Created by Bowers & Wilkins for BMW.

True Sound Matters.
Music has been a part of the driving experience for decades. It’s not to what, but how we listen that makes all the difference. And that’s what we call True Sound; the reproduction of the intricate details that were captured when the recording was made. Lost by many, exquisitely reproduced by a rare few:  Together with BMW, the Bowers & Wilkins Diamond Surround Sound System is designed to deliver an in-car sound experience that has unparalleled accuracy and authenticity. For high-fidelity audio that’s all around you. Filling your BMW with music as the artist intended it, making your drive even more connected to who you are. That’s True Sound.

A fusion of excellence in sound, form, and function.

Sound engineering, cutting edge technology, design and aesthetic come together to turn a routine drive into an unforgettable experience.

Powerful sound you can feel.

So real, you wish the journey would never end.

Sound power might be measured in watts. But for a driver it’s measured in emotional intensity. With the Bowers & Wilkins Diamond Surround Sound System—expect a reproduction so close to the original — you feel it everywhere. Sound quality that brings you this close to the artists you love isn’t produced effortlessly. It takes up to 20 high-performance Bowers & Wilkins loudspeakers with 1500 watts to power this feeling.

Cutting-edge technology for the most accurate sound reproduction.

Revealing layers of music for complete immersion.

Just as with any band or orchestra, so with our technology — the whole is greater than the sum of the parts. A crisp and more detailed treble performance. Sound clarity free from distortion. The perfect timbre to reproduce the human voice. Bass performance that’s tight and punchy. From the advanced materials like Diamond, Aramid Fibre and Rohacell® to a custom-designed array of tweeters, subwoofers and diffusion channels, expect the best sound you can listen to in a BMW.

Beautiful design you can hear and see.

Enjoy a symphony of sound and design.

Exquisite design. Luxurious details. And impeccable engineering: There’s no denying the Diamond Surround Sound System from Bowers & Wilkins looks just as good as it sounds. From stainless-steel speaker grills that feature uniquely designed and acoustically optimised Fibonacci patterned holes, to illumination effects in the front and rear doors. It all perfectly blends in to the interior design of the car.

Personalised sound that’s right for you.

Listen better to feel better.

Mood and music are inextricably linked. That’s why the Diamond Surround Sound System from Bowers & Wilkins lets you choose from five carefully crafted presets to experience a new way of listening to your music.  Carefully tuned to make you feel as if you were at a studio, at a live concert, on the stage itself or focussed on rear-seat passengers with Lounge Mode.

Abbey Road Studios is synonymous with the landmark recordings and legendary artists that have defined modern music. Since 1980, our engineers have used Bowers & Wilkins sound equipment to produce and master some of the best music of all time. So often, the music that will soon be heard everywhere, is first heard at Abbey Road through Bowers & Wilkins speakers.

The Diamond Surround Sound System is the first-of-its-kind car sound system with Diamond-Dome tweeters – a brilliant sound experience! Our work with Bowers & Wilkins starts as early as the car design itself. The development and integration of the speakers as well as the tunings of the audio systems are done together with Bowers & Wilkins to get the best acoustical performance for the customer.

– Thomas Würdinger, Team Lead Toolbox Audio, Audio Systems & Equalizing, BMW Group

The same world-class acoustic engineers that develop our highly acclaimed loudspeakers also tune and perfect our in-car systems to ensure that we deliver an experience we are truly proud of, and that can be held in the same regard as the speakers we manufacture. Only through this consistency of approach can we deliver True Sound for BMW.

– Dan Shepherd, Director of Automotive Partnerships, Bowers & Wilkins

Engineering excellence is shared DNA.

Sound is an essential element of your BMW driving experience. It’s an extra layer of sensation that makes the journey as defining as your arrival. No wonder then, that BMW joined forces with Bowers & Wilkins to deliver the most advanced in-car audio system ever. Designed exclusively for BMW, the Bowers & Wilkins Diamond Surround Sound System is developed with one goal in mind: To offer highest audio quality and the most accurate reproduction of the original recording. A fusion of excellence in sound, form, and function, it blends seamlessly into your beautifully crafted BMW interior.

50 years+ Heritage in Audio Excellence.

It’s more than 50 years ago that John Bowers set up a company dedicated to the pursuit of True Sound: sound reproduction completely faithful to the original recording in every way. Since its origins in 1966, Bowers & Wilkins has gone on to create some of the world’s most revered loudspeakers and, in turn, earning the trust of some of the most demanding international recording studios, including London’s Abbey Road Studios. As John Bowers often said, “The best loudspeaker isn’t the one that gives the most. It’s the one that loses the least.” Now, True Sound is available in your BMW — offering a cleaner, accurate and authentic sound that makes audio perfection a realistic benchmark.
