Bowers & Wilkins 804 D4
For listeners who crave the performance of an 800 Series Diamond tower speaker but prefer a more conventional aesthetic, the 804 D4 is the perfect choice. Its new cabinet and plinth make it our best-performing 804 yet.
Bowers & Wilkins 804 D4 Floor Standing Speaker
- Diamond Dome Tweeter: Delivers exceptional high-frequency clarity and detail, thanks to its ultra-stiff and lightweight construction.
- Solid Body Tweeter-on-Top: An elongated, decoupled aluminum housing that minimizes resonance and enhances openness in the treble range.
- Continuum™ Cone FST Midrange Driver: A 130mm (5-inch) driver offering transparent and natural midrange performance.
- Aerofoil™ Cone Bass Units: Two 165mm (6.5-inch) woofers with variable thickness carbon-fiber skins for deep, controlled bass.
- Reverse-Wrap Cabinet Design: Constructed from a single piece of birch ply with an aluminum spine, enhancing structural rigidity and reducing resonance.
- Aluminum Plinth with Downward-Firing Flowport™: Provides a solid foundation and optimizes bass response by reducing turbulence.
- Matrix™ Bracing: An internal lattice structure that reinforces the cabinet, minimizing vibrations and coloration.
- Biomimetic Suspension: Replaces the traditional fabric spider with a composite system, reducing air pressure and coloration for improved midrange clarity
- Anti-Resonance Plug: Enhances bass performance by stabilizing the voice coil and reducing distortion.
- Premium Finishes with Leather by Connolly: Available in Gloss Black, Satin Rosenut, Satin Walnut, and White, each featuring luxurious leather trim on the top plate.

Classic quality
804 D4 is perhaps more conventional in appearance than other tower speakers in the 800 Series Diamond range, but it’s every bit as sophisticated. Its new Reverse-Wrap cabinet is both a mechanical and acoustic revolution in its class, and its new plinth ensures rock-solid, accurate bass response too.
Aluminum top-plate
Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminum top-plate. This also provides a perfect mounting point for all-new Leather by Connolly trim, with luxurious black leather for dark cabinets and light grey for lighter finishes.
Reverse Wrap cabinet
Instead of a conventional loudspeaker box, the cabinet in 804 D4 is made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.
Aluminum plinth
A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminum plinth complete with a steel constrained layer damping sheet, which controls unwanted resonance. It also has greatly upgraded spikes for maximum stability and durability.
The science of sound
Innovation is at the heart of everything we do. We question, we examine, we understand and then we evolve. We use computer modelling to explore and reimagine every aspect of loudspeaker design. Learn more about all the technologies that combine to make 800 Series Diamond so special here.
