I have a spare Hartke XL series 10 in. woofer. When playing through it at conversational levels, the sound from it is distorted (like the amp is overloading, but it isn't). Gently pushing on the cone with even pressure, there were no rubbing sounds and I couldn't find any damage to the cone, surround, dust cap or spider. One would assume then that the voice coil was damaged and that the speaker is "blown". Since no one sells a recone kit for Hartke aluminum cone speakers (this one is made by Eminence... Spec. No. 10768, built 18th week of 1995), I figured that I might as well have some fun with it. Last night, I disassembled the speaker, carefully removing all of the moving parts as one unit. I found the voice coil to be in pristine condition...no signs of overheating, rubbing, loose windings, etc. Anyone have any idea why a speaker that looks fine and seems fine mechanically, sounds distorted?
