BMW 7 Series

The Bowers & Wilkins Diamond Surround Sound System has been designed exclusively for the BMW 7 Series. This sound system is the first of its kind, featuring studio-level acoustic technologies never before seen in a commercial car including Diamond Dome tweeters. The result is a truly revelatory audio experience – and a giant leap forward for in-car sound.

Diamond dome tweeters

The properties of diamond are prized in highly specialised industrial applications, from neurosurgery to CERN’s Large Hadron Collider. Its unique stiffness-to-lightness ratio also makes diamond the perfect tweeter material. Developed for our flagship 800 Series Diamond speakers, diamond tweeter domes are capable of frequencies far beyond the range of human hearing, resulting in superb clarity and detail.

Advanced materials


The Diamond Surround Sound System also utilises advanced materials for midrange and bass drivers in the form of Kevlar and Rohacell. This combination provides clear vocals, and rock solid bass no matter where the listener is sat in the car.

Nautilus


The tweeters in the BMW 7 Series also benefit from Nautilus spiral diffusers, a technology derived from Bowers & Wilkins iconic Nautilus loudspeaker. This innovative technology ensures that unwanted sound never reaches the ears of the listener.

Perfectly integrated

The Diamond Surround Sound System is perfectly integrated into the cabin of the new BMW 7 Series – acoustically
and aesthetically. Tuned by the people responsible for the 800 Series Diamond, it utilises stainless steel speaker grilles, which have audio-ideal Fibonacci patterned holes that allow more sound to pass through and blend into the luxurious interior. Subtle illumination on the Mirror-sail tweeters is designed to highlight the Diamond tweeter and the
Nautilus spiral technology.
