Speaker problem.

I bought some polk monitor 30s a while back, and now that I've got room for full surround, I noticed that one of the speakers sounds different than the others.

It sounds "muddy" as if the tweeter isn't getting power, but I've never had any of them play very loud. Is this a common type of defect in speakers?

Blown tweeter? If so, Polk might replace it. It's not unheard of.lowe0

First thing I did was swap it with a spare and I instantly noticed the difference.

I've never driven the speakers hard so I couldn't have blown the tweeter. A defective crossover sounds like it could be the issue.

Thanks.
