702 S3's Carbon Dome tweeter is housed in an all-new Solid Body Tweeter assembly. At the same time, with its new downward-firing port configuration and a trio of Aerofoil Profile bass cones, it delivers bass that’s both profoundly deep and endlessly articulate. Our flagship, the 702 S3, is a state-of-the-art tower speaker that defines new standards for performance in its class. If you want the best, this is it. 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.
