About the 804D
The 804D is part of Bowers & Wilkins' 800 Series Diamond line, designed for audiophiles seeking exceptional sound quality with a more conventional aesthetic. It features a three-way vented-box system with a 25mm diamond dome tweeter, a 150mm Continuum cone FST midrange driver, and two 165mm Aerofoil cone bass drivers. The cabinet uses a reverse wrap design made from a continuous curved wood section for enhanced stiffness and reduced resonance. The speaker includes advanced technologies such as the Solid Body Tweeter-on-Top, Anti-Resonance Plug, Biomimetic Suspension for the midrange driver, Matrix cabinet construction, and a downward-firing Flowport exiting onto a solid aluminium plinth with steel constrained layer damping. It has a frequency response of 24Hz to 28kHz ±3dB, sensitivity of 89dB, nominal impedance of 8Ω (minimum 3Ω), and recommended amplifier power of 50W to 200W. Dimensions are 1071mm height, 306mm width, and 391mm depth, with a net weight of 36.85kg. Available finishes include Gloss Black, White, Satin Rosenut, and Satin Walnut with grille options in black or grey.
