Description HTM81 D4 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. Features include the iconic Solid Body tweeter-on-top, a decoupled Continuum™ Cone midrange drive unit and twin 200 mm (8-inch) Aerofoil™ bass cones. The Aerofoil bass cone technology remains an outstanding solution to the conundrum of combining low mass and high stiffness in bass cones. All thanks to its carbon-fibre skin and variable-profile foam core. Now, B&W have added the foam Anti-Resonance Plug for lower distortion and even cleaner bass. One of the 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 B&W introduced it, they haven’t found a better tweeter dome technology. 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. Features 3-way vented-box system. Diamond tweeter.
