The benchmark among high-end standmount speakers
The Bowers & Wilkins 805 D4 represents the pinnacle of stand-mounted speakers in the prestigious 800 Diamond Series. Designed to deliver world-class sound reproduction, it combines a Diamond Dome tweeter , Continuum™ mid-bass driver, a reinforced cabinet, and construction solutions derived from the range's flagship models.

Compact in size but extraordinary in performance, the 805 D4 guarantees precise imaging, a three-dimensional soundstage, and reference-level tonal neutrality. Ideal for high-fidelity listening environments or high-end stereo systems, it is the perfect speaker for those who want maximum quality in a bookshelf format without compromise.
Diamond technology and absolute precision
At the heart of the 805 D4 is the renowned 25mm Diamond Dome tweeter , housed in an elegant solid body tweeter-on-top enclosure made from solid aluminium, designed to eliminate unwanted resonances and improve dispersion.
The 165mm mid-bass uses the Continuum™ cone, developed to offer superior transparency and control over traditional Kevlar cones. The cabinet employs a reverse wrap construction with a reinforced front panel and internal Matrix™ technology to reduce vibration and coloration.
The result is an extremely articulated dynamic response, controlled bass and an incredibly natural midrange, with high-frequency extension that pushes the limits of hearing.
