Bowers & Wilkins HTM81 D4 Centre Speaker

HTM81 D4 centre channel speaker

Bowers & Wilkins largest centre-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 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

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-fibre 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 Bowers & Wilkins 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 they introduced it, they haven’t found a better tweeter dome technology.

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.

The science of sound

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

800 Series Diamond™

Excellence. Evolved.


An icon reborn

This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is the benchmark, the icon; the most advanced range of loudspeakers Bowers & Wilkins know how to make. For Bowers & Wilkins, the 800 Series Diamond is everything they know, and everything they are.

Decades in the making

John Bowers wanted the original Model 801 to clearly be superior to anything he had done before: to be the best loudspeaker the world had ever heard. Over the decades that have followed, Bowers & Wilkins constantly evolved his original design, but his passion for perfection continues to inspire Bowers & Wilkins to this day.

A legacy like no other

Other speakers merely replay recorded music. 800 Series Diamond makes it. The speaker of choice for recording industry professionals for decades, it has helped artists and studios the world over to create the music and film soundtracks that have shaped a generation.

Form meets function

Bowers & Wilkins design always has a purpose. Decades of cutting-edge research into loudspeaker design have given us a deep understanding of how to make them sound wonderful. And if that same knowledge also inspires beautiful forms wrapped in a range of four luxurious finishes, who’s complaining?
