SeanHiFi Posted January 14, 2023 Share Posted January 14, 2023 Hello, I have a set of Klipsch Heresy 2s. I am getting less sound from one of the speakers. New cables, checked them too, and new AMP. I am on the West Cpoast and there are no nearby repair locations for these. Just wondering if there are any solutions I can complete myself. Can do basic soldering and use a multi-meter.

OO1 Posted January 15, 2023 Share Posted January 15, 2023 @SeanHiFi questions ? 1)- swap the cable around from the speaker that has no issues with the speaker that has a problem . do not change the connections to the amplifier what are the results ? does the same issue remain with the same speaker ? 2)- what is the DCR ? of the.... woofer - midrange and tweeter for the failing speaker , you can compare the results with the 2 nd speaker , - if 1 of the DCR results is much lower , then the corresponding driver has an issue , -if the 6 DCR results are close to identical , the issue is a problem with wiring , a loose connector or a damaged connector , or the crossover .

SeanHiFi Posted January 15, 2023 Author Share Posted January 15, 2023 I have changed cables, put on new high quality connectors on new cable and tested those as well.I have not opened up the speaker box as yet. I will check them again by switching them to the other speaker. Quote Link to comment Share on other sites More sharing options...

OO1 Posted January 15, 2023 Share Posted January 15, 2023 remove the woofer screws , set the Ohmmeter dial on Ohms and take a reading of all 3 drivers + ,check the internal wiring and connectors Quote Link to comment Share on other sites More sharing options...

SeanHiFi Posted January 15, 2023 Author Share Posted January 15, 2023 I will move on to the multimeter and testing the woofer. I have heard wiring can come loose over time, connections can degrade, is this likely? Quote Link to comment Share on other sites More sharing options...

SeanHiFi Posted January 16, 2023 Author Share Posted January 16, 2023 Turns out that I have two issues. A bad left channel on my new Rotel Amp and possible crossover issue with woofer issue on one of the Heresy II's. I hooked up an older Sansui to the speakers and had the same issue(s). Connection cables were all fine. Tries other speakers on the Amp and poor left channel sound/volume. Anyone know of any experts in the SF Bay Area who can work on these speakers? *(Will give it a go if not.) Quote Link to comment Share on other sites More sharing options...
