The tweeters atop Bowers & Wilkins 703 S3 loudspeakers are a house for high frequencies. The Solid Body Tweeter-on-Top housing is elongated, incorporating a longer tube-loading system to produce a free and open sound when reproducing high frequencies. The carefully decoupled housing is milled from a single aluminium block to resist resonance. To handle deep bass, Aerofoil Profile bass cones are made with variable thicknesses, providing stiffness and rigidity where it's needed most.

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.

A house for high frequencies

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 aluminium to better resist resonance.

Sharper detail

Carbon Dome tweeters are purpose-built for the 700 Series. Delivering a dramatic improvement on the aluminium 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

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.
