Troubleshooting
Subwoofer not producing sound
Ensure the subwoofer is powered on and wirelessly paired with your TV or soundbar. Check the BRAVIA Connect app or your TV/soundbar settings to confirm the subwoofer is enabled and volume levels are appropriate. Verify that the connected device is outputting low-frequency audio.
Humming or buzzing noise
This can indicate vibrations. Ensure the subwoofer is on a stable surface. Check that the dual opposing drivers are functioning correctly and not obstructed. Ensure all cable connections (if any are used) are secure and not causing interference.
Intermittent sound or dropouts
If using wireless connection, ensure there are no major obstructions between the subwoofer and the source device. Minimize potential wireless interference from other devices. Try moving the subwoofer closer to the source device.
Bass sounds muddy or distorted
Adjust the subwoofer's placement in the room, as acoustics can significantly affect bass quality. Lower the subwoofer volume slightly. Ensure the connected audio source is providing a clean bass signal.

Setup, Compatibility & Care
Setup: The BRAVIA Theatre Sub 9 is designed for straightforward setup. For compatible BRAVIA TVs and soundbars, wireless pairing can be initiated through the TV or soundbar's settings menu. The BRAVIA Connect app, available for smartphones, provides detailed step-by-step instructions and can guide you through the wireless pairing process. Ensure the subwoofer is placed in its intended orientation (front or side-facing) and connected to a power outlet.
Compatibility: This wireless subwoofer is optimized for use with Sony BRAVIA TVs and soundbars. While it can be used with other home theatre systems that support wireless subwoofer connectivity or via a wired connection (if applicable via a connected soundbar/AV receiver), seamless integration and advanced features like dual subwoofer playback are best achieved within the Sony ecosystem.
Care: Keep the subwoofer clean by wiping the exterior with a soft, dry or slightly damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish. Ensure the ventilation ports are kept clear of dust and obstructions to maintain optimal performance and prevent overheating. Do not place objects on top of the subwoofer.
