The 804D4 is the perfect choice for listeners who prefer a more conventional aesthetic but crave the performance of an 800 Series Diamond loudspeaker. Its new reverse-wrap cabinet follows the proven design principles established by its larger siblings.
The 804D4 is the entry-level floor-standing model in the latest 800D4 series: each new generation of 800 Series Diamond™ is heralded as a landmark event for Bowers & Wilkins. This is their benchmark, their icon; the most advanced range of loudspeakers they know how to make. For Bowers & Wilkins, the 800 Series Diamond is everything they know, and everything they are.
Other loudspeakers merely replay recorded music. 800 Series Diamond makes it. The monitor speaker of choice for recording industry professionals for decades, it has helped artists, composers and studios the world over to create the music and film soundtracks that have shaped a generation.
Bowers & Wilkins’ design always has a purpose. Decades of advanced research into the acoustic and mechanical fundamentals of loudspeaker cabinets have endowed them with a deep understanding of how to make them sound wonderful. And if that same knowledge also inspires beautiful forms, who’s complaining?
The full 800D4 series is available for demonstration in our industry-leading facilities with part exchange being welcome.
Excellence. Evolved.
804D4
Bowers & Wilkins’ 804D4 is perhaps more conventional in appearance than other floor-standers 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.
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.
A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminium plinth complete with a steel constrained layer damping sheet, which controls unwanted resonance. It also has greatly upgraded spikes for maximum stability and durability.
