The new 800 Series Diamond features a host of product developments and technological innovations that evolve both performance and design, further establishing the 800 Series Diamond as the finest loudspeakers on the market. The best just got better.
Diamond dome tweeter technology remains at the heart of 800 Series Diamond. Exceptionally stiff yet incredibly light, diamond pushes break-up frequency to an extraordinary 70kHz – far beyond human hearing – delivering outstanding clarity, precision and openness. Grown using advanced chemical vapour deposition, each dome ensures unrivalled detail and natural sound reproduction.
Hear the sound, not the cabinet. Our all-aluminium Turbine Head is a phenomenally stiff and inert housing for the crucial midrange cone, carefully damped to avoid unwanted resonances and decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.
The latest incarnation of our iconic Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system and an all-new design of tweeter grille that has been optimised to produce an even more free and open sound with high frequencies. As before, the carefully decoupled housing is milled from a single solid block of aluminium to better resist resonance.
Matrix™ bracing uses interlocking panels to reinforce the internal walls of loudspeaker cabinets in all directions, 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.
Instead of a flat-fronted speaker with a curved back, 800 Series Diamond cabinets are formed from a single continuous curve, locked in place by a solid aluminium spine. Fewer joins make for a stiffer, more inert structure, and a curved front means less baffling around the drive units. So sound dispersion is improved, and cabinet reflection is reduced.
We’ve turned our attention to another crucial element in a loudspeaker cone: the fabric spider. Our Biomimetic Suspension revolutionises midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible.
Every 800 Series Diamond loudspeaker, aside from the standmount 805 D5, has a dedicated midrange cone using four key Bowers & Wilkins technologies: the Continuum cone, FST™, Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker’s bass drivers.
Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet design with an all-new aluminium top section for even greater stiffness. The same design also provides a perfect mounting point for all-new Leather by Connolly cabinet detailing, with luxurious black leather for dark cabinets and light grey for lighter finishes.
820 Series Diamond use upgraded rear-mounted crossover designs mounted on stiff aluminium spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use.
Thanks to its composite construction, the Continuum™ cone avoids the abrupt transitions in behaviour that can impair the performance of a conventional drive unit. The result is a more open, neutral performance that delivers voices and instruments with precision and transparency.
The top section of every stereo model features an aluminium top-plate, covered in all-new Leather by Connolly trim. We use luxurious, full-grain black leather for the Stealth Black and Dark Walnut finishes, and light grey leather for Warm White and Light Walnut.
Featuring upgraded motor systems derived from the acclaimed Signature range of loudspeakers, the new bass/mid, midrange and bass drive units in all of the new 800 Series Diamond D5 models deliver a cleaner, lower-distortion sound for a more accurate and revealing presentation.
The aluminium plinths on all 800 Series Diamond floorstanding models include constrained-layer damping, plus tuned-mass dampers that are individually optimised to the mechanical resonances of each individual speaker. The result is lower unwanted cabinet-borne coloration and cleaner low-frequency output.
In a further improvement to the massively stiff enclosure in the 800 Series Diamond range, the new D5 models introduce aluminium Space Frame Bracing rails to the rear of each cabinet. These highly stiff constructions further fortify the cabinet against unwanted mechanical vibration, contributing to an even more spacious and immersive soundstage.
