For listeners who crave the performance of an 800 Series Diamond floorstander but prefer a more conventional aesthetic, the Bowers and Wilkins 804 Diamond D4 Speakers are the perfect choice. Its new cabinet and plinth make it our best-performing 804 yet.
Classic Quality
The 804 Diamond D4 is perhaps more conventional in appearance than other floorstanders in the 800 Diamond range, but itโs every bit as sophisticated. Its new Reverse-Wrap cabinet is both a mechanical and acoustic revolution in its class, and its new plinth ensures rock-solid, accurate bass response too.
Aerofoil Bass Cone
Our Aerofoil bass cone technology remains an outstanding solution to combining low mass and high stiffness in bass cones, thanks to its carbon-fibre skin and variable-profile foam core. Now, we have added the foam Anti-Resonance Plug for lower distortion and even cleaner bass from the 804 Diamond D4.
Biomimetic Suspension
Sometimes, making a big difference takes unconventional thinking. The new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and colouration that a traditional fabric spider can generate. The result? The 804 Diamond D4 has midrange transparency that you wouldnโt believe.
Aluminium Top-plate
The 804 Diamond D4 has a significantly upgraded cabinet with an all-new aluminium top-plate. This also provides a perfect mounting point for all-new Leather by Connolly trim, with luxurious black or light grey finishes.
The Science of Sound
Innovation is at the heart of everything we do. We question, we examine, we understand, and then we evolve. Bowers and Wilkins use computer modelling to explore and reimagine every aspect of the 804 Diamond D4 speaker design.
