MustangChris04 Posted September 30, 2013 Share Posted September 30, 2013 Hello, I have a pair of Epic CF-4 speakers (version 2) and one of the woofers in each speaker seems to be bad. At low frequencies it rattles a lot. I switch the bad woofers to the same cabinet then did a low frequency test from 5hz to 100hz and the good cabinet does not rattle at all and it produces clean bass. The bad one rattles and sounds like a helicopter taking off when doing the bass test. Where can I get a replacement woofer (two of them)? The part # is k-30-kn Thanks, Christopher Quote Link to comment Share on other sites More sharing options...

MustangChris04 Posted October 2, 2013 Author Share Posted October 2, 2013 Thanks for the reply. I called Klipsch and unfortunately they do not have any replacement parts. I guess I am out of luck on this one... Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted October 2, 2013 Moderators Share Posted October 2, 2013 Too bad these are for CF-3's. Save a search on Ebay to alert you for Klipsch CF-4 Woofer. Maybe you will get lucky. Quote Link to comment Share on other sites More sharing options...
Speakmeister Posted October 2, 2013 Share Posted October 2, 2013 The K-31 woofer out of the KLF-30 is close spec wise to the later CF-4 woofer. They can be bought new from klipsch, but you will need to replace a pair at least to sound the same. Also, the 8 ohm Crites woofer would be a suitable replacement.

moray james Posted October 3, 2013 Share Posted October 3, 2013 I would add that if you are going to change out speakers that you should replace all four loudspeakers or you will never achieve good results. My first line of action would be to see if a good re build shop will rebuild your existing drivers. That my prove less expensive and provide the best possible match. Good shops can replace your voice coils for you.Good luck. Best regards Moray James. Quote Link to comment Share on other sites More sharing options...

mathman Posted May 31, 2016 Share Posted May 31, 2016 Hi all, first time poster here! I have been exploring the world of efficient speakers, and last week I stumbled upon a pair of CF-4 at a pretty decent price. The cabinets are in pretty decent shape, with a little touch-up and a new coat of poly I think they will look very nice - they are the black oak finish. Anywho, the tweeters are fine, and so are three of the woofers. But one of the woofers has a seized suspension. The impedance is fine, and it makes noise, but with zero suspension travel it doesn't make much noise. I suspect the motor has somehow shifted, and the coil is pinched, but it's not easy to take these things apart. I am going to take it this weekend to National Speaker in Denver to let them look at it, but I'm not too optimistic. Have Ebay alerts set, and I'm checking Craigslist as well. But, if anyone here has a K-30-KN woofer, I'd love to buy it! Quote Link to comment Share on other sites More sharing options...
