A subwoofer may come paired with the soundbar you purchased, or you may add one by making s separate purchase. Either way, they possess the same function.

These are relatively small square or rectangular devices that are loaded with numerous audio speakers or drivers including ones that are called woofers and tweeters.

The tweeters are responsible for producing high-frequency audio while woofers are for low-frequency sounds. These speakers all packed into one device are what subwoofers are, most of them being wireless, making your entertainment all the more enhanced and immersive.

Why Add Subwoofer To Soundbar

As we just described above, all those speakers within the subwoofer work together to produce the most detailed and booming audio with rich bass which the soundbar alone cannot produce.

These devices are super-compact, barely taking up any room, blending in with the soundbar and your room without looking out of place. You get the richest sound performance without missing a single low note.

If you’re a music or fan of movies, you’d know the difference as even the lowest notes of audio make all the difference in the world.

In comparison to their enhanced audio performance, these devices are compact and sleek-looking. Hence, placing them in your living room doesn’t disrupt the aesthetic balance.  You also get to place them flexibly in the room as their sound isn’t localized.

Connecting them to your soundbar is simple, and since they are a very affordable piece of tech for any budget, there is absolutely no reason for not getting one!

How To Connect Subwoofer To Soundbar

Wireless Subwoofer

Connecting your subwoofer wirelessly to your soundbar is one of the most convenient methods. Most models’ included wireless subwoofer automatically pairs up with your soundbar when it is turned on. If not, you can connect it manually.

The procedure for connecting them wirelessly differs slightly from brand to brand, but the basics are as follows.

  • Turn off your soundbar.
  • Plug in the power cables of both the soundbar and the subwoofer to a power outlet.
  • Using something pointy, such as a small paper clip, insert it inside the hole labeled ID SET and press the button inside for around 5 seconds.
  • Some models have a regular ID SET button that you can press directly with your finger. Do the same thing by pressing and holding down on it.
  • As you keep holding it, you’ll notice that the indicator for Standby shuts off and another indicator light starts to flicker. This is the Link indicator.
  • On the soundbar’s remote control, press the Mute button and hold it.
  • If the Menu button doesn’t work, try pressing & holding the UP or the Volume Increase button instead.
  • Keep holding until you the phrase ID SET appearing on the soundbar.
  • Turn your subwoofer on as the indicator on the subwoofer keeps flickering/blinking.
  • Once the subwoofer is connected, the indicator light will stop blinking and remain solid.
  • Start from the beginning if the light keeps blinking still as it means the subwoofer could not connect.

Wired Subwoofer

It is not possible in general to connect a subwoofer to your soundbar with cables. This is because they are designed in a way for being standalone devices. Also, most models are only compatible with their native brands.

It is hence ideal to purchase soundbars that come with subwoofers included for convenient connectivity. But for extreme situations, you can, of course, adopt a makeshift method to get the job done.

This method, I tell you, is not traditional at all, and you’d be sacrificing the sound quality to some extent. You can follow these steps to connect those subwoofer models that don’t directly allow wired connection to your soundbar.

  • Along with your subwoofer and soundbar, procure a stereo mini mixer and a receiver.
  • Next, you go to the stereo mixer from the front left, center, and, front rightchannel pre-outs.
  • You then connect your soundbar to the receiver, and your desired subwoofer to the receiver as well.

All these connections will end up compromising your audio output from the subwoofer, not to mention the hassle this method involves. Not everyone will have these tools at hand, neither is this an easy procedure for tech-amateurs.

Hence, it’s best to purchase a soundbar-subwoofer combo for the most convenient connection and phenomenal performance.

An example of a model that supports wired connectivity to a soundbar is the Yamaha Subwoofer-(NS-SW050BL). It will be ideal to stick to such a model as connecting them to your soundbar is simple and straightforward.

  • Given that your soundbar has an appropriate input interface for the subwoofer, you’d need a monaural (mono) sound cable.
  • Ensure that the cable possesses thecorrect connectors on both ends.
  • At the back of your soundbar, find the Subwoofer Out interface
  • Find the input interface on your subwoofer.
  • Plug the ends of the cable into these corresponding ports and we’re done.


In order to enjoy the most premium bass and riches sound quality, it is essential that you know how to connect subwoofer to soundbar perfectly.

While wireless models are easiest to connect, not all are capable of wired connections to your soundbar. Hence, it’s best to stick to the wireless ones for maximum flexibility and convenience.

But if you do choose to go for a wired model, ensure that it supports wired connectivity as makeshift methods may not be everyone’s cup of tea.

Either way, now that you know the importance of subwoofers and their methods of connection, get set up Asap and let’s get ready to rumble!
