Bowers & Wilkins will have its hi-end fans salivating at the sight and sounds of its new 800 Series Signature, described as the ultimate versions of its acclaimed 800 Series Diamond loudspeaker range.

Starting with the new 801 D4 Signature which ups the ante of its already reference-standard 801 D4 adding powerful twin 250mm (10”) Aerofoil Cone bass drivers with upgraded and improved magnets to their motor systems.

It also gets an enhanced aluminium top plate beneath its Turbine Head midrange enclosure using an optimised skeletal structure and carefully placed damping material to reduce unwanted resonance from the top of the enclosure.

Elsewhere its tweeter sports a new FEA-optimised grille mesh to allow more energy from the Diamond Dome tweeter into the room, while protecting the diaphragm.
