nmorris43 Posted August 21, 2021 Share Posted August 21, 2021 Ok everyone.... I was listening to my ,new to me, CF4's and i was not hearing what most CF4 owners say is very good sound reproduction. So, i decided after emailing with Mike Crite, to send the crossovers to him to rebuild. I proceeded to open up the CF4's and found that my tweeters do not have the K-63-KN drivers on them (see pics). No wonder the sound was way off from what i would expect them to have. I know that original K-63-KN drivers are almost impossible to find.I have heard that Electro Voice DH1506 drivers work well in this situation. Does anyone have any experience with those EV drivers? Or does anyone have any other suggestions to create suitable audio output? I plan on keeping these CF4's if i can get the sound to meet their potential so being "all original" is not a huge issue for me understanding the driver availability issue. Thanks for any help, Neal Quote Link to comment Share on other sites More sharing options...
absolve2525 Posted August 21, 2021 Share Posted August 21, 2021 Wow yikes! Sorry, that's a cheap piezo tweeter where your stock driver should be. Can you contact the seller? Quote Link to comment Share on other sites More sharing options...

Can you contact the seller? I have talked with him. He found them and turned them pretty quickly. I don't think he knew what the drivers were. I also didn't pay full value knowing I might need to do some upgrades. 2 Quote Link to comment Share on other sites More sharing options...

Check with Crites meanwhile. He may know a source. Crites know Klipsch well. Quote Link to comment Share on other sites More sharing options...

Sorry you did not get many or much response on the Epic thread. Would do a read on the last 10 or so pages on that thread. There was even a bit about the C-2 horn driver as being a close fit, etc... Cannot recall the date. Also a search using the forums search using the EV driver model should yield results. Quote Link to comment Share on other sites More sharing options...
