STV_Keith Posted August 21, 2004 Share Posted August 21, 2004 I managed to blow one of the K-30-KN drivers in my CF-4's, so I called Klipsch and they discontinued that driver. Not only that, there is no superceeded part available either. Now what? Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted August 22, 2004 Share Posted August 22, 2004 Get it reconed. Try Orange County or Simply Speakers on the web one of those places should be able to recone it for you. Quote Link to comment Share on other sites More sharing options...

They were only discontinued 8 years ago - I would be very ANGRY if I'd paid full $2500 retail for the speakers and 7-8 years later couldn't get any factory support for them. I've seen accounts here at the forums of Klipsch owners get parts for far older speakers direct from the factory. Heck, I'd be angry buying them used and having that happen. I'd be looking at my living room full of Klipsch stuff, hearing the Klipsch factory operator saying 'So solly, Charlie!' and thinking "WTF!!!! @#$%!!!" I don't know that re-coning would necessarily help you. As I understand it, re-coning won't help if the voice coil is damaged. I guess it couldn't hurt to get an estimate I'm going to guess(?) that a clipping amplifier damaged the woofer. There's no substitute for a protective circuit like McIntosh's Power Guard. I would NEVER ever buy a solid state amplifier unless it had a similar effective clipping protection - sorry, that means Aragon too I believe! EDIT - Actually, reconing DOES include voice coil replacement/repairs. Looks to be about $100 or less at Simply speakers - http://www.simplyspeakers.com/16reconing.htm - The good news - that's about 1/2 the cost of a new driver - IF they could be obtained. The neodymium drivers were VERY expensive. However, it will take an extra month of down time for the repair to occur. Quote Link to comment Share on other sites More sharing options...
STV_Keith Posted August 24, 2004 Author Share Posted August 24, 2004 Well, I did drive them hard a few times when I got my new amps and bi-amped them. I think I hurt the voice coil in it. Sounds OK until you turn the volume up, then it crackles a little out of one woofer. Thanks for the link, I'll take a look. Quote Link to comment Share on other sites More sharing options...
Cleve Posted August 24, 2004 Share Posted August 24, 2004 Good luck! BTW, it takes a LOT of undistorted power to damage one of those K-30-KN drivers. The speakers are rated for 300 continuous, 1000 peak! I don't know what you're running - there's no system specified in your profile. This is speculation on my part - BUT, the higher the wattage amp, the FASTER it will destroy a driver if clipped. In other words, a 200 watt amp is sending 10 times the current into a speaker than a 20 watt amp. Therefore, once driven to overload, the 200 watt amp can wreck a voice coil ten times faster than the 20 watt. I should get a cheapo pair of used speakers and run some tests to confirm. LOL But the point is, the more powerful the amp, the more vital anti-clipping protection is, I believe. Quote Link to comment Share on other sites More sharing options...
STV_Keith Posted August 24, 2004 Author Share Posted August 24, 2004 I'm running a Yamaha M-65 (which runs the highs) and a Yamaha MX-800 (which runs the lows). They are bi-amped - a nice feature with these speakers. Both amps are rated for 170w/channel with 2.7db headroom at 8ohms. Quote Link to comment Share on other sites More sharing options...
STV_Keith Posted September 3, 2004 Author Share Posted September 3, 2004 Ended up sending the driver to http://www.nealspeakerrepair.com to be fixed. They received it last Friday and called me today to say it was shipping out. I'll let you know how it turned out. Quote Link to comment Share on other sites More sharing options...
michael hurd Posted September 7, 2004 Share Posted September 7, 2004 I didn't see this earlier - I was off the forum for a while. It sounds like the suspension had sagged slighlty, resulting in a slight mis-alignment of the voice coil. I would have unscrewed it, then rotated the woofer 180 degrees, re-installed and see if that had helped the problem. Quote Link to comment Share on other sites More sharing options...
