In this article, you will learn how to connect a subwoofer to a soundbar. We will provide step-by-step instructions to help you easily set up your subwoofer and enhance your sound experience. Whether you have a Bose, Sonos, Samsung, Yamaha, Sony, JBL, LG, Vizio, Polk Audio, or Klipsch soundbar, we’ve got you covered. Stay tuned to discover the simple and effective ways to connect your subwoofer to your soundbar.


When it comes to enhancing your audio experience at home, connecting a subwoofer to your soundbar can make a significant difference. A subwoofer is a specialized speaker designed to reproduce low-frequency sounds, commonly known as bass. On the other hand, a soundbar is a slim, compact sound system that can improve the audio quality of your TV or other devices. By combining these two devices, you can achieve a more immersive and powerful sound. In this article, we will guide you through the process of connecting a subwoofer to a soundbar, discussing compatibility, connection methods, placement, troubleshooting, and more.


Before getting into the details of how to connect a subwoofer to a soundbar, it is crucial to ensure that your subwoofer is compatible with your soundbar model. Different brands and models may have specific compatibility requirements. Therefore, it is essential to check your soundbar’s user manual or contact the manufacturer’s customer support to confirm whether your subwoofer can be connected to your soundbar.

Furthermore, it is vital to determine whether your soundbar has a dedicated subwoofer output. This output allows for a seamless connection between your soundbar and subwoofer, optimizing the audio performance. If your soundbar does not have a dedicated subwoofer output, there are still options available, which we will discuss later in this article.

Connection Methods

When connecting a subwoofer to a soundbar, you have two primary options: wired connection and wireless connection. The choice between these methods primarily depends on the capabilities of your soundbar and subwoofer.

Wired Connection

  1. Locate the subwoofer output on the soundbar: To establish a wired connection, you need to find the subwoofer output on your soundbar. This output is often marked as “Subwoofer,” “Sub Out,” or “LFE Out.”

  2. Connect the subwoofer to the soundbar using an audio cable: Once you have located the subwoofer output, connect one end of an audio cable to this output and the other end to the input on your subwoofer. Ensure that the connectors are securely plugged in.

  3. Adjust the subwoofer settings on the soundbar: After connecting the subwoofer, you might need to adjust the settings on your soundbar to optimize the bass output. Many soundbars provide options to control the volume and crossover frequency of the subwoofer. Experiment with these settings to achieve the desired audio balance.

Wireless Connection

  1. Check if your soundbar and subwoofer support wireless connection: Wireless connectivity between a soundbar and subwoofer typically relies on technologies such as Bluetooth or Wi-Fi. Verify whether both devices support wireless connection and have the necessary capabilities.

  2. Pair the soundbar and subwoofer via Bluetooth or Wi-Fi: If your soundbar and subwoofer support wireless connectivity, consult the user manuals for instructions on how to pair them together. The process usually involves putting both devices into pairing mode and selecting the appropriate connection settings on your soundbar.

  3. Adjust the wireless subwoofer settings on the soundbar: Once the wireless connection is established, you may need to adjust the settings on your soundbar to optimize the performance of the wireless subwoofer. Similar to the wired connection method, these settings often include volume control and crossover frequency adjustments.


Proper placement of your subwoofer is crucial to achieve optimal sound quality. Here are some essential tips to consider:

  1. Position the subwoofer for optimal sound: Place the subwoofer near the soundbar, ideally on the same side or within a reasonable distance. This proximity ensures that the sound from the soundbar and subwoofer is synchronized, providing a cohesive audio experience.

  2. Avoid blocking the subwoofer’s port or driver: The port and driver of a subwoofer are responsible for producing the powerful bass. Make sure no objects or furniture obstruct these components, as it can negatively impact the sound quality. Additionally, avoid placing the subwoofer in a corner, as this can create an excessive “boomy” bass effect.

Testing and Troubleshooting

After connecting your subwoofer to the soundbar, it is crucial to test its functionality to ensure everything is working correctly. Here are some steps you can take:

  1. Test the subwoofer’s functionality: Play audio content that contains low-frequency sounds or bass-heavy music to assess the subwoofer’s performance. If you can hear the deep bass clearly and feel its impact, it indicates that the subwoofer is functioning properly.

  2. Troubleshoot common connectivity issues: If you encounter any issues with the subwoofer’s connectivity or sound quality, there are a few troubleshooting steps you can try. First, check all cable connections to ensure they are secure. If you are using a wireless connection, make sure both devices are within the recommended range and not experiencing interference from other devices. Additionally, consult the user manuals or contact customer support for specific troubleshooting guidance.

Soundbar Settings

To optimize the bass output and overall audio performance of your soundbar, adjusting specific audio settings can make a noticeable difference. These settings may vary depending on the soundbar model but typically include:

  1. Bass control: Most soundbars provide the option to adjust the bass level. Experiment with different settings to determine the right balance for your listening preferences and the content you are enjoying.

  2. Equalizer settings: Some soundbars offer equalizer presets or manual adjustments, allowing you to fine-tune the audio output according to different genres or personal preferences. Try different equalizer settings to find the one that enhances the overall listening experience.

External Subwoofer Options

If your soundbar does not have a dedicated subwoofer output, there are still options available to connect an external subwoofer. These options include using HDMI ARC (Audio Return Channel) or utilizing a separate amplifier or receiver with subwoofer outputs. Consult your soundbar’s user manual or contact customer support to explore these alternative connection methods and ensure compatibility.


Connecting a subwoofer to a soundbar can significantly enhance your audio experience by reproducing deep and impactful bass. By following the steps outlined in this article, you can ensure a seamless and optimal connection. Remember to check the compatibility between your soundbar and subwoofer, choose the appropriate connection method (wired or wireless), and position the subwoofer correctly for the best sound quality. Additionally, make use of the available soundbar settings to fine-tune the bass and overall audio output. With a properly connected subwoofer, you can enjoy a more immersive and satisfying listening experience.
