Excellence. Evolved.

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

Bowers & Wilkins's largest center-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 a sound that matches the quality of its illustrious stablemates.

Midrange Enclosure

Inside HTM81 D4, a stiff, aluminum enclosure is designed to maximize the performance of the midrange drive unit. It provides a controlled location point for the midrange decoupling and prevents unwanted air leakage into the surrounding cabinet.

Aerofoil Bass Cone

The Aerofoil bass cone technology remains an outstanding solution to the conundrum of combining low mass and high stiffness, thanks to its carbon-fiber skin and variable-profile foam core. Now, an Anti-Resonance Plug™ has been added for lower distortion and even cleaner bass.
