SOLID BODY TWEETER
Solid body tweeter Vibration is the enemy of good sound. To minimize vibrations, you need components that are as stiff as possible. For the 800 Series Diamond, that B&W has created with their stiffest tweeter enclosure yet. The tweeter assembly for the new range is housed in a solid piece of aluminium, while an improved gel decoupling system isolates the tweeter from the effects of cabinet resonance. The result? Pin-sharp acoustic detail, and new levels of insight into a musical performance.
We want to experience it – in its purest, most unadulterated form. To savor every nuance and detail. To feel as close to a musical performance as if we were there, with the artist at the moment it was recorded. At Bowers & Wilkins, we’ve been pursuing this dream for half a century. And now, they've created their biggest leap forward yet. Welcome to the 800 Series Diamond.
It might have a more traditional appearance than other speakers in the range, but don’t let that fool you. The 805 D4 delivers incredible acoustic transparency, thanks to unique 800 Series Diamond features such as our Continuum cone and augmented Matrix bracing system. So while its looks may be conventional, its performance is anything but.
Hear the sound, not the cabinet. That’s the principle behind 800's separate head units – a feature introduced when B&W has launched their first 800 Series speaker in 1979. Now, thanks to a radical redesign, the 800 Series Diamond head unit performs better than ever. Constructed from a single piece of aluminium, braced with internal radial fins and with a raised, slimmer profile, the Turbine head is almost totally inert, producing a sound that’s free from cabinet coloration.
For decades, we thought that nothing could beat Aramid Fibre as a mid range cone material. But now, following eight years of intensive development, we’ve finally come up with something even better. Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. The result is a more open, neutral performance. And a giant leap forward for loudspeaker design.
Sometimes, new technologies allow us to achieve things in engineering that wouldn’t have been possible a few years ago. The Aerofoil bass cone is a perfect example. By using advanced computer modeling and a new syntactic core material, we’ve been able to produce a cone of varying thickness, with maximum stiffness where it’s needed most. This optimised shape means the cone displays pistonic behaviour further up the audible range, producing bass that’s precise, controlled and utterly lifelike.
Reverse Wrap Cabinet
When it came to designing the ideal shape for the 800 Series Diamond cabinet, we did a U-turn. Quite literally. Instead of a flat-fronted speaker with a curving back, we produced a cabinet with a front and sides formed of one continuous curve, held together with a spine of solid aluminium. 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.
Matrix provides the backbone for our speakers. It’s an internal structure that works like the bracing of a ship’s hull, with criss-crossed interlocking panels keeping our cabinets rigid and inert. For the 800 Series Diamond, we’ve introduced our most radical rethink of the Matrix concept yet. The internal panels are thicker, solid plywood has replaced MDF, and metal components have been added to reinforce key stress points. All together it’s the most solid Matrix system we’ve ever built.
