Bowers & Wilkins 802 D4 Floor Stand Loudspeakers
The Bowers & Wilkins 802 D4 is a reference-grade floorstanding loudspeaker from the 800 Series Diamond, combining advanced driver technologies with a highly engineered enclosure designed for exceptionally detailed and controlled reproduction. Positioned below the flagship 801 D4, the 802 D4 incorporates many of the same core technologies, including the Turbine Head enclosure for its midrange drive unit.
The 802 D4 features a three-way vented-box architecture, combining a Diamond dome tweeter, a 150mm Continuum cone FST midrange and two 200mm Aerofoil cone bass units. Bowers & Wilkins also incorporates its Matrix enclosure technology, Anti-Resonance Plug, Biomimetic Suspension, Flowport and Solid Body Tweeter-on-Top design.
Designed for reference-grade stereo listening and also well suited to high-end home theatre applications, the 802 D4 brings together sophisticated acoustic engineering with a choice of premium cabinet finishes. Its aluminium top-plate further increases cabinet stiffness, while the dedicated midrange assembly is decoupled from the bass enclosure to minimise interference from the bass drivers.
