First look at all new Bowers & Wilkins speakers - 802 D4
The world’s best loudspeaker range introduces all-new industrial design plus a range of breakthrough technologies to set even higher standards for outright sound quality.
The new 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.
New technologies
Continuum™ Cone, FST & Biomimetic Suspension
The result of an eight-year research programme, the composite Continuum Cone - used for both midrange and mid/bass applications - is already famed for its open, transparent, and neutral performance. When used as a midrange drive unit in Bowers & Wilkins floor-standing speakers, it is always combined with our Fixed Suspension Transducer (FST) midrange technology, which carefully avoids the colouration that traditional cone surrounds can introduce.
Now, Bowers & Wilkins has combined the twin benefits of Continuum and FST with an all-new advance that transforms the other key element of a drive unit’s normal operation: the fabric spider. Over decades of continuous development to nearly all areas of speaker design, the fabric spider, a key element in the suspension of every conventional loudspeaker drive unit, has remained largely unchanged - until now.
The all-new composite Biomimetic Suspension replaces the conventional fabric spider with a minimalist composite suspension system that revolutionises midrange cone performance by greatly reducing unwanted air pressure - aka sound - that a conventional fabric spider can generate, removing its unpredictable, non-linear effects. The result is unprecedented midrange transparency and realism.
Decoupled Midrange & Turbine™ Head
Bowers & Wilkins combines all the performance-enhancing benefits of its Continuum Cone, FST midrange technology and Biomimetic Suspension with careful isolation of the complete midrange assembly from the rest of the surrounding cabinet. In all three-way models, midrange drive units include a highly stiff
all-aluminium chassis featuring Tuned Mass Dampers (TMD) to quieten any resonance. These complete drive units and motor systems are then isolated on 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-aluminium 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 HTM81 D4 and HTM82 D4 introduce a new and similar concept but inside their cabinets: each
centre-channel model now features an internal aluminium enclosure that provides a stiff, well-isolated housing for the midrange drive unit and its decoupling mechanism.
Solid-Body Tweeter
To minimise the unwanted transfer of resonance into each model’s Diamond Dome tweeters, an exceptionally stiff enclosure is required. 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 aluminium, but now it features an elongated form (almost 30cm/12in 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: this notably improves spaciousness and openness. At the same time, the tweeter’s motor assembly has been re-engineered to allow the drive unit to ‘breathe’ more effectively with no loss of performance. The result is a notable reduction in the resonant frequency.
