Hi Jim,
Sorry but couldn't help laughing; same thing happened to me!!!
My speakers in my two channel system have four ports at the back of them. Within days of getting them my five year old put two of them in there (a Jeff Gordon and a Mark Martin we are guessing). At this point they are still in there as I'd have to remove the bottom plinth of the speaker and a whopping great crossover board which I'm relectant to fool with.
No loss on the Jeff Gordon but I'll miss the Mark Martin
