Hi,

I have owned my M80's now for about six months and still love them. The only thing I don't like about them is that they don't like playing low quality audio signals like some avi movies. Occasionally I can hear crackling from the speakers, which I assume is just an accurate reproduction of the low quality audio signal coming from the source. My friend has some lower quality speakers that sound much better without the crackling when I play the same low quality audio signal through. Does this sound typical?

My other question was in relation to the power handling capacity of the M80's. I have heard that the M80's can handle 700 watts RMS running continously. I find this hard to imagine as I can see significant speaker cone excursion while only running about 140 watts RMS through them. It looks like the speakers are running close to maximum capacity even at only 140 watts RMS. Has anyone ran their own tests on the M80's to see their true capabilities.

According to Alan : "Driver destruction occurs at 1200 watts."

I see no reason to doubt him.

But to answer your question, due to many reasons; I haven't.

Axiom speakers are accurate and detailed.

That means you're going to hear every little detail of a recording, including flaws. If you play lousy media, it's going to expose it. And if you play really good media, it'll sound amazing.

There's no such thing as a speaker that does both, as those two goals oppose each other.

Grant - 140 wpc definitely is not anywhere near the max capacity of the M80s. Several forum members here have put much more power than that through them through their separate amplifiers (though for most people it's rare to do so as you really have to be playing them very loudly).

One thing to keep in mind, though, is that M80s handling very large amounts of power are running "flat"... just boosting the bass by, say 3dB will push the woofers twice as hard.

For best performance with huge gobs of power, I would certainly be rolling off the lows below 40Hz or so and let a sub handle the LFE stuff.

To answer your questions;

1) Yes, crap will sound like crap on good speakers.

2) The 80's can handle peaks exceeding 1,000+ watts and RMS of 700 watts for 24hr/day for 2 wks in lab tests.

So, it is really not hard to believe when it is fact. \:\)

“The 80's can handle peaks exceeding 1,000+ watts and RMS of 700 watts for 24hr/day for 2 wks in lab tests.”

This can’t be full bandwidth, 20Hz – 20 KHz, no way, I don’t care what the manufacture says. I’ve heard of drivers absorbing this kind of power in pulse tests but never on a long term basis.

Respectfully, who cares, nobody could stand the racket anyways!!

To quote Alan Lofft:
http://www.axiomaudio.com/boards/ubbthreads.php?ubb=showflat&Number=229287#Post229287

"Under those conditions, the M80s sustain up to 800 watts dynamic peaks with no damage. Driver destruction occurs at 1200 watts."
The operative words being "dynamic" and "peaks".

Here is the link to the page where Axiom states 700W

“The M80s were tested with this music for 100 hours at 700 Watts continuous input power, with peaks of 1000 Watts!”

Music is dynamic (even Slayer’s material I suspect) so while I can’t deny Axiom made the claim; I am suspicious of the claim.
(too many variables not detailed)

Again, no one could stand the din anyway so why cares. Really all it proves, if it’s indeed accurate, is that they handle prodigious amount of power for which the average individual sitting in their average living space (HT) will never require.
I couldn’t listen to Slayer at 1 watt let alone 700 watts.
