Yep Ryan.  That was my gig. 

It was caused by a recent recone failure.  The surround partially tore, and the voice coil jumped the gap.  The result was all that energy going to the voice coil turned into heat.  The cone merely smoldered a bit.  What actually caught on fire was the foam glued to the steel grill of the cabinet.

I personally witnessed several speaker fires back in the 70's. Crown DC300's were notorious for dumping DC into the outputs, as were Phase Linear and early BGW's I remember one speactacular event in a club (a disco) with GLI speakers powered by BGW 750's. The DJ decided to fix the system (it wasn't loud enough) by removing the crossovers from the boxes and tying the amplifier out[puts together (NOT bridged, just hardwired). The first night after his modifications I was running the lights and suddenly saw a bouncer running for the dance floor with a fire extinguisher. At that same moment we all smelled the burning stench, and I ran down to the dance floor. Speakers were 15' in the air, so the bouncer was spraying foam all over the ceiling, lights, and patrons. They got the fires out (there were 3) and continued thru the night at a greatly reduced volume. The DJ was not seen again in that club.

I'm a DJ who knows sound fairly well, but I'm kind of an exception to the rule. I know maybe two other DJ's who have some basic knowledge, and the others I know, I would not allow to touch any of my gear  ;D
