Steady rhythmic thumping from a ProMedia 2.1 BT subwoofer

Recommended Posts

Good Evening,

 

I recently purchased a ProMedia 2.1 BT computer speaker system direct from Klipsch and I noticed almost immediately that the sub-woofer has a constant, steady, rhythmic thump approximately 1 second apart regardless of if sound is playing through the system or not.  I have gone to the troubleshooting website and uninstalled and reinstalled my audio drivers (as recommended), as well as turning off all digital outputs (as recommended).  I have also plugged the unit into multiple power outlets, with both power-filtering/regulating line protectors and directly into the wall outlets.  The only time the thumping goes away is when I unhook the pre-amp control cable from the control unit to the sub-woofer. 

 

I am presuming that I have a bad control module but I was just curious if anyone else has had this type of issue. I have also submitted a trouble ticket to Klipsch directly.  

 

Thank you in advance for you help!

Sounds like the amp.  The Klipsch trouble ticket should guide you through the repair/replacement process.

Thanks!

 

Still waiting to hear back from the Klipsch folks. Hopefully they get back to me soon.
