Elegance and performance defines the 706 S3.  Technology from the flag ship 800 Series Diamond enables this range of speakers. Consequently, with eight models to choose from, there’s a speaker to suit every home. Inspired by recording studios, made for living rooms: with the Bowers & Wilkins 700 Series, studio sound comes home.

The powerful 706 S3 is the ideal stand mount loudspeaker for delivering exceptional sound in larger spaces.

Thanks to 706 S3’s decoupled Carbon Dome tweeter and carefully upgraded crossover, it provides exceptional detail and insight into your music, while its large 165mm (6.5in) Continuum Cone bass/midrange drive unit provides ample scale and extension for use in larger spaces.

Sharper Detail

For the 700 Series we built special Carbon Dome tweeters. To sum up, it delivers a dramatic improvement on the aluminum 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 behavior that can impair the performance of a conventional drive unit. As a result a more open, neutral performance that delivers voices and instruments with precision and transparency.

Inspired by Greatness

Consequently, the new curved cabinet baffle and individual drive unit pods are inspired by the 800 Series Diamond, and greatly reduce cabinet coloration, giving a cleaner, more immersive sound.
