pete1729 Posted May 20, 2014 Share Posted May 20, 2014 I have recently acquired a pair of Cornwall I's from the mid 80's. They have the B3 crossover and according to Klipschcorner.com should have K33E woofer / K52K mid / K77M tweeter. Instead what they have for tweeters is this: One EV T35 and one K77M, both are dead, they pass no signal at all. I opened up the T35 and the voice coil was separated. Furthermore, with respect to the midrange what I have is this: One K52K and one K55M. Both are functional but sound different, as you mIght Imagine. The woofers are K33E and are fine except for some candle wax in the pleats of one of them. Obviously the tweeters should be replaced with Crites CT 125's, What should I do about the Squawkers? There aren't a whole lot of K52K's out there, the last one I can find that sold on ebay was in 2011. The K55M is just wrong from what I've read. I'd like them to match at the very least. I'd like to retain the original crossovers for the most part but I realize that may be impossible. I'd recap them, of course. What do you suggest as a program for getting the most out of them?

CECAA850 Posted May 20, 2014 Share Posted May 20, 2014 It never ceases to amaze me what you'll find once you open the cabinets after a purchase. I bought a pair of KP-301 II's with mismatched crossovers and mismatched tweeter diaphragms. A pair of Cornscalas I bought had mis-wired crossovers and when the new larger horns were installed in the cabinets, the speaker grill boards were never cut. In essence, most of the new horns output was hitting a solid piece of the grill board. Good luck with your hunt. Quote Link to comment Share on other sites More sharing options...
longdrive03 Posted May 20, 2014 Share Posted May 20, 2014 Pete, there are two K-52-H drivers on ebay now at $85 each. http://www.ebay.com/itm/Klipsch-K-52-H-Repacement-Driver-/290814688346?pt=US_Speaker_Parts_Components&hash=item43b5e7fc5a Don't know that this is what you need but at least they would match.

pete1729 Posted May 20, 2014 Author Share Posted May 20, 2014 Thanks everybody. Pete, there are two K-52-H drivers on ebay now at $85 each.http://www.ebay.com/itm/Klipsch-K-52-H-Repacement-Driver-/290814688346?pt=US_Speaker_Parts_Components&hash=item43b5e7fc5aDon't know that this is what you need but at least they would match. Hope this helps The K52H drivers would be an excellent option. The K52H driver and B3 crossover is supposed to be a superior combination. I have the B3 crossover in my examples another 55 would be fine im sure The one I have in mine is a 55M which sounds way rolled off but that's with no tweeter.

Schu Posted May 20, 2014 Share Posted May 20, 2014 (edited) Rolled off might be actually better as long as there is nothing else wrong. Edited May 20, 2014 by Schu Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted May 20, 2014 Share Posted May 20, 2014 Correct me if i'm wrong but the 55 is the better driver right? Quote Link to comment Share on other sites More sharing options...
USNRET Posted May 20, 2014 Share Posted May 20, 2014 If you decide to use another K-55M and you need one let me know. Removed from my center Belle and checks good. Quote Link to comment Share on other sites More sharing options...

A couple of Bobs tweeters and this would get you up and running with matched parts. Quote Link to comment Share on other sites More sharing options...
pete1729 Posted May 20, 2014 Author Share Posted May 20, 2014 USNRET I might take you up on that. If I end up with a pair of new drivers I'll offer you my orphan. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted May 21, 2014 Share Posted May 21, 2014 How did you cut the holes in the grills? I was actually proud of how they came out. First I peeled back the top half of the grill cloth and put a pencil outline of the shape they needed to be. I took one an oscillating cutter and cut to within a quarter inch of my pencil outline. Once that was done I built a frame out of scrap wood that was the size of the opening and clamped it to the grill board. I put a flush (tracer) bit on my router and traced the frame I built. The exposed cut edges got colored in with a sharpie. The grill cloth got glued back on with contact adhesive. Quote Link to comment Share on other sites More sharing options...

Frzninvt Posted May 21, 2014 Share Posted May 21, 2014 The B3 network is designed for the K52K it will not sound right with the K55M or V without modification. Replace the K55M with a K52 and sell the M to cover the replacement costs. You should have the K-77M tweeters in them. Bob's tweeters will make them sound different, 1 Quote Link to comment Share on other sites More sharing options...
