The new 800 Series Diamond range continues to feature seven models, beginning with the two-way 805 D4 stand-mount speaker, joined by a series of three-way floorstanding models, including the 804 D4, 803 D4 and 802 D4. For the flagship model in the range, Bowers & Wilkins reintroduced an iconic name to its portfolio, with the launch of 801 D4 to replace the existing 800 D3. For home theater use, the HTM81 D4 and HTM82 D4 provide a pair of high-performance center channel speakers to complete the range.
Every stereo model in the range enjoys a significantly upgraded cabinet design with an all-new rigid, cast aluminum top section – replacing the previous wooden version – to offer even greater stiffness and thus improve cabinet quietness still further, the company says. In a luxurious touch, the profile of the new aluminum top is finished in "Leather by Connolly" and a revised version of the iconic Solid Body Tweeter-on-Top housing, with a new, elongated tube-loading system.
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.
The new series feature the Continuum Cone technology for their midrange and mid/bass drivers, along with the Fixed Suspension Transducer (FST) midrange technology, combined with an all-new advance that transforms the other key element of a drive unit’s normal operation: the fabric spider. The all-new composite Biomimetic Suspension replaces the conventional fabric spider with a minimalist composite suspension system that, according to B&W revolutionizes midrange cone performance by greatly reducing unwanted air pressure. For the woofers, the Aerofoil Cone, a composite bass cone with a varying thickness designed to offer maximum stiffness where it is most needed while preserving a low mass – thanks to its carbon-fiber skin and light syntactic foam core is used.
All the above are combined with careful isolation of the complete midrange assembly from the rest of the surrounding cabinet at all three-way models of the series, using sprung-mounted decoupling mounts, further restricting the flow of vibration into the assembly. Finally, 803 D4, 802 D4 and 801 D4 include the massively stiff all-aluminum Turbine Head enclosure for their midrange drive units, providing not only an outstanding acoustic form but also even better isolation – since the head assembly is itself further decoupled from the bass enclosure below.
The new 800 Series Diamond introduces a revised version of the iconic Solid Body Tweeter housing; this continues to be machined from a solid piece of aluminum, but now it features an elongated form (almost 30cm long) with a longer internal tube-loading system. The new Solid Body Tweeter assembly is now decoupled from the speaker body or Turbine Head (depending on model) in two locations rather than one.
For the cabinets, the well-known Matrix architecture is used, where an internal structure of interlocking panels that brace the loudspeaker internally in all directions.
