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.
The all-aluminium 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.
Innovation is at the heart of everything B&W does. They question, they examine, they understand and then they evolve. They use computer modelling to explore and reimagine every aspect of loudspeaker design.
801 D4 is the flagship and the most powerful model in the new 800 Series Diamond range. Its no-compromise design includes all our most advanced technologies in their purest, most optimised form alongside crossover components of the highest quality. You want a reference loudspeaker? This is it…
