    At least that's how I would describe what my Klipsch
    SW-12 does on a regular basis.
    When this annoying hum starts all I need to do is
    jar the floor with my foot or end table with my hand
    and it quits for awhile.It doesn't take much.
    Any ideas as to what's going on?

    Maybe. Sounds like it could be a loose or cold soldered joint in the amplifier portion of your sub. A bad electrolytic capacitor could cause this as well. If you are handy with a screwdriver and soldering iron, you might want to remove the amp and take a peek. I am assuming the unit is out of warranty.
