    Good Bass, Bad Auto On Feature

    Good bass for home theater. However, the auto on feature is not very good. Does not detect the LFE signals very well. While watching a movie the bass will shut off during the quiet scenes and then turn back on during the action scenes. On and off, off and on, which becomes very annoying so I have to turn off the auto feature during any extended use.
