Volume
When you set up your subwoofer for the first time, you may have to make adjustments
control
several times before you hear what you personally like. Start with the volume at 50%. Adjust
by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without
"boominess."
We recommend that you use your AV receiver to run room correction features (like Audyssey
or Dirac) and allow the receiver to optimize your speakers and subwoofer(s).
