B&W 800 D3 (ROSENUT)

The flagship model in the 800 Series Diamond range is more than a speaker. It’s the culmination of half a century of acoustic research and engineering, and the pinnacle of audio performance, offering unmatched levels of clarity and realism.

When John Bowers founded his company in 1966, he dreamed of manufacturing the perfect loudspeaker. We’ve been pursuing his vision ever since, and now, 50 years later, we’ve taken our biggest and boldest leap forward yet in the shape of the 800 D3.





Diamond Dome Tweeters
Incredibly light, yet unbelievably rigid, Diamond is the ultimate tweeter material. Delivering the most revealing, natural treble you will ever hear.

Turbine Head
The Turbine head is the ideal shape for sound dispersion, while its internally ribbed, aluminium construction ensures that it is acoustically inert.

Less resonance, more dispersion

The Turbine Head's massive midrange housing is carefully shaped and inert, ensuring voices and instruments are delivered with extreme purity.

Continuum cone
The Continuum cone delivers pristine midrange performance by effectively negating the break-up behaviour that can adversely effect this all-important part of the spectrum.

Aerofoil cone
The Aerofoil cone’s variable thickness provides added strength where it is needed to maintain its pistonic shape, delivering rock solid bass.
