Getting more bass:

  1. Placing the subwoofer against a wall or in a corner can help increase bass substantially.  Always move your sub if you are disappointed with the sound.
  2. Adding more subs can give you a 6db increase in output PROVIDING you place the subs next to each other.
  3. Arranging your subs effectively and adding delay to subs can result in less sound going towards the stage area.  This is called a cardoid sub system.
