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 Bowers & Wilkins 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 Bowers & Wilkins’ best yet, upgraded with extensive aluminium bracing to reinforce key stress points.


Turbine™ Head
The all-aluminium Turbine Head houses our 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 midrange sound yet.
Biomimetic Suspension
Sometimes, making a big difference takes unconventional thinking. Bowers & Wilkins’ 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 science of sound
Innovation is at the heart of everything Bowers & Wilkins do. They question, they examine, they understand and then they evolve. Bowers & Wilkins use computer modelling to explore and reimagine every aspect of loudspeaker design.
The State of our Art
801 D4 is Bowers & Wilkins’ 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. You want their reference loudspeaker? This is it…
