B & W 801 D4 Walnut

40 years of excellence.

Innovation. The 801 D4 is defined by it. In each of its incarnations over decades, the 801 has always been the most advanced acoustic box that we have been able to do at that particular moment, a showcase of our most advanced technologies and our most original thinking. A small wonder that has become an icon.

Matrix ™ at its maximum expression.

The Matrix structure uses interconnected panels to internally reinforce the walls of the acoustic box in all directions, reducing resonances and creating a more credible sound scene. The Matrix structure used in 801 D4 is the best we have ever developed, improved with aluminum elements to reinforce critical fatigue points.

Turbine ™ head -

Built entirely in aluminum, the turbine head hosts our continuum ™ media cone in a rigid and critically damped enclosure to eliminate unwanted resonances. At the same time, it is uncoupled from the bass enclosure and the tweeter's body. The result? The most natural means never heard.

Biomimmic suspension.

Sometimes, marking the real difference leads to unconventional thinking. Our new biomimetic suspension revolutionizes the performance of the medium zone substantially reducing the unwanted air pressure and coloration that can generate an internal suspension -pider-conventional fabric. The result? A transparency in the media you could never imagine.

The science of sound.

Innovation is in the heart of everything we do. We question, examine, understand and then evolve. We use computer modeling to explore and reimaginate every aspect of the design of acoustic boxes. Learn more about all the technologies that are combined to make the 800 Diamond series so special here.

Our reference.

The 801 D4 is our flagship, as well as the most powerful model of the new 800 Diamond series. Its design without commitment includes all of our most advanced technologies in its purest and optimized form next to a frequency dividing filter executed with components of the highest quality.
