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.

REVIEWS
This is the best version of the 801s in the entire history of the company and, perhaps, one of the best, if not the best high-end loudspeakers on the market today.
Bowers & Wilkins new 801 D4 Loudspeaker is a work of art that also happens to offer world-class sound.
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.
