G'day there,

I was playing some Frequency sweeps on the weekend and when it got down to 15 - 5hz 1 of the M80 woofers made a ticking sound when moving in and out confused. Just wondering what that could be and if there's a problem with the speaker? So on that note i checked the other M80 and VP180 by pushing the cone lightly and found that a couple mid range speakers made a scraping type sound eek and wondering also what that could be and if there's something wrong with the speaker. With them making that sound will that do damage to the speaker because i cant hear it from my seating position but would it effect sound quality? Hope you can help,

Cheers.
