804 D4

Floor-standing speaker

804 D4 Black

For listeners who crave the performance of an 800 Series Diamond™ floorstander but prefer a more conventional aesthetic, the 804 D4 is the perfect choice.

Its new cabinet and plinth make it their best-performing 804 yet.

Classic quality

804 D4 Wa;nut

804 D4 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

Aluminium top-plate

Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminium 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.

Aluminium plinth

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.

Get a Head

804 D4 is the entry-level floor standing model in the 800 Series Diamond range.

Step up to 803 D4 and you’ll find larger bass drivers (180mm, 7in) plus, crucially, the addition of a Turbine™ Head enclosure for the 130mm (5in) midrange cone, which adds even more spaciousness to the sound.

Bowers & Wilkins

1960s: Humble beginnings

The sleepy coastal town of Worthing in South England might not look like a hotbed of 1960s freewheeling experimentation, but for audio fans it’s a place that’s synonymous with innovation. Thanks to the first Bowers & Wilkins speakers built here in the early years of the company, music lovers could experience albums such as Sgt. Pepper and Pet Sounds in new, mind-expanding depth and clarity

1966: Beginings

John Bowers begins assembling speaker systems in the workshop of his electronics shop in Worthing, South East England Following an inheritance of £10,000 from a satisfied customer, John Bowers sets up his own loudspeaker company

1966: P1

The first Bowers & Wilkins loudspeaker. The profit from P1 allowed the company to invest in new calibration equipment

1968: Domestic Monitors

The DM1 and DM3 were launched to bring high quality audio to more customers, at an affordable price point

1970s: A decade of milestones

With the company established and growing fast, Bowers & Wilkins developed its reputation for innovative design backed up by world-leading R&D. They introduced new forms and design concepts including Tweeter-on-Top, new cone materials such as Aramid fibre, and it all culminated in the launch of the iconic 801, soon to become the reference speaker of choice for many of the world’s leading recording studios

1970: DM70

With its curved cabinet, the DM70 changed the shape of loudspeaker design

1980s: The application of science

Extensive investment in research led to the establishment of the company’s dedicated R&D facility in Steyning. The era of MTV pop superstardom and bombastic stadium rock also saw Bowers & Wilkins buck the trend and introduce something small and unobtrusive: the “compact monitor”, or CM1

1990s: Rewriting the rulebook

The 1990s saw the pioneering work of the Steyning research team realised in spectacular fashion with the launch of Nautilus™, a speaker that rewrote preconceived notions of speaker design. It also saw major product launches at both ends of the spectrum, with the unveiling of the highly regarded entry-level 600 Series and the flagship Nautilus 800 Series

2000s: Expansion in to new categories

The decade that brought us iPods and smartphones saw them embrace the new world with the launch of the iconic Zeppelin. They also expanded into the car audio category and transformed the performance of their 800 Series with the development of the Diamond-dome tweeter

2015: 800 Series Diamond

The latest version of their flagship introduced a complete redesign and revolutionary new technologies, such as the Continuum™ cone
