First off I have to say I am very impressed and happy with these M80's. I bought them second hand from a friend. They are the V2's. Amazing soundstage and these are putting to shame a lot of my poorly recorded music that I have been listening to for awhile not realizing how bad it is.

Now to the issue at hand. I have this crispiness/crackling sound(sorry for the non-technical description) coming from pretty much what seems to be the top tweeter. Its like a slight popping type noise. I went ahead and ordered a couple of new tweeters feeling pretty confident that was the issue, in the meantime I swapped out the tweeters from my vp150 in to the m80 to see if that would fix the problem. Well it was still there.

Other things I have tried was to switch the M80 with the issue to the channel and connections of the M80 without any issue and the problem is still there. It doesn't happen all the time, only some songs trigger it, and for the most part the higher the quality the recording is, the less it is there or not there at all.

My setup is an Emotiva XPA-5 and Marantz SR6005 AVR. I am running some older Audyssey equalizer setting from my previous speakers, but I don't think this would cause an issue in just one speaker, I would think it would cause the issue with them all.

Anyways any input is much appreciated. Overall I am really enjoying these, its just when I hear the noise I go looking for it in every recording I listen to.

It could be the crossover or some connection problem in the internal wiring. I suggest calling tech support during business hours. They're better able to help with this kind of troubleshooting.

Thank you for the reply.

I did explain the issue to them when I ordered the tweeters and they were pretty sure it was the tweeter as well. I was worried it could be the crossover. The gentleman I spoke to seems to think if it was a crossover issue I wouldn't be getting any sound or possibly worse issues.

Is that the same speaker or the same channel? If it is the same channel then the problem is not the speaker but the amp or the pre/pro. If it is the same speaker then I would suspect the problem is in the crossover considering you have already swapped the tweeters out.

You really should rerun Audyssey or stop using it if it is setup for you old speakers, as the previous EQ is most likely not really helping the Axiom's sound the best

Sorry about that, it was the same speaker switched to a different channel. Im going to stop running the old setting as well. Been waiting to run the audyssey setup until I position everything the way I want(just moved)

Do your M80's have dual binding posts for bi-amp. If so check that everything is tight back there.

I do have binding posts, i have verified everything is looking good and tight.

Anybody else have any other suggestions, i have wiped out all the old Audyssey settings I had as well.

For example I am listening to Brothers in Arms by Dire Straits and the entire first minute intro of the song the tweeter makes that crackling noise. My other m80 has no crackling. The recording is pretty good quality as well.

probably an internal connection/crossover issue since you have tried different drivers and can recreate.

Well, it seems like if it was the tweeter, you wouldn't have been able to replicate the problem with the tweeter from the VP150.

I'm baffled. But I'm sure that if you enlist Axiom's help and have some patience, you'll get it fixed.
