Chiliarches Posted May 25, 2018 Share Posted May 25, 2018 Howdy, all. I am not a very technical person and am unsure how to proceed on solving my speaker problem... I got a pair of (late?) Cornwall I’s on Craigslist last summer and have been loving them! However, one of the speakers has started making a high pitched vibration/buzzing sound on certain frequencies, which seems to come from the midrange horn. I took the back off the speaker and checked to see if all the connections and screws are tight (they are). I am unsure how to further diagnose the problem or what to do about it...it is definitely the speaker. The midrange driver is marked “K-57-K”, and the crossover is marked “B3”, if that helps at all... Thank you!!! Quote Link to comment Share on other sites More sharing options...
ricktate Posted May 25, 2018 Share Posted May 25, 2018 Check the washer on the driver between it and the horn. Then check the screws that hold the horn to the motor board. It can also be the bug screen on the driver. Quote Link to comment Share on other sites More sharing options...
Schu Posted May 25, 2018 Share Posted May 25, 2018 Is it a screeching sound or like distortion... or is it like a rattle or buzzing? Quote Link to comment Share on other sites More sharing options...

Deang Posted May 25, 2018 Share Posted May 25, 2018 Does that combo even use a gasket? Sounds like he needs new diaphragms to me. 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted May 25, 2018 Share Posted May 25, 2018 Dean is right no gaskets in those drivers like the earlier versions here are some available replacement mid diaphragms on eBay: https://www.ebay.com/itm/Klipsch-Factory-Speaker-Midrange-Horn-Driver-Diaphragm-K-59-K-K61-K-62-K-127120/141219105169?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D50544%26meid%3Df00d2cc918cb49598b299803c5e50aea%26pid%3D100005%26rk%3D2%26rkt%3D4%26sd%3D141213577688%26itm%3D141219105169&_trksid=p2047675.c100005.m1851 Quote Link to comment Share on other sites More sharing options...

Deang Posted May 25, 2018 Share Posted May 25, 2018 True. Good advise! 1 Quote Link to comment Share on other sites More sharing options...
Chiliarches Posted May 25, 2018 Author Share Posted May 25, 2018 Thanks for the help!!! Update: I took the horn and driver apart - left the diaphragm on the horn because it was pretty well stuck - but gave everything a good clean (vacuumed from the horn side, used used the sticky end of a post -it-note on the driver magnet, etc)...and that appears to have addressed the problem!!! I am thrilled. That being said, I suppose replacing the diaphragms wouldn't be a bad idea for such an old piece of gear. Are those eBay parts good replacements? 1 Quote Link to comment Share on other sites More sharing options...
oldred Posted May 25, 2018 Share Posted May 25, 2018 I'd probably buy them from Bob....or second choice would be Simply Speakers...... George, Quote Link to comment Share on other sites More sharing options...
geoff. Posted May 26, 2018 Share Posted May 26, 2018 That may be why some drivers have “bug screens”. Something got in the horn and started vibrating at the right frequency? Quote Link to comment Share on other sites More sharing options...

I personally like to update these older speakers with fresh capacitors in the crossovers and titanium tweeter diaphragms at the minimum, new mid diaphragms are a good idea because of age but not sure you'd really notice a difference in sound or not, if nothing else piece of mind knowing that they are new might be worth it. Simplyspeakers sells OEM Klipsch replacement parts so good stuff to go with if Bob Crites is out of stock. Quote Link to comment Share on other sites More sharing options...
