B & W HTM81 D4 Black Central Speaker
Acoustic box for the central channel.
The largest of our acoustic boxes for the central channel is designed to be combined with 801 D4 and 802 D4. Extremely powerful, it possesses both the sense of scale and extension in means to pair perfectly with the quality offered by its illustrious.

In the center of everything
It can be affirmed that the central acoustic box is the most important of a home theater system, and the HTM81 D4 has an enviable combined of advanced technologies - among them a tweeter with massive enclosure mounted in the upper area, a speaker Media with CONO Continuum ™ and two bass speakers with 200 mm Aerofoil ™ cone (8 inches) - to reinforce this assertion.
Cone of serious airfoil
Our Aerofoil technology for bass cones continues to be an exceptional solution to the puzzle of combining low mass and high rigidity in them thanks to its external carbon fiber coating and its variable thickness foam core. Now, we have added the Foam Anti-Resonance Makers to reduce the vibration and get some even cleaner bass.
Dome Tweeter Diamond
Undoubtedly one of our most significant achievements of the last two decades, the ultralight and sovereignly precise Domo Diamond Tweeter is the perfect combination of low mass, exceptional rigidity and outstanding definition. 15 years after having introduced him into the market, we still did not find a better dome tweeter technology.
Aluminum pods in woofers
HTM81 D4 rides two airfoot cones in dedicated solid aluminum pods, each of which is fixed to an aluminum plate which in turn is fixed to the most rigid part of its curved enclosure. Forming a single metallic piece, these extremely rigid structures provide the perfect mechanical location for the aforementioned bass cones.
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 combine to make the 800 Diamond ™ series so special here.
