The largest centre-channel speaker in the range 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 centre of it all
The centre-channel speaker is arguably the most important in home theatre – 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 (8in) Aerofoil™ bass cones.
Aerofoil bass cone
The 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-fibre skin and variable-profile foam core. Now, B&W added the foam Anti-Resonance Plug for lower distortion and even cleaner bass.
Diamond dome tweeter
One of the most significant B&W 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.
Aluminium bass pods
HTM81 D4 mounts two Aerofoil bass cones in twin solid aluminium bass pods, each of which is clamped into an aluminium 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.

B&W provides solutions for any demand and application – be it the stage direction studio of a philharmonic venue or the acoustic supply of a home cinema. Tranquil and mature sound meet excellent workmanship.
We have a wide range of B&W speakres available for demonstration in our HiFi studios in Berlin-Kreuzberg. We look forward to your visit!
