The Flagship of the Bowers & Wilkins 800 Series Diamond
The Bowers & Wilkins 801 D5 Reference Tower Loudspeaker (Pair) represents the pinnacle of the 800 Series Diamond range, combining Bowers & Wilkins' most advanced driver technologies with an exceptionally rigid and acoustically optimized enclosure. Designed for reference-level two-channel systems, mastering environments and uncompromising home theaters, the 801 D5 combines a 1-inch Diamond dome tweeter, 6-inch Continuum Cone FST midrange and two massive 10-inch Aerofoil bass drivers to reproduce music with exceptional scale, transparency and dynamic authority.
Every major element of the 801 D5 is engineered to reduce unwanted coloration and allow the drive units to operate with greater freedom and precision. The Solid Body Tweeter-on-Top isolates the Diamond dome from the main cabinet, while the Continuum midrange operates within Bowers & Wilkins' distinctive Turbine Head. An upgraded Matrix cabinet structure, aluminum Space Frame Bracing, curved cabinet surfaces and a substantial aluminum plinth provide an exceptionally stable mechanical platform for the twin 10-inch bass system. The result is a reference loudspeaker capable of combining deep, powerful low frequencies with precise imaging, natural midrange reproduction and exceptionally revealing high-frequency detail.
Highlights & Benefits
-
Flagship 800 Series Diamond Performance — The 801 D5 sits at the top of Bowers & Wilkins' reference loudspeaker range and is engineered for the highest levels of accuracy, scale and dynamic performance.
-
Diamond Dome Tweeter — The 25mm Diamond dome extends its break-up frequency to approximately 70kHz, helping deliver exceptionally clean, open and precise high-frequency reproduction.
-
Continuum Cone FST Midrange — A dedicated 150mm Continuum driver combines FST technology, Biomimetic Suspension and an Anti-Resonance Plug for highly controlled reproduction of vocals and instruments.
-
Dual 10" Aerofoil Bass Drivers — Two 250mm Aerofoil-profile woofers provide exceptional low-frequency extension, authority and control, with specified response extending down to 15Hz ±3dB.
-
Advanced Cabinet Architecture — Matrix bracing, aluminum Space Frame construction, the Turbine Head and Solid Body Tweeter-on-Top work together to minimize cabinet resonance and mechanical interference.
Technology & Design
Diamond Dome & Solid Body Tweeter-on-Top — Bowers & Wilkins' Diamond dome tweeter is housed in a solid, elongated enclosure positioned independently above the main cabinet. This arrangement reduces interference from cabinet vibrations while minimizing diffraction around the high-frequency driver for cleaner imaging and greater openness.
Continuum Cone, Biomimetic Suspension & Turbine Head — The 6-inch Continuum Cone FST midrange is housed within the rigid Turbine Head and uses Bowers & Wilkins' Biomimetic Suspension in place of a conventional fabric spider. By reducing unwanted air pressure and mechanical noise behind the cone, the system is designed to reveal finer midrange detail.
Twin 10-Inch Aerofoil Bass Cones — The Aerofoil bass cones use a variable-thickness profile engineered to provide stiffness where it is most needed while maintaining low mass. Two 10-inch drivers give the 801 D5 the displacement required for effortless low-frequency dynamics and exceptional extension.
Matrix Cabinet & Aluminum Space Frame — Internal Matrix bracing reinforces the enclosure in multiple directions, while aluminum structural elements and the curved cabinet architecture further suppress resonance. The upgraded aluminum plinth provides a rigid foundation for the entire loudspeaker.
FAQ — Bowers & Wilkins 801 D5
Is the Bowers & Wilkins 801 D5 sold as a pair?
This listing is for one matched stereo pair of Bowers & Wilkins 801 D5 floorstanding loudspeakers.
How much amplifier power is recommended for the 801 D5?
Bowers & Wilkins recommends 50 to 1000 watts per channel into 8 ohms with unclipped program material. Because the speaker's impedance can fall to 3.0 ohms, a high-quality amplifier with strong current delivery is recommended for achieving its full performance potential.
How deep does the 801 D5 play?
Bowers & Wilkins specifies a frequency response of 15Hz to 28kHz ±3dB, with an overall -6dB frequency range of 13Hz to 35kHz. Its dual 10-inch Aerofoil bass drivers provide exceptionally deep low-frequency extension for a passive floorstanding loudspeaker.
Can the 801 D5 be used in a reference home theater?
Yes. The 801 D5 can anchor an exceptionally high-performance home theater as the front left and right loudspeakers. Bowers & Wilkins specifically identifies the HTM81 D5 center-channel speaker as a matching option for systems built around the 801 D5.
