5 Series

BMW and Bowers & Wilkins joined forces to create an audio system in the elegant and dynamic 5 Series that delivers an incredibly realistic, immersive audio experience.


6 Series GT

Available as a premium option with the BMW 6 Series Gran Turismo, the Bowers & Wilkins Diamond Surround Sound System redefines what’s possible for audio sound quality.


7 Series

BMW's ultimate luxury sedan, the 7 Series embodies craftsmanship and innovation. The Bowers & Wilkins Diamond Surround Sound System features studio-level technologies such as Diamond Dome tweeters.


The Bowers & Wilkins Diamond Surround Sound System is the first of its kind: an audio system featuring advanced acoustic technologies, including Diamond Dome tweeters, never before seen in a car. From the outset, engineering teams from BMW and Bowers & Wilkins joined forces to create an audio system that works in harmony with the car’s luxurious interior architecture. Their goal was to produce an experience that feels as though you are there with the artist in the studio.



Grown in laboratory conditions, diamond tweeter domes are found in Bowers & Wilkins most advanced studio speakers – and in the BMW 5, 7 and 6 Series GT.


Inspired by the Bowers & Wilkins Nautilus speaker, spiralling diffusion channels soak up reflected sound from the rear of each drive unit, reducing resonance to a minimum.


One of Bowers & Wilkins hallmark innovations, Kevlar helps prevent distortion in the midrange and improves off-axis performance - especially important in cars.

Sound and light

The speakers of the Diamond Surround Sound System include subtle illumination in the front and rear doors and are housed behind etched stainless steel, which allows for complete acoustic transparency.
