Bowers & Wilkins HTM81 D4

Our 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 perfectly matches the quality of its illustrious stablemates.

Inside HTM81 D4, B&W uses a stiff, aluminum enclosure designed to maximise 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.

B&W 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, we have added the foam Anti-Resonance PIug for lower distortion and even cleaner bass.

The B&W HTM81 D4 will be on demonstration at Martins HI-Fi and we will also be hosting a future event. If you wish to book a private demonstration please contact us via the chatbox, call 01603 627010 or email
