800 Series Diamond™
An icon reborn
This is not just another speaker range.
Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins.
This is their benchmark, their icon; the most advanced range of loudspeakers they know how to make.
For them, the 800 Series Diamond is everything they know, and everything they are.
Decades in the making
John Bowers wanted the original Model 801 to clearly be superior to anything he had done before: to be the best loudspeaker the world had ever heard.
Over the decades that have followed, they have constantly evolved his original design, but his passion for perfection continues to inspire them to this day.
A legacy like no other
Other speakers merely replay recorded music.
800 Series Diamond makes it.
The speaker of choice for recording industry professionals for decades, it has helped artists and studios the world over to create the music and film soundtracks that have shaped a generation.
The science of sound
Innovation is at the heart of everything they do.
They question, they examine, they understand and then they evolve.
They use computer modelling to explore and re-imagine every aspect of loudspeaker design.

Form meets function
Their design always has a purpose.
Decades of cutting-edge research into loudspeaker design have given us a deep understanding of how to make them sound wonderful.
And if that same knowledge also inspires beautiful forms wrapped in a range of four luxurious finishes, who’s complaining?
The loudspeaker that sets the standard other high-end designs will be judged by for years to come.
Endowed with every new technology the 800 Series Diamond™ has to offer, the reference-quality 801 D4 is an instant icon
40 years of excellence
Innovation. 801 D4 is defined by it.
In each of its incarnations over the decades, 801 has always been the most advanced loudspeaker that they know to make at that particular point in time, a showcase of all our newest technologies and most original thinking. Small wonder it has become an icon
The ultimate Matrix™
Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage.
The Matrix assembly in 801 D4 is their best yet, upgraded with extensive aluminium bracing to reinforce key stress points.
The all-aluminium Turbine Head houses their Continuum™ midrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances.
At the same time, it’s decoupled from both the bass enclosure and the tweeter body.
The result? The most realistic mid-range sound yet.
Sometimes, making a big difference takes unconventional thinking.
Their new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and coloration that a traditional fabric spider can generate.
The result? Midrange transparency you wouldn’t believe.
The state of their art
801 D4 is their flagship and the most powerful model in the new 800 Series Diamond range.
Its no-compromise design includes all their most advanced technologies in their purest, most optimised form alongside crossover components of the highest quality.
