Standlautsprecher 804 D4
BOWERS & WILKINS
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. For us, the 800 Series Diamond is everything we know, and everything we are.
For listeners who prefer a rnore conventional aesthetic but crave the performance of an 800 Series Diarnond loudspeaker, the 804 D4 is the perfect choice. lts new reverse -wrap cabinet follows the proven design principles established by its larger sib ling s.
Our cabinets are formed from one continuous curve, backed by a spine of solid aluminium, so sound dispersion is improved, and cabinet reflection is reduced.
804 D4 is massively upgraded next to 804 D4. Its stiff reverse-wrap cabinet design features a full-length aluminium plate behind the baffle, an aluminium top section detailed with Leather by Connolly and a new rear-mounted crossover enclosure. Its port now fires downwards rather than forwards on to an all-aluminium plinth and, as with all three-way speakers in the new range, its midrange drive unit features our revolutionary Biomimetic Suspension.
Reverse Wrap Cabinet
Every model in the new 800 Series Diamond now uses our reverse-wrap cabinet technology, including even the smallest models in the range. Instead of a conventional loudspeaker box, our cabinets are made from a continuous curved section of wood, with only the smallest possible gap at the rear of the cabinet to allow for parts to be inserted into the enclosure. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound by reducing the baffling effect.
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.
A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport™ exiting on to a solid aluminium plinth cornplete with a steel constrained layer darnping sheet, which controls unwanted resonance. lt also has greatly upgraded spikes for rnaxirnurn stability.
