Can You Add a Subwoofer to a Soundbar?

Most soundbars connect with native, manufacturer-paired speakers.  It’s tricky when it comes to connecting a subwoofer to a soundbar.

Generally, soundbars are sold with speakers or they come alone but they don’t include a subwoofer. In fact, many soundbars can only connect with subwoofers that are within their brand lines.

It’s hard to add a standalone subwoofer to most soundbars. It’s typically only possible when the soundbar and subwoofer are sold together and can connect natively to one another.

You may be trying some jerry-rigging ways to connect a standalone subwoofer to a soundbar, but the fact is unless they are natively compatible, it’s not going to be easy.

It’s best to get a soundbar package that includes a subwoofer like this Sony HT-S350.

Steps to Follow When Pairing Subwoofer to a Soundbar

Here, we will look at when both the soundbar and subwoofer pair up automatically and when you have to do it manually.

Connecting an LG Subwoofer to a Soundbar Automatically

Connecting an LG subwoofer to a soundbar that is native is quite straightforward. Provided these steps are met properly. If certain conditions aren’t met, the subwoofer will refuse to pair up with the soundbar

Step 1: Power Up the Soundbar

The soundbar will need a separate power source. Connect the cable into the sucket and the appropriate end into the port labeled DC IN at the back of the soundbar. This is what will power the device.

Step 2: Power Up the Subwoofer

Also to power up the subwoofer, it has to be connected up separately to a power source. Plug the right end of the cable into the DC iN at the back of the subwoofer and the other end into the power source.

Step 3: Power on the Subwoofer and the Soundbar 

Now is time to turn on the subwoofer and the soundbar using the power buttons on each device. If both devices are turned on, you will see a blinking LED light on the subwoofer.

It can take a few minutes for the sub to connect with the soundbar and automatically program themselves.  When the LED light goes green and stops blinking, then the connection is complete.

Connecting the Subwoofer to the LED Manually

Though it would be ideal for the subwoofer to connect automatically, if for some reason it didn’t connect, then you may have to do it manually.

To do so, you will need to follow these steps.

Step 1: Turn the Volume Down

It is important to turn the volume down using the remote control by pressing the button marked “VOL-“.   This is essential to a proper pairing of the sub manually.

Continue pressing the “VOL-”  button. You will soon notice the LED on the back of the soundbar has illuminated. This should be red and after about 2 seconds, the solid light should begin to flash.

Step 2: Find the Remote When the Red LED Indicator is Flashing

Press and hold the “Mute” button on the remote for three seconds. The mute button is mostly presented on the remote as an image of a speaker with an x on it.

Hold that “Mute” button until the LED light indicator is flashing quickly. You notice the difference in the flashing.

Step 3: Find the Pairing Button on the Back of the Subwoofer

You will need something that can allow you to press that button because is a small push button. Maybe a small screwdriver or paperclip will do the trick.

Using the tool, press the pairing button for about 5 seconds on the subwoofer. The LED indicator should be flashing red and green in an alternating pattern.

Step 4: Unplug Both the Subwoofer and Soundbar and Replug Them Back

Unplug both devices from the power sockets for a few moments and replug them back. Moments after doing this, the device should be paired automatically.

If you are wondering how you will know if they are paired, you can tell they are paired by looking at the LED light indicator on the side of the subwoofer. This should turn solid green.

Troubleshooting the Connection

For some reason, your devices might not connect. You can investigate by checking these tips here.

Check to ensure that both devices are as close as possible. This will make it easier for the devices to connect and also improve the sound quality.

Also, check if anything might be obstructing the signal between the sub and the soundbar.

Other devices like microwaves, medical devices, etc can interfere with the connection between the two devices.

Yeah. These are some of the issues that can cause the sub not to pair with the soundbar. After trying the tips above, I believe you will be able to connect the two and you can test by turning the TV on to see if it’s working.

Why Add a Subwoofer to a Soundbar?

On the market, soundbars come in different packages. These include soundbars with external speakers,  those with only built-in speakers ( including some with built-in subwoofers), and those that also include an external subwoofer.

Soundbars come in different sound qualities. Some can perform well without external speakers and others too are very basic.

It all depends on what works for you. But many will argue that subwoofers are crucial for experiencing a soundbar’s full sound experience.

The main reason you will need a sub is to amplify the low-pitched sound coming out from the soundbar.

Many soundbars lack the ability to amplify bass sounds and hence the need for a subwoofer to do that job.

Final Thoughts

LG Soundbars are available on the market for a wide range of sound quality. Depending on your budget, you can get one that will be suitable for you.

After you’ve got your subwoofer, the steps above will help you to pair the subwoofer to the soundbar for better bass sound.

Most of the time, the LG subwoofer and soundbar combination pair easily and without a fuss. If your LG subwoofer does not connect to a soundbar, it might be an easy enough fix.
