One of my tweeters seems to be in disrepair. I pulled it out and hooked it straight up to the amp and get sound, but very fuzzy sound. The foam and cone appear to be in great condition. Is it blown out? The other one is a fine tweeter, super crisp highs, and cymbals I didn't know even existed on a couple of songs, they're amazing! Do I need to buy a new one or can this one be repaired?
