I just got some new speakers, and while listening to "Sposa son disprezzata" off of The Sopranos soundtrack I hear crackling coming from my right speaker. The crackling is coming from the tweeter. So I swap speakers, keeping all other connections the same. I hear crackling from the same speaker, which I've now moved to the left. Just to make sure I'm not crazy I swap them back and the crackling moves correspondingly. Is this a busted tweeter, a tweeter cover that's too tight to where the tweeter is bumping up against it, or maybe an issue that'll be fixed with break-in?
