I would make sure a pair wasn't available first. Used, new, repaired. I would make sure there wasn't an XO problem. Both were wiped out behind shipping? NO!
Maybe one (I'd doubt it) oscillation from a power amp is a lot more likely.. AND I would be looking real close at the tweeter XO circuit.. NOW not when you get a tweeter. Don't blow up another set behind blown caps, too.
Best to stay out of trouble, instead of get out of trouble..
