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 we 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 our 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. Our 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 we do. We question, we examine, we understand and then we evolve. We use computer modelling to explore and reimagine every aspect of loudspeaker design. Learn more about all the technologies that combine to make 800 Series Diamond so special here.

The state of our art
801 D4 is our flagship and the most powerful model in the new 800 Series Diamond range. Its no-compromise design includes all our most advanced technologies in their purest, most optimised form alongside crossover components of the highest quality. You want our reference loudspeaker? This is it…

"The new B&W Flagships are capable of a sound as informative as it is vivid. They bring to life everything from driving rock to the most subtle of solo instruments and voices, with breath-taking insight into performance and music alike. Yes, they’re demanding of both amplifier and system quality, but get it right and they will thrill and entice like almost no other."

"The sound of the 801 D4 is one of absolute conviction and positivity. Every last shred of information contained in a recording is handed over, in full, with the sort of immediacy that can be literally hair-raising."

"There’s a final point that should be made. For most people, $35,000 is a lot of money for an audio expenditure. In the world of elite loudspeakers, however, that kind of outlay doesn’t get you to the middle of many manufacturers’ product ranges. The Bowers & Wilkins 801 D4s actually represents a terrific value."
