Axiom Home Page Forums General Discussion Stereo M50 v3: Crackle from lower woofer

I purchased a pair of M50 v3's on Jan.27, and just noticed today that the lower woofer on one of them crackles from time to time.

It seems to crackle at a couple different frequency ranges: mainly kick drums and mid range synths.

I don't have my Onkyo receiver EQ'd at all; its coming out completely flat. I use the speakers primarily for listening to electronica (trance, electro, and dubstep). I have yet to really turn the speakers up high. The highest I've run them is just over conversation level. The crackle is noticeable at all levels though.

Could you guys provide me with some tips to diagnose (and possibly correct) the issue?

Thanks

Mark
