Klipsch Heresy 2 has lower volume than the companion speaker. Checked all cables/new amp

[SeanHiFi]

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.

Welcome! Have you done any troubleshooting?

@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 .

What is DCR in Inductors and how does it affect your Circuit Design (circuitdigest.com)

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.

Yes, what amp do you have, btw?

[OO1]

 remove the woofer screws ,  set  the Ohmmeter  dial on Ohms and take a reading of all  3 drivers  + ,check the internal wiring and connectors 

 

[HiFi Heaven]

"a  very  low  or 0 reading would indicate"  A SHORT, NOT AN OPEN!

 

[SeanHiFi]

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? 

 

[Marvel]

Possible, yes.

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.)
