I have a Cerwin Vega sub that hums all the time. I found you site tonight and tried a few things. The noise comes from my cable TV. I went outside and cleaned the ground cable. Nothing happened. I went and bought 2 70-300 transformers and nothing happened.
When the cable is hooked up the sub will not go onto standby.
Anyboby have other suggestions
Regards,

Have you tried plugging your subwoofer into a different outlet, preferably on a separate circuit?

If the noise is coming from the Cable TV, try an isolation transformer. Check out the Calrad 75-504

Try Marvac Electronics if you're in Southern California. About $8.00.

If the sub has a three-prong plug, you could try one of those two-prong "cheater" adaptors. That worked for my Hsu.

Hi g_hunt,
See my answer to "Speaker Hum" (Curtis and Kevin). If you are on Rogers' cable system in Toronto, you have to keep complaining until the guy comes and installs an earth ground--if nothing else works.
