Plz make sure that all your components are on same 110 ac outlet. Ground loop is the most common couse of Humming on sub woofer. try disconnecting one component at a time till hum disappears.

See page E1 regarding placement and safety.
Page 44 - read about "humming".
If you have hum on the sub, is it there with and/or without the input cable attached?
Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.
