JerolW Posted May 10, 2007 Share Posted May 10, 2007 Hi everyone. I've been enjoying reading the post for a few weeks now and have finally got the gumption up to post. I'm not new to Klipsch speakers, owning a pair of Cornwalls I purchased in 1976. I've owned Heresys and Khorns in the past, but have never given up on my Cornwalls. Some of the stuff I read I understand, but most of the technical jargon is Way over my head. But I'm catching on. I spoke with Mr. Colter and received interesting info regarding types of Cornwals and a possible Xover replacement from Bob Crites. Here's the question - Is it necessary to replace the Xovers, even though they still sound exceptional? Do they wear out? OK, two questions. Yours Klipschally, Jerol Quote Link to comment Share on other sites More sharing options...
BEC Posted May 10, 2007 Share Posted May 10, 2007 Jerol, Welcome to the forum. You don't have to replace the crossovers, but you should at least replace the capacitors in the crossovers. Yours are over 30 years old and you can really only expect the capacitors to stay good for perhaps 20 years. After that the ESR (Equivalent Series Resistance) becomes large enough to effect the frequencies passed by the capacitors and even effects the impedance of the crossover circuit which moves the crossover points. Also, at some point the old oil filled caps will start to leak and make quite a mess. Bob Crites Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted May 10, 2007 Moderators Share Posted May 10, 2007 I am no expert, but I would say Mr Colter was correct they are 30 years old. Since no one else has answered.........I don't think it's an emergency, but the older they get the further they get from original spec. Someone with some actual experience can give more specific reasons, I have never done it myself, just going by what I have read here 50 times. I don't think it will blow out anything if you don't do it, but from all I have read you will hear a real difference .

lwhaples Posted May 10, 2007 Share Posted May 10, 2007 Welcome to the Forum! My crossover upgrade ,was after owning my Cornwalls for less than two weeks. And that's only because of what I read here, So, be careful. Though I'd never look back! Larry Quote Link to comment Share on other sites More sharing options...
JerolW Posted May 10, 2007 Author Share Posted May 10, 2007 Thanks for the reply and the welcome. Is it an easy procedure to replace capacitors? Is it scewdriver and pliers, or is a soldering iron involved? Where do I get them and what kind?????? jerol Quote Link to comment Share on other sites More sharing options...
BEC Posted May 10, 2007 Share Posted May 10, 2007 Jerol, It does require soldering. I can fix you up with a kit of the caps and mounting pads, or do the rebuild for you if you want. Send me an email. Bob Crites bobcrites@mac.com Quote Link to comment Share on other sites More sharing options...

Moderators dtel Posted May 11, 2007 Moderators Share Posted May 11, 2007 I was wondering if anybody would notice how long it took me, It's not the first time that happened to me. I failed typing in HS [:|] Quote Link to comment Share on other sites More sharing options...
Arky Posted May 11, 2007 Share Posted May 11, 2007 I passed in hs but have forgotten what I learned. I am going to pick up a typing program & re-learn. Jerol: Welcome to the forum! Good luck with Bob's kit, you will like it. Quote Link to comment Share on other sites More sharing options...
dp1954 Posted May 11, 2007 Share Posted May 11, 2007 I own a pair of 75 cornwalls and I replaced the crossovers with new ones from BEC. Even though the corns sounded very good beforehand the upgrade made a very good improvement in overall clarity and soundstage. I really was surprised. When I did the crossover upgrade I also replaced the internal wiring with silver strand wire and I rope caulked the HF and MF horns. My 75s have metal horns and I believe the 76 did also. Not an expensive upgrade, and well worth the bucks.. dave Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted May 11, 2007 Share Posted May 11, 2007 Jerol, Welcome to the forum. Hope you can post your take on the change in sound for your CW's with fresh caps. Quote Link to comment Share on other sites More sharing options...
JerolW Posted May 11, 2007 Author Share Posted May 11, 2007 I'll take photos of the process. Like I said, I've never had a reason to crack the cases, so I don't know whats inside. Hopefully just the stuff that's supposed to be there. Jerol Quote Link to comment Share on other sites More sharing options...
