This can be caused due to an increase in local interference. The hum is decreased when you plug in the satellites because the interference is spread over a longer area.\015\012\015\012You may notice that speakers tend to hum around things like cell phones and power outlets. To see if this is the case, move the speakers to another part of the room if you can, slide the desk around, plug the computer in at another room, something like this. If the hum gets louder or quieter, it is interference at your new place. This can be solved by finding a new area to set up your computer stuff at. Since it's mostly the subwoofer, try elevating it off the ground, there may be a power main running under the floor.
The hum problem can be fixed in two ways.

First\015\012unscrew the 18 screws and fold out the heat-sink back-panel. Look\015\012inside towards the right and you see the ring-transformer.

Using\015\012a 14mm wrench-key you can either(1) tightened the loose bolt or(2)\015\012completely remove the transformer and with tie-wraps fix it to the rear\015\012side of the wooden triangle. Put some foam-plastic cushion around the\015\012transformer, isolating its vibrations from the box.

I now have one pretty silent(1) and one completely silent(2) bass units.
