The Bowers & Wilkins 801 D4 is a loudspeaker that sets the standard other high-end designs will be judged by for years to come. Endowed with every new technology the 800 Series Diamond has to offer, the reference quality 801 D4 also marks the return to B&W’s portfolio of one of their most iconic model names

Bowers & Wilkins 801 D4 Features:
Turbine Head
B&W’s all-aluminium Turbine Head is an inert housing for the midrange cone that avoids unwanted resonances and is decoupled from both the bass enclosure and the tweeter body
Solid-Body Tweeter
New Solid Body Tweeter-on-Top housing features an elongated form with a longer tube loading system, producing an even more free and open sound with high frequencies
Reverse Wrap cabinet
The 800 Series Diamond cabinets are formed from one continuous curve, backed by a spine of solid aluminium, so sound dispersion is improved and cabinet reflection is reduced
Matrix
Every model in the new 800 Series Diamond benefits from an upgraded Matrix™ design, reducing resonance and creating a more believable soundstage
Biomimetic Suspension
We’ve turned our attention to another crucial element in a loudspeaker cone: the fabric spider. Our all-new Biomimetic Suspension revolutionises midrange cone performance by greatly reducing the unwanted air pressure and colouration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible
Continuum cone™
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone
Decoupled Midrange assembly
Every 800 Series Diamond loudspeaker aside from the 805 D4 has a decoupled midrange cone ensuring minimal interference from the loudspeaker’s bass drivers
Aluminium top-plate
Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet design with an all-new aluminium top section for even greater stiffness
Crossover
All stereo models in the new range now use rear-mounted crossovers that isolate the sensitive capacitors from the effects of air pressure within the enclosure
Leather by Connolly
The top section is covered in all-new Leather by Connolly trim selected to suit each cabinet finish.
