[QUOTE="hispls, post: 8864863, member: 614752"] But they absolutely do, and the wiggle room you have in the magnetic gap is only a few thousandths of an inch tolerance before you wind up in trouble. I personally wouldn't even bother trying to repair a stock speaker at all, but it's quite easy to misalign a coil when repairing/replacing a surround and short of replacing the surround again or pulling it up and re-gluing there's no fix. That said, the coil former may be cracked/bent/damaged somehow and then even if it were aligned true you'd get rubbing and if the triple joint were failing (where the coil former, cone, and spider meet) or if the spider were separating from the frame or tearing that would also cause buzzing at any excursion. It may have been instructional to test the speaker at low volume with the ruined surround removed to see if it weren't something else wrong. [/QUOTE]
