drawtheline77 Posted March 23, 2009 Share Posted March 23, 2009 Hi, I Have a pair of 1993 Khorns, about 2 months ago I noticed a fuzzy, distorted sound from one of them, It happens usually when playing a cd with piano or keyboard, seems to happen only in that frequency range, I have multiple amps,preamps and sources, as well as other speakers, It is in the Khorn, any ideas??? bad xover etc,thanks Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted March 23, 2009 Share Posted March 23, 2009 Hello Ben, Don't worry everything can be fixed. Before others start recommending a $1000 in crossover upgrades, let's get specific about the actual problem. 1st: Have you done the obvious test? Swap the left and right channels from your amp. Now the left channel from the source - pre-amp - amplifier will now go the right channel and vice verse. Does the problem now go to the other cabinet or does it stay with the same cabinet? 2nd: do you have a voltmeter? 3rd: did party goers from a recent event at your place (or teenagers) play the classic game of "how loud will it go"? Good Luck, -Tom Quote Link to comment Share on other sites More sharing options...
djk Posted March 23, 2009 Share Posted March 23, 2009 After checking out with another amp, check the connections from the top to the woofer bin. The bananas get loose and then it sounds as you described. I suggest cutting them off and using spades. Quote Link to comment Share on other sites More sharing options...
WMcD Posted March 23, 2009 Share Posted March 23, 2009 See if something in the room near the speaker is buzzing. In my experience, piano notes seem to excite brick-a-brack, windows, picture frames. Wm McD Quote Link to comment Share on other sites More sharing options...
consistent Posted March 24, 2009 Share Posted March 24, 2009 Hi, The K55 had a habit of blowing diaphragms - if it is in the upper reaches of a piano. Stick you head against the speaker that is giving you the problem and try to determine which driver may be at fault. If both speakers are casuing you a problem then I would suggest trying different CD players, amps or pre-amps. Good luck Quote Link to comment Share on other sites More sharing options...
djk Posted March 25, 2009 Share Posted March 25, 2009 "The K55 had a habit of blowing diaphragms " Really? That's news to me. From 77~88 I ran the service department for one of the largest Klipsh dealers in the USA. I never once had a blown K55V or K55M. Now I actually replaced some K55M on the newer Klipschorns like this person has, but they were not defective. They had connector problems as I described. I do know someone that actually blew a pair of K55V in the stock LaScala, they were driving into clipping with a 600W/8R amplifier though. So I suppose it IS possible, but not probable. This is the song that did it, at about 3:20 into it: http://music.aol.com/song/frankenstein/137436 (select the last version that is 4:42 long) Quote Link to comment Share on other sites More sharing options...
drawtheline77 Posted March 26, 2009 Author Share Posted March 26, 2009 Hi many thanks for the ideas, will do some serious checking with the info given me, pretty sure it is one speaker, but will isolate, thanks Quote Link to comment Share on other sites More sharing options...
