HTM81 D4

B&w’s largest center-channel speaker is designed to partner the 801 D4 and 802 D4. A powerful performer, it has both the scale and the midrange extension to perfectly match the quality of its illustrious stablemates.

At the center of it all

The center-channel speaker is arguably the most important in home theater – and the HTM81 D4 has an enviable array of advanced technologies to reinforce that point, including Solid Body tweeter-on-top, a decoupled Continuum™ Cone midrange drive unit and twin 200mm (8-in) Aerofoil™ bass cones.

Aerofoil bass cone

Bowers & Wilkins Aerofoil bass cone technology remains an outstanding solution to the conundrum of combining low mass and high stiffness in bass cones, thanks to its carbon-fiber skin and variable-profile foam core. Now, they have added the foam Anti-Resonance Plug for lower distortion and even cleaner bass.

Diamond dome tweeter

One of B&w’s most significant accomplishments over the past two decades, the ultra-stiff, supremely accurate Diamond dome tweeter is the perfect combination of low mass, exceptional stiffness and outstanding accuracy. 15 years after B&w introduced it, we haven’t found a better tweeter dome technology.

Aluminum bass pods

HTM81 D4 mounts two Aerofoil bass cones in twin solid aluminum bass pods, each of which is clamped into an aluminum plate fixed to the stiffest part of its curved cabinet. Formed as single pieces of metal, these stiff structures provide the perfect mechanical location for those powerful bass cones.

The science of sound

Innovation is at the heart of everything B&w do. They question, examine, understand and then evolve. Bowers & Wilkins use computer modelling to explore and reimagine every aspect of loudspeaker design.
