Bowers and Wilkins 800 D4 Series Review

40 years of excellence

Innovation. 801 D4 is defined by it. In each of its incarnations over the decades, 801 has always been the most advanced loudspeaker that we know to make at that particular point in time, a showcase of all our 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 our best yet, upgraded with extensive aluminum bracing to reinforce key stress points.

Turbine™ Head

The all-aluminum Turbine Head houses our 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. Our new Biomimetic Suspension revolutionizes 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 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.
