Bowers & Wilkins 803 D4 – Floorstanding Tower Speaker
Bowers & WilkinsThis 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. For us, the 800 Series Diamond is everything we know, and everything we are. The loudspeaker that sets the standard other high-end designs will be judged by for years to come. Our most compact headed model brings all the technical advantages of a dedicated midrange enclosure - the Turbine™ Head, with its decoupled midrange cone - to a smaller footprint that's easily accommodated in any home.
Key Technologies
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. Fifteen years after we introduced it, we haven't found a better tweeter dome technology.
Solid Tweeter Housing
Our Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system and an all-new design of tweeter grille, producing an even more free and open sound with high frequencies.
The ultimate Matrix™
Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. The Matrix assembly in 802 D4 is our best yet, upgraded with extensive aluminum bracing to reinforce key stress points.
Turbine™ Head
The all-aluminum Turbine Head houses our Continuum midrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances. At the same time, it’s decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.
Biomimetic Suspension
Sometimes, making a big difference takes unconventional thinking. Our new Biomimetic Suspension revolutionizes midrange performance by greatly reducing the unwanted air pressure and coloration that a traditional fabric spider can generate. The result? Midrange transparency you wouldn’t believe.
Aerofoil™ Drivers + Anti Resonance Plug
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-fiber skin and variable-profile foam core. Now, we have added the foam Anti-Resonance Plug for lower distortion and even cleaner bass.
Aluminum top-plate
Every stereo model in the new 800 Series Diamond™ range has a significantly upgraded cabinet with an all-new aluminum 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.
Decoupled midrange assembly
Like its tower speaker siblings in the new range, 803 D4 has a dedicated midrange cone using three key Bowers & Wilkins technologies: the Continuum™ cone, Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker’s bass drivers.
