Sounds like the amp is faulty. I think the only way you are going to fix this is get Axiom to send you another replacement amp.

Do you have access to a UPS generating its current from a battery? That could isolate completely the sub from your electrical system if that proves to be the problem.
I know a few people in the movie industry who are using that type of solution to fix strange electrical problems on location.

I would not invest in anything at the moment. You should ask for another replacemnt amp that is quality control inspected and tested before it is shipped to you. If another replacment hums, then surely there is somethng more devious going on and time to look at other fixes.

I dunno. Perhaps lug it over to someone else's house or to your workplace and plug it in there. See if it does it elsewhere.

I know a few people in the movie industry who are using that type of solution to fix strange electrical problems on location. Many UPSes use "stepped sine" output, which can also cause transformer hum. It depends on how susceptible the transformer is, and how bad the power is in the house. Sometimes there is so much noise on the 60 Hz sine wave of the house, that a stepped sine from a UPS is actually cleaner.

Hi JohnK, so that means I would have to try yet another AMP? Axiom sent a letter with the replacement saying it had been tested in a enclosure and was working with no problems.

You mentioned you tried different outlets with no success. Have you tried any outlets outside your HT room? Maybe try plugging just the subwoofer into an outlet in your bedroom?

Solar panel? On a serious note, how long is the shipping to Japan?
