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

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 their newest technologies and most original thinking. Small wonder it has become an icon.

The all-aluminium Turbine Head houses B&W's 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.

Sometimes, making a big difference takes unconventional thinking. B&W’s new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and colouration that a traditional fabric spider can generate. The result? Midrange transparency you wouldn’t believe.

Bowers & Wilkins use advanced computer modelling and material analysis to refine every structural and acoustic element. Each innovation serves a measurable purpose, ensuring the 801 D4 reflects a continual evolution of loudspeaker design rather than aesthetic change alone.
