The Bowers & Wilkins HTM71 S3 is the ultimate Centre Speaker, the flagship centre speaker features a Tweeter on top with a Carbon Dome drive, it is designed to be the perfect partner for the new Bowers & Wilkins 705 S3, 703 S3 and 702 S3 speakers within a premium home cinema setup. With a 130mm (5in) Continuum Cone FST™ midrange driver – particularly important for clarity with dialogue – and twin Aerofoil™ Profile bass cones. 

Uncompromising vocal performance

The HTM71 S3 now features Tweeter-on-Top technology, ensuring perfect integration with similarly equipped 700 Series models in a surround sound system.

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.
