I've got a pair of KHL Model 6 and one of the tweeters stopped working. Does anyone have any experience with KLH speakers? Should I start with looking for a replacement tweeter or replacing the capacitors and see if that's the issues.
KLH Model 8 - as per title - isn't a speaker, is it? I guess we're talking about the old Model 6 as per post?
You've done well to keep these going for so long. Aren't they over fifty years old? If you still enjoy them and wish to keep using them then I guess repair is required. From what I read, the crossovers are simple so only contain 2 or 3 capacitors. If you have enough knowledge, I'd try to replace the caps first (best replace all in both speakers), because it will likely be cheap - though finding modern equivalents may be problematic. Have you any test gear you could use to check out the caps first? Even simpler to check out the tweeter to see if it has gone open circuit or shorted out.
I'd be really surprised if you can source an original tweeter, if that turns out to be the problem. In that case, your best bet may be to contact speaker repair specialists such as Wilmslow Audio or Falcon Acoustics - both long established, reputable companies. These companies can often suggest equivalent modern replacement parts. No harm in giving them a call.
Thank you sir! I double checked and its actually a Model 6. I'll start with the capacitors and go from there. I'll see if I can do some research online on testing capacitors. Thank you for the references to Wilmslow and Falcon!
