Did I smoke my centre channel..??

I was listening to my favourite concert dvd,Stevie Ray Vaughan,and noticed a electrical smell coming from the C.C.
I immediately turned it down,well not immediately I had to put my double rum and coke down first,which is probable why it smoked in the first place.
Tried it again and still same smell.
I am suspecting that I over heated the voice coils or the glue used to wrap the coils.
Took it down to the local "repair shop" and it got a "nothing wrong rating".
Is it possible that even though it was overheated that there is nothing wrong..??

I am suspecting it may sound OK now but its life is very short and it probable would be a good idea to replace entire speaker now.

Please what are your thoughts...???
