Oddball44 Posted March 18, 2021 Share Posted March 18, 2021 I just set up my Klipsch speaker system I got from Walmart and although both my left and right speakers work fine, my subwoofer is not working. I have tried reseating the 9 pin serial connection and trying different power outlets as well as ensuring the subwoofer's knob is turned up where it needs to be. I have also tried to see if maybe using the AUX input would show any different results but this has sadly resulted in nothing as well. Does anyone have any suggestions on what's up? 1 Quote Link to comment Share on other sites More sharing options...

cvdisace88 Posted May 19, 2021 Share Posted May 19, 2021 Hi Folks! I was having the same issue and I was able to fix it. Remove all the surrounding screws on the back of the sub's rear plate. That will let you take the whole back piece off with all the boards attached. I noticed the minute I looked at the board that the cable from the sub was unplugged. The connector that clips it to the board is not very strong at all. I reconnected the cable and everything works exactly as it should. Hopefully this helps someone having the issue of the sub not working! Quote Link to comment Share on other sites More sharing options...

Exact same thing here. it's just a 4pin connector. If you've ever plugged a fan into a motherboard it's the same kind of cable. They must bump loose in shipping.

I had a different connector loose, but it was a simple fix with this advice. Quote Link to comment Share on other sites More sharing options...
Ken90 Posted August 1, 2021 Share Posted August 1, 2021 Also had this issue, subwoofer wires were not even inserted into the white plug. Inserted wires into correct pin holes for the white plug and then plugged it in. Unfortunately the connection is so bad and loose I will most likely have to reseat the plug if I ever move the subwoofer. Other than that issue the speaker set is amazing, especially for the recent sale price of $70. If this is a common issue I would imagine a lot of returns will be happening, don't see most consumers taking apart a brand new speaker set to fix this issue. Please remember to unplug the speakers before opening them, totally didn't make this mistake myself and got a nice shock 😅 Quote Link to comment Share on other sites More sharing options...
JohnR1953 Posted March 3, 2022 Share Posted March 3, 2022 LATE reply to this thread - but I found the same problem with a "renewed' set - bass speaker wasn't plugged in at all to circuit board. Plugged back in, and used hot glue on connector to prevent future accidental disconnect. they work GREAT now... Quote Link to comment Share on other sites More sharing options...
Viper_357 Posted September 7, 2022 Share Posted September 7, 2022 Same issue; new system purchased from Klipsch - both speakers work fine - subwoofer "out to lunch", as in "no-sound". Subwoofer initially plugged into Tripp-Lite surge protector - power appears sufficient; re-plugged into different outlet - no change-no sound. LED on control pod is white; instructions indicate the LED is green- power issue or just different color bulb?? Quote Link to comment Share on other sites More sharing options...
TXRunner Posted March 20, 2023 Share Posted March 20, 2023 I had the same issue with the subwoofer, but even out several years from the original post, it is not fixed by Klipsch. I removed the back cover and found the same problem. I don't know how cvdisace88 even knew to do that, but the guy deserves major kudos for figuring out such a simple problem. Fixed it, but disappointed that this is even an issue. Quote Link to comment Share on other sites More sharing options...
DJFullwood Posted July 19, 2023 Share Posted July 19, 2023 (edited) Similar issue, but I don't think it's a loose wire. I'm using a 1/4 inch adapter to plug the headphone jack into an audio device. If it's fully inserted I get both left and right but no sub. If either loosen the jack in the adapter or the adapter in the audio device then I get left speaker and sub, but not right speaker. Any thoughts? I've tried 4 different 1/4 adapters. Everything works fine independent of each other. Headphones work fine into audio device and klipsch works fine plugged into my phone.

the real Duke Spinner Posted July 19, 2023 Share Posted July 19, 2023 I returned my non-working ProMedia prolly 7 times before I gave up. 🙄 Quote Link to comment Share on other sites More sharing options...
Christos O Posted April 6 Share Posted April 6 Hi all, thanks for the tips here. I own 2 units of the Pro Media 2.1 Desktop Speakers with Subwoofer: one at my office, one at home. The sound is amazing. From time to time, on both my units I notice the subwoofer just stops working (even when the subwoofer dial is up) when I haven't done anything to the unit (it just stops working on its own). But then it usually works again after a while. This time, one of my units (home) it just stopped working and I can't get it working after unplugging the power and plugging back in, resetting all the connections, etc. Has anyone else experienced this? The subwoofers both worked when I purchased them (about 2 years ago), but stop working after a while. The speakers work fine, it's just the subwoofer. I will try unscrewing the back plate suggestion to check the connections there since nothing else worked. Thanks! Quote Link to comment Share on other sites More sharing options...
Nehrlich Posted May 28 Share Posted May 28 Read through a lot of these posts and tried everything. At the end of the day, I bought a $22 mini receiver, ripped out the guts of the subwoofer, wired it through the new receiver, and problem solved. Also, more control over sound. I highly recommend not wasting time with the components in the system. The Klipsch name is about the speakers. Quote Link to comment Share on other sites More sharing options...
