Loud buzz and hum in my REL subwoofer

Hello,
I recently purchased from this site a REL subwoofer. It work really nice for a few month but lately discovered that it was producing a lound buzz and hum, even when the Receiver is turned off. The only way to stop the buzz and hum is to disconnect the cable from the back of the sub.
has anyone experienced the same problem before? Could it be a cable problem rather than a sub problem ?
Thanks for your help.

I Would try a different cable first.Also if you have some other preamp,or receiver(any thing with a variable output) ,try that too.When the receiver is turned off,most subs power
down.If the interconnect wire broke loose inside from moving things do to cleaning etc.,the sub woofer could recognize stray AC,or RF signals causing the hum and keeping it powered up.
More to discover
