The loudspeaker that sets the standard other high-end designs will be judged by for years to come. Endowed with every new technology the 800 Series Diamond has to offer, the reference-quality 801 D4 is an instant icon. 801 D4 is defined by it. In each of its incarnations over the decades, 801 has always been the most advanced loudspeaker that Bowers & Wilkins know to make at that particular point in time, a showcase of all Bowers & Wilkins newest technologies and most original thinking. Small wonder it has become an icon. The ultimate Matrix. Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. The Matrix assembly in 801 D4 is Bowers & Wilkins best yet, upgraded with extensive aluminium bracing to reinforce key stress points. The all-aluminium Turbine Head houses Bowers & Wilkins Continuum midrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances. At the same time, it’s decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet. Biomimetic Suspension. Sometimes, making a big difference takes unconventional thinking. Bowers & Wilkins new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and coloration that a traditional fabric spider can generate. The result? Midrange transparency you wouldn’t believe. The science of sound. Innovation is at the heart of everything Bowers & Wilkins do. They question, they examine, they understand and then evolve. Bowers & Wilkins use computer modelling to explore and reimagine every aspect of loudspeaker design. Bowers & Wilkins 801 D4 Floorstanding Speakers - is an icon reborn.
