do you guys think? i have added subs in the past but then the mids and highs get unbalanced imo unless you have a lot of drivers.

How big an area are you trying to fill with sound?

huskeydave i've used a Krell FPB 300CX with a pair of m60's. this amp is capable of over 1200W per channel.... the M80's could take the power as well. Don't sweat the power, if it's clean, your good.... distortion an clipping is what kills drivers, not power....

Dave, there's no question that the M80s can take many hundreds of watts, but that your hearing can't(that may be what's "killer" about what you propose). 200 watts make a bit less than 3dB of difference in maximum loudness compared to 110. You should consider not less than 500 watts to accomplish your purpose.

Incidentally, if the sound levels between subs and speakers are properly calibrated by your receiver, they can't get "unbalanced", and it doesn't depend on the number of drivers.

On another related note, drivers do also have an excursion limit. With enough power the driver cannot push any further outward physically and you will hear something like a banging noise.

If you want stupid volume sound, get the biggest speakers and driver sizes you can (e.g. the 'concert' size speakers), however i've had my M60s hit 106 dB before (around 12' distance) and that is 'stupid' loud.

I've heard M80s hit 120dB+, with Parasound Halo 2 channel amps. Of course, it was a 7.1 setup with 5 M80s, 2 QS8s, and 1 EP600. The owner said that the Outlaw amps he had prior (5 channel+2 channel, I believe) did not work at the volume levels he wanted.
