Question about Velodyne CHT-8 Subwoofer
If the hum is from the back of the unit around the amplifier, it may be the transformer. It could be that the mounting is loose.
It could also be that the transformer is going out.
Disconnect all the inputs to the unit, Still hum?
If the hum stops you have something causing noise to the input.
If you have it on a switched circuit, try moving the power plug to a different outlet that is not on a switch. If hum stops, then you have something on that circuit causing the problem
if all inputs are disconnected and it still humms good chance it is the transformer.
