slight hum from subwoofer

[badrocket]

is it normal to hear a very slight hum from a sub? i can only tell when i'm very close to it, and the system is powered down. it's a logitech z2200 sub, 200w output, quite similar to the one with the z680s.

Offhand it sounds like a ground loop to me. This might be helpful.

"How do I repair my hard drive Zachary?"
"Try Kicking it."

"My dog has cancer Zachary."
"Try kicking it."

"How should I store this priceless Ming vase zachary?"
"Try kicking it."

I have the z-5300's and my subwoofer hums as well and kicking it does not fix it...that was one of the first things I tried.

The logitech support email just repeats what they say in their speaker FAQ and is of no use. I am going to read that ground loop link right now.

it's so slight, i probably won't worry about it, but the ground loop link is a good one. thanks for the info.

I wasn't kidding about kicking it........I did everything except for opening up my HT subwoofer so I just kicked it and it stopped
