Its new, more elongated form incorporates a longer tube-loading system to produce an even more free and open sound with high frequencies. The carefully decoupled housing is milled from a single solid block of aluminum to better resist resonance. Sharper detail Carbon Dome tweeters are purpose-built for the 700 Series. Delivering a dramatic improvement on the aluminum double dome tweeter, they raise the breakup threshold to 47kHz, for pinpoint imaging accuracy and detail. Truly amazing sound Thanks to its composite construction, the Continuum™ cone avoids the abrupt transitions in behaviour that can impair the performance of a conventional drive unit. The result is a more open, neutral performance that delivers voices and instruments with precision and transparency. Clean and clear Every three-way loudspeaker in the new 700 Series has a dedicated midrange cone using four key Bowers & Wilkins technologies: the Continuum cone, FST™, Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker’s bass drivers. A triumph of science The Bowers & Wilkins HTM71 S3 Centre Speaker is developed using advanced computer modelling techniques, the Aerofoil™ Profile bass cone has variable thickness, providing stiffness and rigidity where it’s needed most. The result: deep and dynamic bass.
