SOURCE: loud humming buzzing sound coming from subwoofer
make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet
SOURCE: My klh subwoofer has R&L
Yes, you use a subwoofer cable and hook it into the mono rca jack in the back of the sub. or you can use a Y splitter 1 female to 2 males. or if your amp has 2 sub outputs (L&R) then use both. I do believe it's said that if you use the high level input, it's better. I forgot why...
Oh yeah. the difference between the 2 is a high level input allows the currant from the amp to pass through the sub, thus allowing the continuation of wattage to your other speakers.
Low level input is only taking a audio signal from the amp. No power is being sen through the connection.

On the subwoofer's L&R input, you'll see a tiny "mono" next to the Left input. Hook up your receiver's single sub output to this jack and you're all set.
SOURCE: Loud hHum from Subwoofer
Sounds like the hum might be mains hum caused by the failure of the power supply capacitor(s) in the sub. It/they will be the largest on the pc board. You will find all the details (needed to replace it) on them. If you find more than one replace both.

Did you ever find a solution for this problem? I have the exact same thing happening with my KLH subwoofer and I'd love to know how to fix it!
