Description
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.
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.
800 Series Diamond
This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is our benchmark, our icon; the most advanced range of loudspeakers we know how to make, equipped with all of our most sophisticated technologies and designed to deliver the upmost in sonic realism. For us, the 800 Series Diamond is everything we know, and everything we are.
Diamond Dome Tweeter
One of our most significant accomplishments over the past two decades, the ultra-stiff, supremely accurate Diamond dome tweeter is the perfect combination of low mass, exceptional stiffness and outstanding accuracy. 15 years after we introduced it, we haven’t found a better tweeter dome technology.
Solid Body Tweeter Assembly
The latest incarnation of our 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, our 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
Sometimes, making a big difference takes unconventional thinking. For decades, we thought nothing could improve on the sound of our famous yellow Aramid Fibre midrange cones, but eventually our Continuum cone technology changed our minds. Now, we’ve turned our attention to another crucial element in a loudspeaker cone: the fabric spider.
Our 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.
Continuum cone
Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behaviour 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.
Aerofoil™ bass cone
Our Aerofoil bass cone technology remains an outstanding solution to the conundrum of 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.
Decoupled Midrange assembly
Every 800 Series Diamond loudspeaker (aside from the standmount 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.
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.
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.
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. We use luxurious, full-grain black leather for Gloss Black and Satin Rosenut finishes, and a light grey leather for White and Satin Walnut.
Get a Head
804 D4 is the conventional floorstanding model in the 800 Series Diamond range. Step up to 803 D4 and you’ll find larger bass drivers (180mm, 7in) plus, crucially, the addition of a Turbine™ Head enclosure for the 130mm (5in) midrange cone, which adds even more spaciousness to the sound.
