How do you improve on the world’s most successful and iconic range of high-end loudspeakers? It’s a challenge that has occupied the past six years for the finest minds at SRE, home of the world-renowned Bowers & Wilkins engineering team. Their solution is to combine continuous improvement of every component in each design with innovative and proprietary technology that re-imagines the fundamental basics of a conventional loudspeaker drive unit: the new, unique and revolutionary Biomimetic Suspension.
Bowers & Wilkins 800 Series Diamond range continues to feature seven models, beginning with the two-way 805 D4 stand-mount speaker. That’s joined by a series of three-way floor-standing models, including the 804 D4, 803 D4, and 802 D4. For the flagship model in the range, Bowers & Wilkins is pleased to reintroduce an iconic name to its portfolio, with the launch of 801 D4 to replace the existing 800 D3. For home theatre use, the HTM81 D4 and HTM82 D4 provide a pair of high-performance centre channel speakers to complete the range.
Every new model in the range combines hundreds of detail improvements plus several entirely new technologies to create the most transparent, detailed, and natural-sounding series of loudspeakers Bowers & Wilkins has ever produced.
Refined, elegant cabinet proportions plus luxurious, premium detailing combine to make this the most premium 800 Series Diamond range yet.
The first and most obvious change is the addition of a fourth finish to the line-up. The new range now includes a Satin Walnut finish, joining the established selection of Gloss Black, White, and Satin Rosenut.
Every stereo model in the range also enjoys a significantly upgraded cabinet design with an all-new rigid, cast aluminium top section – replacing the previous wooden version – to offer even greater stiffness and thus improve cabinet quietness still further. In a luxurious touch, the profile of the new aluminium top is finished in ‘Leather by Connolly’ – in black for dark cabinets (Black, Satin Rosenut) and light grey for lighter finishes (White, Satin Walnut).
Every model in the range adopts a revised version of the iconic Solid Body Tweeter-on-Top housing, with a new, elongated tube-loading system to produce an even more open sound for high frequencies. This supremely stiff enclosure deftly resists unwanted resonance and is an exceptional acoustic form – especially when combined with a new two-point decoupling system that isolates it from the rest of the loudspeaker more effectively than ever. As before, the Solid Body Tweeter is milled from a single solid block of aluminium and now, it uses an anodised finish, either dark or light depending on the cabinet color, to celebrate that fact.
Finally, 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. It also allows crossovers to now be mounted in dedicated spaces on the rear of each speaker, housed behind the rigid aluminium spines.
The 804 D4 builds on the potential of its new configuration by adding a downward-firing port with an integral aluminium plinth – again, much like the form used by the larger floor-standing speakers in the range. Alongside the 805 D4 and 804 D4, the all-new HTM82 D4 centre speaker adopts the reverse-wrap cabinet form of its siblings, for superior acoustic and mechanical performance.
