Bowers & Wilkins 805 D4 Signature (Paire)

Description

Signature Technology

As with preceding generations of Signature, both 805 D4 Signature and 801 D4 Signature employ a series of carefully engineered audio upgrades designed to deliver the best possible sound. These changes take in structural modifications designed to improve mechanical behavior and acoustic transparency, drive unit enhancements aimed at delivering even greater resolution and crossover upgrades that ensure fully optimized performance from the complete system.

Aluminum Top-Plate 

A new aluminum top plate features a series of machined-out holes in the structure, strategically positioned to change the resonant frequency of the aluminum.

New Tweeter Grille Mesh

Both models introduce a new design of tweeter grille mesh. The new grille mesh offers a carefully optimized combination of stiffness – necessary to protect the fragile dome from unwanted damage – and openness. The new design is more open than ever, which enhances both resolution and spaciousness. The orientation of the structure is specific and engineered to ensure the best results. Bowers & Wilkins had over 25 iterations in the development process of this new design!

New Mid/Bass for 805 D4 Signature

Bowers & Wilkins take the same approach than they did with the 801 D4 Signature with the mid/bass drive unit on 805 D4 Signature, which also features an upgraded pole on the magnet plus a larger vent hole for improved current distortion.

Upgraded Crossovers

Both 801 Signature and 805 Signature feature upgraded bypass capacitors. These are also doubled-up in quantity across the boards. The result is an even cleaner sound.
