Excellence. Evolved.

This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. The benchmark, the icon; the most advanced range of loudspeakers B&W knows how to make.

For listeners who crave the performance of an 800 Series Diamond loudspeaker but prefer a more conventional aesthetic, the 804 D4 is the perfect choice. Its new reverse-wrap cabinet follows the proven design principles established by its larger siblings and its new plinth ensures rock-solid, accurate bass response too.

Solid Body Tweeter

The latest incarnation of B&W's iconic 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. As before, the carefully decoupled housing is milled from a single solid block of aluminium to better resist resonance.

Reverse Wrap cabinet

Instead of a flat-fronted speaker with a curving back, B&W cabinets are formed from one continuous curve, held together with a spine of solid aluminium. Fewer joins make for a stiffer, more inert structure, and a curved front means less baffling around the drive units. So sound dispersion is improved, and cabinet reflection is reduced.

Matrix

Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. Every model in the new 800 Series Diamond benefits from an upgraded Matrix design that combines solid plywood construction with aluminium bracing to reinforce key stress points.

Biomimetic Suspension

Now, B&W has turned their attention to another crucial element in a loudspeaker cone: the fabric spider. The all-new Biomimetic Suspension revolutionizes midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible.

Diamond Dome Tweeter

Its unique stiffness-to-lightness ratio makes diamond the perfect tweeter material. B&W's diamond domes are capable of unrivaled acoustic detail, naturalism and spaciousness.

Continuum cone

Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. The result is a more open, neutral performance that delivers voices and instruments with precision and transparency.

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. The same design also provides a perfect mounting point for all-new Leather by Connolly cabinet detailing, with luxurious black leather for dark cabinets and light grey for lighter finishes.

Aluminum Plinth

A great speaker needs a rock solid foundation. The 804 D4 now joins the other floor-standing models in the range by offering a downwards-firing Flowport, exiting on to a new, stiffer solid aluminum plinth complete with a constrained layer steel damping sheet offering a rock-solid foundation that controls unwanted resonance. It also has greatly upgraded spikes for maximum stability.

Decoupled Midrange assembly

Every 800 Series Diamond loudspeaker aside from the stand-mount 805 D4 has a dedicated midrange cone using four key Bowers & Wilkins technologies: the Continuum cone, FST , Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker’s bass drivers.

Crossover

All stereo models in the new 800 Series Diamond range now use rear-mounted crossover designs mounted on stiff aluminium spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use.

Leather by Connolly

The top section of every stereo model features an aluminium top-plate, covered in all-new Leather by Connolly trim. B&W uses luxurious, full-grain black leather for Gloss Black and Satin Rosenut finishes, and a light grey leather for White and Satin Walnut.
