804 D3 - Imperious performer
Straight up great sound
Featuring cutting edge technology, the B&W 804 D3 delivers incredibly high-performance sound in a traditional loudspeaker form with a smaller footprint. The ultra-rigid cabinet plays host to a Diamond Dome tweeter Continuum cone midrange and Aerofoil bass drivers. All of these come together to generate room filling, highly detailed performance.
The 800 Series isn’t just another speaker range. For decades, it’s served as the benchmark for high-end audio performance. So how do you improve on the best? Answer: you start from the beginning. So when we set out to create the new 800 Series Diamond, we went back to the drawing board, embarking on one of the most ambitious research and development projects we have ever undertaken.
Using new computer modelling techniques, we examined every single element of the speaker, searching for the smallest weaknesses so we could understand how to overcome them. As a result, almost every component of every speaker has been reimagined from the ground up, from drive unit materials all the way to the position of screw fixings. The new 800 Series Diamond isn’t an evolution. It’s a revolution.
Wolf in sheep’s clothing
It might have a more traditional appearance than other speakers in the range, but don’t let that fool you. The 804 D3 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.
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.
Solid body tweeter
Vibration is the enemy of good sound. To minimise vibrations, you need components that are as stiff as possible. For the 800 Series Diamond, we created our 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.
For decades, we thought that nothing could beat Kevlar as a midrange 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 behaviour 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.
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
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.
A great speaker needs a rock-solid foundation. By moving the crossover from the plinth to the main body of the speaker, we’ve been able to create a base for the 800 Series Diamond that’s more stable and resonance-resistant than ever. Replacing the original open-box design, the new plinth is constructed from a solid piece of aluminium weighing in at a mighty 17kg. This improves stability by lowering the centre of mass and counter-balancing the weight of the Turbine head.
