Description
A new statement in floorstanding loudspeakers
The larger model in the new Signature range is the 801 D4 Signature, a powerful three-way floors tanding loudspeaker that builds on the specification of the iconic 801 D4 as found in Abbey Road Studios. Based on the brand’s Diamond Dome tweeter and Continuum™ Cone FST™ midrange drive unit, the 801 D4 Signature adds powerful twin 250mm (10”) Aerofoil Cone bass drivers with upgraded and improved magnets to their motor systems relative to the 801 D4 model. It also includes a radically enhanced aluminium top plate beneath its Turbine Head midrange enclosure; this new design uses a new optimised skeletal structure and carefully placed damping material to significantly reduce unwanted resonance from the top of the enclosure. The result is even more midrange transparency and openness to the already outstanding performance of the 801 D4.
The port output on 801 D4 Signature has received similarly significant upgrades; it is now cast from aluminium, creating a stiffer and quieter structure that is less prone to unwanted port noise. In combination with the updated Aerofoil Cone bass drivers, this results in even cleaner, lower distortion and more accurate sounding bass. As with all Signature models over the years, the 801 D4 Signature benefits from careful upgrades to its crossover aimed at further increasing transparency with new and upgraded bypass capacitors for every element of the assembly. Finally, the 801 D4 Signature introduces a new FEA-optimised design of tweeter grille mesh that builds on the already impressive transparency offered by existing Bowers &
Wilkins loudspeakers. The new mesh provides a new superior blend of transparency and stiffness, allowing even more energy from the Diamond Dome tweeter into the room, while guarding the diaphragm against unwanted damage.
Exclusivity celebrated
To properly identify their prestigious position within the Bowers & Wilkins portfolio, both the 801 D4 Signature and 805 D4 Signature are only available in two exclusive new finishes. The Midnight Blue Metallic paint is the same as offered on the iconic Nautilus loudspeaker, featuring a total of eleven coats of paint and lacquer that are machine polished to a gleaming and lustrous finish. Excluding curing times, the paint application process alone is in excess of 18 hours of labour. Midnight Blue Metallic loudspeakers are further celebrated with a bespoke blue Leather by Connolly trim on the top plate.
Alternatively, both models can be purchased in an exceptional California Burl Gloss wood veneer, featuring unique wood figuring and a luxurious high gloss finish trimmed in black Leather by Connolly. The wood veneer is sustainably sourced engineered wood from Italian specialist, ALPI. Including no less than fourteen coats of lacquer and multiple sanding processes, the total finishing time for a single 801 D4 Signature in California Burl Gloss is in excess of 24 hours.
