Daffypuck Posted July 26, 2015 Share Posted July 26, 2015 Well, I think Ive gone and abused my speakers and blown the tweeters. I usually never turn up beyond reference level, but did while hosting a party. I think the source, an iPhone, had more to do with it than anything. My question, is how should I go about troubleshooting the speaker to determine if I blew the tweets, damaged the mids or woofers, or if I damaged the crossovers or any other part of the speaker. Also, can anyone provide a link to a reputable buyer for new tweets? Thanks. 1 Quote Link to comment Share on other sites More sharing options...
Guest thesloth Posted July 26, 2015 Share Posted July 26, 2015 (edited) What speakers are they? I assume from your post you have a multi-way speaker with multiple drivers so there is most likely a crossover network. You will have to look to where each driver connects to the crossover network and disconnect them. Then measure DC resistance with a multi meter. You want continuity of anywhere between 4 and 16 ohms depending on the driver. An open cicuit is a bad thing and means you most likely fried the voice coil.

Daffypuck Posted July 26, 2015 Author Share Posted July 26, 2015 They are RF82 II Im trying to remove the tweeters to test, but it looks like Ill have to remove the top woofer to disconnect the tweets. Ive looked around and cant seem to find a thread that talks about this process.Theres not enough free play in the wiring to pull the tweeter horn far enough out to see how it connects.

Guest thesloth Posted July 26, 2015 Share Posted July 26, 2015 (edited) Maybe you don't have to remove the tweeter? Check the jumper in the back where the binding posts are, maybe it's loose? If you can check behind the binding post, there looks like there are four screws that hold the cup in. The wires from the tweeter probably travel down to there.

Daffypuck Posted July 26, 2015 Author Share Posted July 26, 2015 (edited) I got it out and confirmed my suspicions, the tweet is blown. I tested the top woofer and got a reading of 6.3 OHMs. Im just wondering if I couldve damaged anything else. Should I test the crossovers? Or anything else for that matter and if so, what should I look for? Also, out of curiosity, how do these types of speakers work? Both woofers seem to be the exact same thing, yet one is a mid and the other the lower freqs. Are they just designed that way to have a broader frequency range? Off the top of my head I cant recall how low these are rated, but Im guessing somewhere around 35-39hz. Who is a reputable Klipsch parts dealer?

Guest thesloth Posted July 26, 2015 Share Posted July 26, 2015 What voltage rating do the capacitors in the crossover have? What power amp where you using? How many watts? The speakers are rated for 150 watts correct? That means they could have gotten away with using 50v caps. If they are 50v caps then a 300 watt amp (into 8 ohms) would be pushing the limits: 300*8=2400 square root of 2400 is 48.9Vrms or 68.5V peak. If they are 100v caps I would think they would be fine unless you were cranking a 600 watt amp. Quote Link to comment Share on other sites More sharing options...
Daffypuck Posted July 26, 2015 Author Share Posted July 26, 2015 My system is a Denon 4311 coupled with an Emotiva XPA-5 (200w) amp. I have cranked in the past, but I really pushed it this timme. Drinking and a remote dont mix. From sources Ive read, an iPod or iPhone source type can deliver subpar source material which can exacerbate loud listening. I remember taking a sound reading from about 9 ft away and I was hitting around 107-110db with an occasional peak of 112db. It was stupid loud. I really question if I should even use the Emotiva in my setup. The 4311 is a pretty stout receiver. I think its amps are 140w each. Quote Link to comment Share on other sites More sharing options...
Guest thesloth Posted July 26, 2015 Share Posted July 26, 2015 You probably damaged it from too much power but it might be a good idea to have someone with an oscilloscope check the amp for instability. High frequency oscillation can burn up tweeters. Quote Link to comment Share on other sites More sharing options...
Daffypuck Posted July 26, 2015 Author Share Posted July 26, 2015 I took the crossover off the back and it looks like it has 100v caps on it. Quote Link to comment Share on other sites More sharing options...

Daffypuck Posted July 26, 2015 Author Share Posted July 26, 2015 (edited) I know, I did something I havent done in 20 years. I really, really pushed them. To be honest, I think they couldve handled it with better source material. Had to hook an old pair of Cerwin Vega DX series until I repair the 82's. But, I was always under the impression that if ya wanna listen to music loud, get some high sensitivity speakers and roll with it. Aparently I rolled a bit to far.

thebes Posted July 29, 2015 Share Posted July 29, 2015 The parts department at Klipsch can set you up with replacement tweeters. Bob Crites is another source. Chances are that's all you've damaged. 1 Quote Link to comment Share on other sites More sharing options...
Daffypuck Posted August 1, 2015 Author Share Posted August 1, 2015 Does a blown tweet magnet or any of the other parts have any value or use? Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted August 1, 2015 Share Posted August 1, 2015 All tweeters are prone to damage due to their inherent defect, man! Quote Link to comment Share on other sites More sharing options...
babadono Posted August 1, 2015 Share Posted August 1, 2015 (edited) Does a blown tweet magnet or any of the other parts have any value or use? It's the voice coil/horn diaphargm wire that blows, The magnet is fine probably. I don't know if replacement coils/diaphragms are available for Rf 82 tweeters. You might have to buy complete new tweeters. Call Klipsch tech support as thebes suggested. I'm sure you're not the first person that over did it a wee bit. And to answer your question they make nice paperweights And Welcome to the Forum Edited August 1, 2015 by babadono Quote Link to comment Share on other sites More sharing options...
