[QUOTE="Tom Manchester, post: 81737, member: 82"] Re: strange subwoofer thingie I've had a few drivers for whatever reason* the voice coil gets partially jammed in the gap and a strong signal is enough to dislodge it temporarily. Usually when you run a low level signal through it you get nothing but midrange content because of the limited excursion and when it breaks free the bass content comes back but with a lot of other mechanical clicks and pops. *(in one case it was a JBL driver where the foam vent filter had disintegrated and the particles melted into the voice coil gap melting and became a thick syrupy mess In another case it was a B&C driver with a cracked magnet that shifted and was pinching the voice coil in place. ) [/QUOTE]
