Bass tones aren't loud enough. How can I make them louder?

• Try the following:
  • Use the Bass setting to increase the bass. See Adjusting the Sound.
  • Use the Test Tones function to increase the output of the subwoofer. See Using Test Tones to Adjust the Sound.
  • If you rearranged your room or moved your subwoofer to a different location, try switching the PHASE control on the back of the subwoofer.
