ℹ Product Information
Bowers & Wilkins was founded in Worthing, England in 1966 by John Bowers, a man who believed that the purpose of a loudspeaker was simply to reproduce recorded music as faithfully as possible, and that achieving this required investment in research rather than compromise in manufacturing. That belief produced, over subsequent decades, a series of loudspeaker innovations — the first practical diamond tweeter, the decoupled tweeter housing, the matrix-braced cabinet — that have become reference technologies in the industry. The 800 Series, introduced in the 1970s and continuously refined since, is the direct expression of that research: the speaker that Abbey Road Studios and countless other world-class recording facilities trust to hear what they are actually recording.
ENGINEERING PHILOSOPHY
The 800 Series Diamond range incorporates technologies developed without regard to cost: a tweeter dome machined from pure diamond, chosen because its extreme stiffness pushes resonance far beyond the audible range; a Continuum midrange cone developed over years of materials research to eliminate the 'cone cry' coloration present in all conventional cone materials; and a Biomimetic Suspension system that reduces non-linear distortion at low frequencies. The turbine head tweeter enclosure decouples the tweeter from the cabinet entirely, so that cabinet vibration — however small — cannot influence the treble reproduction. These are not marketing descriptions. They are engineering solutions to problems that affect every loudspeaker, implemented at a level of investment that only a company of B&W;'s scale can sustain.
WHY THE AUDIO TAILOR CARRIES BOWERS & WILKINS 800 SERIES
We carry Bowers & Wilkins 800 Series because it represents one of the most rigorously developed and extensively validated loudspeaker designs in the world. It is the benchmark against which every other speaker in our range is assessed — and it earns that position every time.
Celebrating 40 Years of Excellence: The 801 D4 Loudspeaker
Innovation Redefined: 801 D4 Loudspeakers
For four decades, the 801 series has epitomized cutting-edge loudspeaker technology. The 801 D4, the latest incarnation, showcases our newest advancements and most original thinking, solidifying its status as an iconic loudspeaker.
Unmatched Precision: The Ultimate Matrix™ Bracing
The 801 D4 features our most advanced Matrix™ bracing system yet. With interlocking panels that reinforce the cabinet walls internally, this sophisticated aluminum bracing minimizes resonance, delivering a remarkably authentic soundstage.
Revolutionary Design: The Turbine™ Head
Our all-aluminum Turbine™ Head encases the Continuum midrange cone in a rigid, critically damped enclosure, eliminating unwanted resonances. Decoupled from both the bass enclosure and the tweeter body, it achieves unparalleled midrange clarity.
Breakthrough Performance: Biomimetic Suspension
Innovation thrives on unconventional thinking. The new Biomimetic Suspension in the 801 D4 transforms midrange performance by drastically reducing unwanted air pressure and coloration from traditional fabric spiders, resulting in stunning midrange transparency.
The Science of Sound: The 801 D4
Innovation is the heartbeat of our design process. Through rigorous questioning, examination, and understanding, we evolve our loudspeakers using advanced computer modeling to reimagine every design aspect. Discover the technologies that make the 800 Series Diamond exceptional.
Flagship Excellence: The State of Our Art
The 801 D4 stands as the pinnacle of the new 800 Series Diamond range, embodying a no-compromise design philosophy. Integrating our most advanced technologies and premium crossover components, the 801 D4 sets a new standard for reference-quality loudspeakers, destined to be the benchmark for years to come.
