One of my altos started to sound nasty at low volumes - fine if it was given some welly but not at background levels. So, I investigated & found the woofer was rubbing. Gah. I ordered a replacement & it arrived yesterday. 15 minutes after arriving home the new one was fitted & the old one disemboweled to find the root cause.
What might be clear from the photo is a definite puncture in the voice coil former - horizontally, at about the resting point of the cone. The coil itself looked a teensy bit cooked (slightly discoloured) but otherwise fine. So what had caused the puncture? Oh probably the speaker hitting the ground sideways when it fell from my trolley a while back.
Take good care of your kit folks. I've learned my lesson.
