Towering ahead

Thanks to a brand-new cabinet and aluminium plinth, this is the highest performing 804 from Bowers & Wilkins. If you desire the sound and performance of the 800 series floor-stander but prefer more conventional looks - then this is the perfect choice for you. Available in four different finishes.


Classic quality

804 D4 is perhaps more conventional in appearance than other floorstanders in the 800 Series Diamond range, but it’s 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.


Aluminium top-plate

Every stereo model in the new 800 Series Diamond range 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 leather for dark cabinets and light grey for lighter finishes.


Reverse Wrap cabinet

Instead of a conventional loudspeaker box, the cabinet in 804 D4 is made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.


Aluminium plinth

A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminium plinth complete with a steel constrained layer damping sheet, which controls unwanted resonance. It also has greatly upgraded spikes for maximum stability and durability.


Refined Design

Refined, elegant cabinet proportions plus luxurious, premium detailing combine to make this the most premium 800 Series Diamond range yet. The first and most obvious change is the addition of a fourth finish to the line-up. The new range now includes a Satin Walnut finish, joining the established selection of Gloss Black, White and Satin Rosenut. Every stereo model in the range also enjoys a significantly upgraded cabinet design with an all-new rigid, cast aluminium top section – replacing the previous wooden version – to offer even greater stiffness and thus improve cabinet quietness still further. In a luxurious touch, the profile of the new aluminium top is finished in ‘Leather by Connolly’ – in black for dark cabinets (Black, Satin Rosenut) and light grey for lighter finishes (White, Satin Walnut).
 
Every model in the range adopts a revised version of the iconic Solid Body Tweeter-on-Top housing, with a new, elongated tube-loading system to produce an even more open sound for high frequencies. This supremely stiff enclosure deftly resists unwanted resonance and is an exceptional acoustic form – especially when combined with a new two-point decoupling system that isolates it from the rest of the loudspeaker more effectively than ever. As before, the Solid Body Tweeter is milled from a single solid block of aluminium and now, it uses an anodised finish, either dark or light depending on the cabinet colour, to celebrate that fact.
 
Finally, the range introduces three entirely new cabinet forms. The 805 D4 and 804 D4 stereo models adopt the reverse-wrap cabinet design first introduced in 2015 for the larger speakers in the series. This new form reduces the profile of each cabinet’s front baffle while dramatically increasing the overall rigidity of the complete system. It also allows crossovers to now be mounted in dedicated spaces on the rear of each speaker, housed behind the rigid aluminium spines.The 804 D4 builds on the potential of its new configuration by adding a downward-firing port with an integral aluminium plinth – again, much like the form used by the larger floorstanding speakers in the range. Alongside the 805 D4 and 804 D4, the all-new HTM82 D4 centre speaker adopts the reverse-wrap cabinet form of its siblings, for superior acoustic and mechanical performance.
