highfidelity Posted March 10, 2001 Share Posted March 10, 2001 Hello, I finally thought to check the serial #'s on my Cornwalls and they appear to be N's (1977?). They seem to have the metal midrange and tweeter. All good so far. When did Klipsch switch from Alnico to ferrite magnets? I've thought about getting some EV T-35's with Alnico magnets for the tweeters. Anyone ever done that? Thanks. Quote Link to comment Share on other sites More sharing options...
Klipschguy Posted March 29, 2001 Share Posted March 29, 2001 The Alnico tweeters are easily identified by their round magnet. The ceramic "mud" magnets are square. I believe the change was made in late 1979. By the way "mud" refers to the way the slurrie mix looks before it is fired to make the ceramic magnets, not because the drivers are inferior. The ceramic K77-M (mud) is a good tweeter. Klipschguy Quote Link to comment Share on other sites More sharing options...
Klipschguy Posted March 29, 2001 Share Posted March 29, 2001 Also, I think your speakers were made in 1974. Klipschguy Quote Link to comment Share on other sites More sharing options...
Klipschguy Posted April 7, 2001 Share Posted April 7, 2001 Highfidelity, Your Cornwalls were made in 1975, not 1974. Please forgive the previous misinformation. Also, your tweeters are alnico, if their originals. Klipschguy Quote Link to comment Share on other sites More sharing options...
highfidelity Posted April 7, 2001 Author Share Posted April 7, 2001 Thanks for the info. What about the squawkers, would they be alnico? Quote Link to comment Share on other sites More sharing options...
Klipschguy Posted April 7, 2001 Share Posted April 7, 2001 Yes, the K55-V has an alnico magnet. As for your K33-B woofer I'm not really sure. Anyway, your Cornwalls you have a superb compliment of drivers. Also those solid baltic birch plywood cabinets (with walnut veneer on yours?) are first rate. Note: baltic birch plywood is a superior hard wood, nine-ply plywood which doesn't have any voids - outstanding quality, quite expensive. Those Cornwalls you bought are built to last a lifetime. Enjoy. Klipschguy Quote Link to comment Share on other sites More sharing options...
