Solution
Some low hum may be detected when your speaker system is powered on
without an audio source playing, or when the volume is set at an extremely
low level.
Unplug the power cord from the surge protector (if used), and plug directly
into an AC wall outlet.
Check to make sure all cables are connected properly and are making
a clear connection.
Lower the volume or bass level on your PC, portable audio device, etc.
Increase the volume on the audio source.

Increase bass level on back of subwoofer.
Because the subwoofer is not magnetically shielded, it can cause distortion if
it's too close to your PC monitor or TV set. Move the subwoofer so it's at least
2 feet from the monitor or TV set.
