Reference 800 Series Diamond Performance in a More Compact Turbine Head Design
The Bowers & Wilkins 803 D5 Reference Tower Loudspeaker (Pair) delivers much of the engineering sophistication of the larger 800 Series Diamond models in a more room-friendly floorstanding design. As the most compact model in the range to feature Bowers & Wilkins' iconic Turbine Head, the 803 D5 combines a 1-inch Diamond dome tweeter, 5-inch Continuum Cone FST midrange and dual 7-inch Aerofoil bass drivers for highly detailed, spacious and authoritative reproduction.
Advanced cabinet engineering helps the 803 D5 extract more performance from every driver. The Solid Body Tweeter-on-Top isolates the Diamond dome from the main enclosure, while the dedicated midrange operates inside the rigid Turbine Head with Biomimetic Suspension and an Anti-Resonance Plug. Enhanced Matrix bracing, aluminum Space Frame reinforcement, an aluminum top plate and the curved reverse-wrap cabinet further suppress unwanted resonance, allowing the 803 D5 to deliver reference-quality sound with exceptional clarity, imaging and control.
Highlights & Benefits
-
Compact Turbine Head Reference Design — The 803 D5 is the most compact 800 Series Diamond model to use Bowers & Wilkins' dedicated Turbine Head architecture.
-
Diamond Dome Tweeter — The 25mm Diamond dome extends its break-up frequency to approximately 70kHz, helping produce exceptionally open, precise and low-distortion high frequencies.
-
Continuum Cone FST Midrange — A dedicated 130mm Continuum Cone midrange uses FST technology, Biomimetic Suspension and an Anti-Resonance Plug for natural, highly detailed reproduction of voices and instruments.
-
Dual 7" Aerofoil Bass Drivers — Twin 180mm Aerofoil-profile woofers combine deep low-frequency extension with speed, control and impressive dynamic capability.
-
Enhanced Matrix Cabinet Construction — Matrix bracing, aluminum Space Frame reinforcement and the curved cabinet architecture reduce resonance and create a more stable platform for the drive units.
Technology & Design
Diamond Dome & Solid Body Tweeter-on-Top — The Diamond dome tweeter is mounted in its own rigid, elongated enclosure above the main cabinet, reducing diffraction and isolating the high-frequency driver from cabinet vibration for cleaner imaging and greater openness.
Continuum Cone FST & Turbine Head — The 5-inch Continuum Cone midrange sits inside the acoustically optimized Turbine Head and uses Bowers & Wilkins' Biomimetic Suspension and Anti-Resonance Plug to reduce unwanted mechanical and acoustic interference.
Twin Aerofoil Bass Cones — Two 7-inch Aerofoil-profile bass drivers use variable-thickness cone geometry engineered to deliver high rigidity with controlled mass, producing powerful bass without sacrificing articulation or transient speed.
Matrix, Space Frame & Aluminum Top Plate — Enhanced internal Matrix bracing works with aluminum structural reinforcement and a damped aluminum top section to create an exceptionally rigid enclosure and reduce energy storage within the cabinet.
FAQ — Bowers & Wilkins 803 D5
Is the Bowers & Wilkins 803 D5 sold as a pair?
This listing is for one stereo pair of Bowers & Wilkins 803 D5 reference floorstanding loudspeakers.
How much amplifier power is recommended for the 803 D5?
Bowers & Wilkins recommends 50 to 1000 watts per channel into 8 ohms with unclipped program material. Because the impedance can fall to 3.0 ohms, high-quality amplification with strong current delivery is recommended for extracting the speaker's full performance.
What is the difference between the 803 D5 and 802 D5?
Both use Bowers & Wilkins' Diamond dome tweeter and Turbine Head architecture, but the 803 D5 uses a smaller 5-inch Continuum midrange and dual 7-inch Aerofoil bass drivers. The larger 802 D5 uses a 6-inch midrange and dual 8-inch bass drivers, providing greater low-frequency scale and overall output capability.
Is the 803 D5 suitable for home theater as well as two-channel listening?
Yes. The 803 D5 is an excellent choice for both reference stereo systems and high-performance home theaters, especially when combined with other 800 Series Diamond speakers for consistent tonal character across the system.
