Bowers & Wilkins HTM81 D4 Centre Channel Speaker...

... arguably having the most important job in a home theatre speaker system, the HTM81 D4 has an enviable array of advanced technologies to reinforce the point, including Solid Body tweeter-on-top, a decoupled Continuum Cone midrange drive unit and twin 200mm (8in) Aerofoil bass cones mounted into Aluminium bass pods.

(Optional FS-HTM D4 stand sold separately)

Diamond Dome Tweeter...

One of our 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 we introduced it, we haven't found a better tweeter dome technology.Bowers & Wilkins - HTM81 D4 - Printable Information Sheet
