Klipsch Subwoofer Not Working

Black subwoofer on the floor

Klipsch is a well known brand that makes a range of different audio devices such as speakers and subwoofers. While a home theater speaker set up is a bit difficult to set up and get right at first it’s well worth it. But, here’s what to do if your Klipsch subwoofer is not working at all.

Overall, do a buzz test. Unplug everything except the power cable, and the RCA cable. But, don’t plug the other end of an RCA cable in. Tap the 2 ends of the RCA cable together, and see if you hear a buzz, if not do the steps below.

If it does buzz then there is an issue with the audio input. Such as the signal from your receiver, so this is where you should identify an issue. Your Klipsch subwoofer can also be getting no power at all. Below, I will cover in step by step detail each of the troubleshooting steps to fix a Klipsch subwoofer that is not working.

Klipsch Subwoofer Not Working

A Klipsch subwoofer can be a stand alone speaker, or are available as a subwoofer and soundbar combination. In either case, the subwoofer can stop working, or not work out of the box. Here are detailed instructions for what to do if your Klipsch subwoofer is not working.

As a general rule, there is an issue with either the power to your Klipsch subwoofer or the audio input. Both need to be checked. Start by making sure your subwoofer is getting power but checking the power switch at the back is in the ‘on’ position. Then do the steps below.

When the power switch is in the on position the LED light on your Klipsch subwoofer will be lit up. If it’s not lit up, there is an issue with your subwoofer getting power. This can be because:

  • The power cable is faulty
  • The power cable is not plugged in all the way
  • The wall outlet isn’t supplying power
  • There is an issue with one of the components on your subwoofer

On the audio side the issues are:

  • The audio cables aren’t plugged in all the way
  • The audio cables are plugged in incorrectly
  • The volume is set too low on the subwoofer, or receiver

If your subwoofer is not getting power then unplug it from the wall. Then check that the power cable at the back of your subwoofer is pushed in all the way. When it’s not plugged in all the way, it won’t supply enough power.

Plug something else into the same wall outlet that you’re trying to use for your subwoofer. The easiest is typically a smartphone charger plugged into a phone or tablet. When the wall outlet isn’t supplying power the issue is with the circuit breaker for your house.

If your subwoofer powers on – the LED light, lights up – then it’s an audio issue. Refer to your owners manual and check that the cables have been installed correctly. If a small mistake was made, it can stop the audio signal from getting to the subwoofer.

Then check the volume on the subwoofer is turned up at least half way. And try turning up the master volume, and bass volume on your receiver.

Klipsch Subwoofer Not Connecting/Pairing

A Klipsch subwoofer will automatically connect and pair to other Klipsch devices like a soundbar provided they are both turned on and within 30 feet (10 meters) of each other. In some cases, it won’t pair automatically, or it will not pair after doing the manual pairing steps. Here’s what to do if you have this issue.

In general, do a soft reset of both devices. This involved turning them off, disconnecting them from the power. Wait for about 30 seconds, then plug them back into the power and both devices on again. If they still aren’t pairing, do the steps below.

The device you’re pairing your Klipsch subwoofer to needs to be in pairing mode. If you’re unsure whether it’s in pairing mode, then refer to the owners manual for the device you’re trying to pair your subwoofer to. A Klipsch subwoofer will automatically go into pairing mode when it first turns on.

You can tell it’s pairing because the light will flash. Sometimes, there can be a bit of a glitch, and you need to manually put it into pairing mode. This is done by holding down the small button that’s located where the power cable plugs into the back of your subwoofer.

You hold it down for 3 seconds to put it into pairing mode. You will know you’ve put it into pairing mode successfully because the LED light will flash. If it’s still not pairing then get in touch with Klipsch support because there’s most likely an issue with your subwoofer.

Klipsch Subwoofer Not Making Sound

Once a subwoofer has been set up correctly, it will play perfectly fine non-stop. It can be a bit complicated to get it working because there are a few wires, and a few different places where the settings can be adjusted. However, if no sound at all is coming from your Klipsch subwoofer this is what you should do.

Overall, it is not receiving an audio signal. This is typically because it’s not connected correctly to the receiver or audio device. First, identify that your Klipsch subwoofer is getting power by making sure it’s turned on, and the LED light is lit up. Then, do the following steps.

