Next time make sure you get speakers with butyl rubber surrounds. They last considerably longer. As far as the magnet separating from the basket is concerned it was most likely a defective weld. If a metal part cracked defective metallurgy would be to blame. I have never seen or heard of a sub woofer driver doing this never mind a much less stressed mid range driver. This driver was defective from the start. It just took a while for it to fail. I would not blame it on shipping. The weakest part of the speaker is the enclosure. A blow hard enough to do that to the mid range driver would surely damage the enclosure and the speaker would have been bad out of the box not years later.
Blown Mid Driver
Listening to some music yesterday for the first time in 3 months. Didn't sound great. Heard a bit of crackling from the left speaker. Took the grill off to find the 'foam' ring around the mid driver had gone flacid / half of it caved in. Not sure how this could have happened. Tunes always played at a decent volvume, but nothing extreme to cause distortion, no physical abuse, etc. Any thoughts on how/ why this could've happened besides volume? Dynamics of some sort? Age?
