Bowers & Wilkins · 800 Series Diamond D5
The smallest 800 Series speaker with the Turbine Head midrange: true 800 Series imaging in a cabinet that fits a real living room.
Price is for a pair. New for 2026; replaces the 803 D4.
The 803 D5 is where the Turbine Head begins. A 5-inch Continuum Cone midrange sits in its own solid aluminum enclosure, decoupled from the cabinet below, with the Diamond Dome tweeter above it and two 7-inch Aerofoil bass drivers beneath. For D5 the midrange and bass drivers get Signature-derived motor parts, and the cabinet gains rear Space Frame rails, a thicker Matrix and a new tuned plinth.
The payoff of the Turbine Head is focus: voices and instruments float free of the boxes, with the kind of precise, stable stereo image the 800 Series is known for. The 803 still reaches 16 Hz at −6 dB, so it rarely needs help from a subwoofer, and at 90 dB sensitivity it's efficient. Plan on a solid amplifier for its 3.0 Ω minimum impedance. It suits medium-sized rooms.
The top plate is trimmed in Leather by Connolly: black on Stealth Black and Dark Walnut, light grey on Warm White and Light Walnut.