There are 5 issues that can cause a Klipsch subwoofer to not produce sound. They are:

  • The subwoofer volume is set too low and needs to be turned up.
  • The bass volume on the receiver is set too low and needs to be turned up.
  • The master volume on the audio device such as the receiver is set too low and needs to be turned up.
  • The cables aren’t connected correctly
  • One or more of the cables are faulty

A good first step to isolate if the issue is with the way the subwoofer has been connected is to plug in a smartphone to the RCA cable that goes into your subwoofer. This does require an AUX cable, which you may or may not have. If not then check what the volume is on your subwoofer.

The volume knob for your subwoofer is at the back of the subwoofer. Provided the volume on your subwoofer is about half of the maximum, it will produce sound. Next check the master volume, and bass volume on your receiver.

Next, refer to the owners manual for your subwoofer, and double check the cables are installed in the right places. After that, if you have spares of the cables that connect your subwoofer to your audio device, swap them out. This will identify if the issue is with the cables.

There are a range of settings for the receiver and subwoofer that you should check over, explained in this article on the official Klipsch website. Finally, if none of these steps worked then contact Klipsch support.

If the other device you’ve plugged into the same wall outlet isn’t working, then there’s an issue with the wall outlet. Typically, this occurs because a fuse on the circuit breaker has blown or has clicked into the off position. But, the power cord can also have come loose. Unplug the power cord from the wall outlet.

Then disconnect it from the back of your subwoofer, and plug it again. Making sure you push it in all the way.

A Klipsch subwoofer, like most subwoofers, has a fuse that stops it from getting damaged when there is a power surge. This fuse can blow, and can be replaced with a new one.

Klipsch Subwoofer Keeps Turning Off

Once you turn a Klipsch subwoofer on, it will stay on all the time, and you can tell it’s on because the LED light will be lit up. There are a few reasons why a Klipsch subwoofer can keep turning itself off. Here’s what they are, and how to stop it from happening.

Overall, your Klipsch subwoofer is in standby mode and this is part of normal operation. Otherwise the wall outlet may not be sending enough power, an internal component is faulty, or the power cable or audio cable are faulty. Refer to the steps below to identify what the issue is.

Inspect the switch at the back of your Klipsch subwoofer to see whether it’s set to on, or auto. When it’s set to auto it will go into standby mode when it’s not playing anything. The area of your home may have a wiring issue.

Or, there may be too many devices plugged into the same area. For example, you have a multi port power adapter with a lot of different devices plugged into it. However, if you only have 2 to 3 devices plugged in, then this likely isn’t the issue.

Plug your subwoofer in at a different part of the house that doesn’t have as many devices plugged in, or unplug some of the devices and see if it still keeps turning off. Also, when the power cable is faulty, the power supply can go in and out, which can cause your subwoofer to turn off.

Subwoofers have unique power cords, so you will need to buy a new power cord. Before doing so, get in touch with Klipsch support, as there may be an internal issue with your subwoofer, which they can help you troubleshoot over live chat or over the phone.

Klipsch Subwoofer Blinking Light

There is an LED light on Klipsch subwoofers that indicates whether it’s getting power, and whether it’s set to ‘on’ or ‘standby’ mode. In some cases the LED light will blink. This is why this happens, and what it means.

As a general rule, it means it’s in pairing mode and trying to pair to another device but it can’t. A Klipsch subwoofer is put into pairing mode by holding down the button above where the power cord connects to the subwoofer, or if it’s turned on and off again.

But, if the flashing light does not go away after about 1 minute then you should contact Klipsch support. Klipsch recommends contacting them if this issue occurs with your Klipsch subwoofer. If some of your other devices can connect wireless and you want to, such as a Klipsch soundbar, then you need to put the soundbar or other device you want to pair to your Klipsch subwoofer in pairing mode.

How to Reset Klipsch Subwoofer

There can be issues with Klipsch subwoofers, and like other electronic devices doing a reset can fix it. Here’s instructions for how to do both a soft reset and a hard (factory reset) on a Klipsch subwoofer.

As a general rule, press and hold the power button and source button for 10 seconds to factory reset a Klipsch subwoofer and soundbar combo. This needs to be done on the subwoofer itself, not using the remote. Some Klipsch subwoofers can not be factory reset.

A soft reset works for any Klipsch subwoofer. To do a soft reset turn it off, then disconnect it from the wall outlet, plug it back in, and turn it back on. It does vary based on model, so refer to the owners manual for your specific subwoofer model to see if it’s possible and how to do it.

In general, first verify that your subwoofer is getting power by seeing if the LED light is lit up, when it’s turned on. If it’s set to ‘on’ but the LED light is not on then it means your Klipsch subwoofer is not getting power. Additional troubleshooting steps are explained below.
