A4 Limousine | Avant

Bang & Olufsen 3D Sound System

The Bang & Olufsen 3D Sound System for the Audi A4 Limousine and Audi A4 Avant 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.


The Bang & Olufsen Dynamic Lines Design feature brings together excellent styling with unrivalled acoustic transparency. Speaker grilles follow the design line of the interior and include anodized aluminum details and logos, LED lighting and visibility from the interior and exterior of the vehicle.

The system also ensures that the respect for individual preferences is never forgotten: An array of settings allows passengers to adjust volume levels in their areas.
