When it comes to creating the perfect home audio setup, the subwoofer plays a crucial role in delivering deep and impactful bass.

However, many users have reported issues with the subwoofer cutting out unexpectedly. This can be incredibly frustrating, especially if you've invested a significant amount of money in your sound system.

1. Check the Power Connection

The first thing you should do when experiencing issues with your Polk Signa S2 subwoofer cutting out is to check the power connection. Ensure that the power cord is securely plugged into both the subwoofer and the power outlet. Sometimes, a loose connection can cause intermittent power loss, resulting in the subwoofer cutting out.

2. Verify the Audio Source

Another potential cause of the subwoofer cutting out is the audio source. Make sure that the device you're using to play the audio is functioning properly and sending a consistent signal. Try connecting a different device or using a different audio source to see if the issue persists.

3. Adjust the Subwoofer Settings

It's also worth checking the settings on your Polk Signa S2 subwoofer to ensure that they are optimized for your specific setup. Adjust the volume, crossover frequency, and phase settings to find the optimal balance for your audio system. Sometimes, incorrect settings can cause the subwoofer to cut out.

4. Position the Subwoofer Properly

The placement of your subwoofer can have a significant impact on its performance. Make sure that the subwoofer is positioned correctly in your room, away from walls or corners that can interfere with the sound waves. Experiment with different placements to find the sweet spot that delivers the best bass response without cutting out.

5. Check for Interference

Interference from other electronic devices can also cause the Polk Signa S2 subwoofer to cut out. Keep your subwoofer away from sources of potential interference, such as Wi-Fi routers, cordless phones, or microwave ovens. Additionally, try turning off other nearby devices to see if the issue resolves.

6. Update Firmware and Drivers

Software and firmware updates can often address known issues and improve the overall performance of electronic devices. Check the Polk Audio website for any available updates for your specific subwoofer model. Updating the firmware and drivers may resolve the issue of the subwoofer cutting out.

7. Contact Polk Audio Support

If all else fails, it's recommended to reach out to Polk Audio's customer support for further assistance. They may be able to provide you with additional troubleshooting steps or advise whether your subwoofer needs to be repaired or replaced. Polk Audio is known for its excellent customer service, so don't hesitate to contact them for help.

8. Invest in a Power Conditioner

In some cases, electrical fluctuations or power surges can cause the subwoofer to cut out. Investing in a power conditioner can help stabilize the voltage and protect your audio equipment from such issues. A power conditioner acts as a buffer between your devices and the power outlet, ensuring a consistent and clean power supply.

9. Consider a Different Subwoofer

If none of the above solutions work and you're still experiencing issues with your Polk Signa S2 subwoofer cutting out, it might be worth considering a different subwoofer altogether. There are plenty of other high-quality subwoofers available on the market that may better suit your needs and provide a more reliable performance.

10. Upgrade Your Sound System

Investing in a more advanced and reliable setup can ensure a consistent and uninterrupted audio experience. Explore different options and consult with audio experts to find the best solution for your specific needs.


Dealing with a subwoofer that cuts out can be incredibly frustrating, but there are several steps you can take to resolve the issue. By checking the power connection, verifying the audio source, adjusting settings, and positioning the subwoofer properly, you can often troubleshoot and fix the problem. If these solutions don't work, updating firmware, contacting customer support, investing in a power conditioner, or considering a different subwoofer or sound system upgrade may be necessary. Remember, the goal is to create an immersive audio experience, and addressing issues like subwoofer cutting out is an essential part of achieving that.
