Bowers & Wilkins 704 S2 Floorstanding Speakers

704 S2 Floorstanding speaker

Looks can be deceiving. Despite its slim dimensions, 704 S2 has the commanding presence of a much larger speaker, thanks to advanced technologies such as a dedicated Continuum™ cone FST™ midrange.

Slim looks, big sound

With the 704, music is a revelation, with details picked out in pin-sharp detail and with exceptional realism.

Sharper detail

Carbon Dome tweeters are a brand new technology 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

Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone midrange driver.

Clean and clear

The midrange drivers in these floorstanders feature decoupled design, adapted from a similar system in the 800 Series Diamond. Decoupling reduces cabinet colouration, and boosts midrange clarity.

A triumph of science

Developed using advanced computer modeling techniques, the Aerofoil™ Profile bass cone has variable thickness, providing stiffness and rigidity where it’s needed most. The result: deep and dynamic bass.
