STRUER/KARLSBAD - Audi has just released the new and improved Audi A4 to an eagerly awaiting luxury sedan market. Supporting the high performance nature of the Audi brand, the new Audi A4 Saloon and Audi A4 Avant include an optional Bang & Olufsen 3D Sound System that offers an unparalleled level of acoustic transparency and sets the benchmark of excellence in the automotive audio systems market.

“The Bang & Olufsen 3D Sound System in the Audi A4 brings fascinating 3D sound to all who hear it, adding an exciting new dimension to the listening experience,” said Jens Peter Zinck, Head of Bang & Olufsen Automotive for HARMAN.


For the ears

The Bang & Olufsen 3D Sound System for the Audi A4 pushes yet further the reference point for audio performance in the automotive market. 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 Bang & Olufsen Dynamic Lines Design feature brings together excellent styling with unrivalled acoustic transparency. 

The 16 channel Class D amplifier delivers 755 watts of clear, crisp 5.1 surround sound. 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. Using Fraunhofer's Symphoria® technology, the sound system provides an acoustic spaciousness in the Audi A4 that sets new standards for automotive 3D sound reproduction.


For the eyes

The elegant shape and design of the exterior of the Audi A4 weaves itself into the vehicle’s interior. The combination of the cabin’s spaciousness, luxury and subtle attention to detail provides a perfect stage for Bang & Olufsen Automotive engineers to display a new visual design that will carry into future partnerships with Audi.

These attributes further integrate the audio system into the overall interior design of the Audi A4, ensuring that Bang & Olufsen maintains a strong and distinct brand identity. Speaker grilles with a specific Dynamic Lines Design follow the design line of the interior and include anodized aluminium details and logos, LED lighting and visibility from the interior and exterior of the vehicle.


For the heart

By design, the Bang & Olufsen 3D Sound System for the Audi A4 aims to please both driver and passenger. It is capable of flawlessly reproducing a multitude of music categories, with a focus on being unblemished and distinctive, effectively and virtually transporting listeners to packed stadiums, recording studios, jazz clubs or concert halls on their drive. 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.
