Bowers & Wilkins 704 S3

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.
