The Bang & Olufsen 3D Sound System for the Audi A4 pushes yet further the reference point for audio performance in the automotive market, creating a highly realistic three-dimensional sound impression. The system comprehensively includes an array of 19 speakers, each housed within grilles that are seamlessly integrated into the interior design of the Audi A4.

The 16 channel Class D amplifier delivers 755 watts of clear, crisp 5.1 surround sound. Together with Fraunhofer Symphoria® technology, the sound system provides an acoustic spaciousness in the Audi A4 that also sets new standards for automotive 3D sound reproduction. Regardless of what is happening outside the cabin, the Vehicle Noise Compensation (VNC) technology incorporated into the amplifier ensures audio consistency is maintained, automatically adjusting timbre and volume based on input from a number of internal and external on-board sensors and microphones.
