So I picked up 2 sets of KLH 23's the other day for next to nothing. I hear these are pretty reputable speakers. I have been reading much information as to the drivers because I need to replace one tweeter and one woofer. Is it a FACT the the tweeters in the model 5,6,17,20,23 are all the same and is it a FACT that the model 23 and model 5 share the same woofer? There seems to be lots of debate on this issue. The tweeter is no good and the woofer has a cut lead wire. Thanks a bunch...
