Soundbar crossover

[ahmad8600]

Hello everyone,


I have a Triad Micro Sat 3.0 soundbar. Last night, after playing music at high volume for about four hours, the sound suddenly cut off. After turning off my receiver and letting it rest for 30 minutes, the sound returned, but it was very faint and distorted.


After researching online and testing both the input and output with a multimeter, I suspect that the crossover capacitors may have dried out. Could someone help me find suitable replacement parts? If you think I might be wrong in my diagnosis, I’d really appreciate any advice on how to properly troubleshoot or fix the issue.


Thank you in advance for your help!

Those are film caps. They don't dry out. I suspect the problem is with the internal amplifier of the soundbar.

Sounds like a receiver issue. Do you have any other speakers to test the receiver?

Yeah after looking at the specs there is no crossover in your sound bar. So it does look like the receiver could be the culprit.

The OP has figured out the left and right woofers have burnt voice coils.
