Klipsch website indicates that the RS-35 speakers have two K-137 tweeters. I have three RS-35 speakers and they all have K-129 tweeters in them. However, they all show signs of being replaced. Most of these tweeters are blown and I need to replace. Anyone know the correct tweeter for these speakers, I find it hard to believe that all six tweeters were replaced with the wrong one, especially since they are from two different sources.
