The new 703 S3 now features our iconic Tweeter-on-Top configuration for the first time, alongside a decoupled FST™ Continuum cone midrange driver – enhanced by the addition of our revolutionary new Biomimetic Suspension – and twin Aerofoil Profile bass drivers. The 700 Series features the latest generation of our iconic Solid Body Tweeter-on-Top housing. 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 resist resonance better. 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. Thanks to its composite construction, the Continuum™ cone avoids the abrupt transitions in behavior 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. 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. Developed using advanced computer modeling techniques, the Aerofoil™ Profile bass cone has a variable thickness, providing stiffness and rigidity where it’s needed most—the result: deep and dynamic bass.
