This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is our benchmark, our icon; the most advanced range of loudspeakers we know how to make. For us, the 800 Series Diamond is everything we know, and everything we are.
Bowers & Wilkins HTM81 D4 Centrinė kolonėlė
The HTM81 D4, our largest centre-channel model adopts the Biomimetic Suspension system and 6in (150mm) FST midrange cone used in 802 D4 and 801 D4. To ensure perfect optimisation with 801 D4, it also includes the silver-topped pole piece found in that model’s midrange motor system. Finally, it adds an internal aluminium midrange enclosure to provide a perfect mechanical location for that cone to operate.

Excellence. Evolved.
HTM81 D4
Our largest centre-channel speaker is designed to be the perfect partner for the 801 D4 or 802 D4. Small wonder, then, that it's such a powerful performer, with sound that perfectly matches the quality of its illustrious stablemates.


Midrange enclosure
Inside HTM81 D4, we use a stiff, aluminium enclosure designed to maximise the performance of the midrange drive unit. lt provides a controlled location point for the midrange decoupling and prevents unwanted air leakage into the surrounding cabinet.
Aerofoil bass cone
Our Aerofoil bass cone technology remains an outstanding solution to the conundrum of combining low mass and high stiffness, thanks to its carbon-fibre skin and variable-profile foam core. Now, we have added the foam Anti-Resonance Plug™ for lower distortion and even cleaner bass.
