Bowers & Wilkins 702 S3

The Bowers & Wilkins 702 S3 redefines what a floorstanding loudspeaker can achieve at this level — a three-way design of extraordinary refinement that sets a new standard for transparency, imaging, and dynamic authority. Drawing on technologies developed for the flagship 800 Series Diamond, the 702 S3 brings a level of engineering rigour to the 700 Series that transforms your listening experience entirely. This is a speaker built without compromise: every driver, every cabinet surface, every crossover component exists to serve a single purpose — the honest, uncoloured reproduction of music at the highest level.

Solid Body Tweeter-on-Top

The 702 S3's Carbon Dome tweeter is housed in an all-new Solid Body Tweeter assembly — milled from a single solid block of aluminium to resist resonance at a molecular level. Its elongated form incorporates a longer tube-loading system, producing a sound that is more free, more open, and more extended than any previous 700 Series design. The carefully decoupled housing ensures that vibration from the main cabinet never reaches the tweeter, preserving the integrity of high-frequency reproduction with a precision previously unsurpassed in this class.

Carbon Dome Tweeter

Purpose-built for the 700 Series, the Carbon Dome tweeter raises the breakup threshold to 47kHz — far beyond the limits of human hearing, but critical for the phase and timing accuracy that delivers pinpoint imaging. Where conventional aluminium dome tweeters colour the upper frequencies with their own resonant signature, the Carbon Dome remains perfectly composed, revealing micro-detail and spatial information with effortless realism.

Continuum™ Cone Midrange

The 702 S3's dedicated midrange driver combines four of Bowers & Wilkins' most advanced technologies: the Continuum™ cone, FST™ (Fixed Suspension Transducer), Biomimetic Suspension, and midrange decoupling. The Continuum™ cone's composite construction avoids the abrupt transitions in behaviour that impair conventional drive units, delivering voices and instruments with a neutrality and transparency that reveals the full emotional weight of the performance. Midrange decoupling ensures that bass driver operation never reaches the midrange unit — the result is a purity of reproduction at levels you have not heard before.

Aerofoil™ Profile Bass

Developed using advanced computer modelling, the Aerofoil™ Profile bass cone features variable thickness — providing stiffness and rigidity precisely where the physics demand it. Three of these cones, combined with a new downward-firing port configuration, produce bass that is both profoundly deep and endlessly articulate. Timing is locked, transients are precise, and the low-frequency foundation of the music is rendered with a sense of control and authority that defines the 702 S3's character.

Who Is It For?

The Bowers & Wilkins 702 S3 is built for the serious listener who demands a full-range floorstanding speaker capable of filling a large room with effortless authority. If your system is built around a high-quality amplifier and source, the 702 S3 will reveal everything it is capable of — and reward your investment with a performance that scales to the finest recordings in your collection. It pairs naturally with a subwoofer from the Bowers & Wilkins DB Series — the DB3D or DB1D extend the low-frequency foundation still further for those who want the complete picture.
