how did this happen?

yesterday i finished playing a record, and went to lift it up of the platter. as i was doing this, i seemed to feel a static like charge. it didn't seem like much at the time, but within a few seconds i got a buzzing from my amp, and the warning light went on. i quickly turned it off. when i turned it back on, i got only very tinny sound from my speakers. i switched out the amp and put another one in it's place, and got the same sound, leading me to believe it was my speakers that were damaged. i then noticed i could smell a burning type smell from both speakers port holes. so it would seem that i did fry something, probably the woofer. i'm mystified as to how this could have happened. could a static charge from my turntable do this?

it's doubly frustrating because this happened to a temporary pair of speakers that were filling in for my primary's, which are being repaired after being fried in an electrical storm 6 weeks ago.

any thoughts/comments appreciated.
