Klipsch RSIII

I have a pair of RSIIIs for my satellites in my 5.1 system. One of them recently stopped working. It still makes a tiny bit of sound, but not enough to hear. What could be the most likely reason? When running through the setup on my Denon, only one of the tweeters makes any noise at all. Can this be repaired, or should I just break down and buy new satellites?
