What should I do if the subwoofer is not powering on?

Avoid exposing the subwoofer to extreme temperatures or moisture. If not in use for extended periods, unplug it from the power source.

Is it possible to repair the subwoofer myself if it stops working?

While some basic troubleshooting can be attempted, such as checking connections and replacing fuses, internal repairs should be conducted by qualified technicians to avoid further damage or voiding the warranty. Consult Sony support or a professional for repairs.

What crossover frequency should I set for the Sony SA-W70ES?

How can I tell if the subwoofer is producing sound correctly?

Play a bass-heavy audio track and listen for clean and deep bass without distortion. You can also perform a subwoofer test tone if available on your AV receiver. Walk around the room to ensure even bass distribution. If the sound seems off, check the volume, connections, and settings.
