Rebel_Girl Posted May 21, 2003 Share Posted May 21, 2003 I have a pair of KG 4 speakers. I believe the tweeters do not work properly How can I check, other than audible, to see if the tweeters r working? As i recall the tweeeters have some type of safety feature that shuts them down when they r over driven. Where can I purchase replacement units?

bkrop Posted May 21, 2003 Share Posted May 21, 2003 Audible is one way, crank up some music in the treble range or a test disc with a sweep wave from 20 to20,000 hz and stick your ear in front of the tweeter and listen... Quote Link to comment Share on other sites More sharing options...
Rebel_Girl Posted May 21, 2003 Author Share Posted May 21, 2003 So, in other words, i cant use a multimeter to check for impedence or resistance changes. i dont have a signal generator, but may be able to find a sweep via digital. thx Quote Link to comment Share on other sites More sharing options...
JohnA Posted May 21, 2003 Share Posted May 21, 2003 You can use a multimeter if you remove each tweeter and test it. A ball park figure would be 6 ohms DCR for a tweeter. If its more than 16 ohms, I'd suspect trouble. Quote Link to comment Share on other sites More sharing options...
AndyKubicki Posted June 4, 2003 Share Posted June 4, 2003 Those tweeters come out fairly easily, so if you're not sure as to where the distortion is occuring, take them out of the cabinet. You can purchase diaphragms at . They will run about $32 each plus shipping. I was lucky that I am within driving distance and they tested the tweeters once removed. BTW, they come with what looks like fiberglass dampening material inside the little dome of the diaphragm. Remove that. I thought it was dampening material and left mine in. It didn't make a difference till it hit just the right frequency and then it distorted ever so slightly. Once I removed the material they play great .

djk Posted June 6, 2003 Share Posted June 6, 2003 OCS is not an authorized Klipsch dealer, that is why they charge so much more than Klipsch does for the replacement diaphragm for the Kg4. Quote Link to comment Share on other sites More sharing options...
AndyKubicki Posted June 6, 2003 Share Posted June 6, 2003 I dunno...I was under the impression ( from what I read other forum members said you can't get those from Klipsch ) they are an authorized Klipsch parts reseller. Correct me if I'm wrong, and if you can get those diaphragms cheaper let us know where...though it's way too late for me... Quote Link to comment Share on other sites More sharing options...
STL Posted June 6, 2003 Share Posted June 6, 2003 I believe a replacement diaphram from Klipsch (via 1-800-KLIPSCH) is only $20. Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted June 11, 2003 Klipsch Employees Share Posted June 11, 2003 A meter will tell you if the voice coil is shorted or open, but that is about it The price is about $20 each for the fix if they are bad If you pull them out and connect the speaker wire from your receiver to the tweeter only, you can tell if they are working right. This can be a bit tricky, but a good test. It sounds like you have a meter. Set it to AC voltage and hook it to the speaker wires of your receiver. Turn the volume up to about 2.83V AC. This will equal about 1 watt. As long as you do not go over that voltage you can send most any signal,(short of pink noise) into the tweeter and not hurt it. When I test tweeters in the lab, I run them with a sine wave sweep of 20 to 20kHz at given voltage. They just dont play blow about 1kHz. I hope this help BTW: It is good to have lady, asking questions on the forum. Welcome! Quote Link to comment Share on other sites More sharing options...
