The Reference 400CF allows you to select the output level of your O+ subwoofer. All our EQ options offer Deep bass reproduction without the loss of your music's clarity. We will never add bass at the cost of accurate sound reproduction.

  • Balanced: Detailed bass reproduction.
  • Full: Rich bass sound. The Full EQ helps compensate for the canceling drone of an Aftermarket exhaust.
  • Robust: Max impact sound. Bass that is felt without the loss of clarity.
