Bowers & Wilkins HTM71 S3 Centre Speaker

Our flagship centre-channel loudspeaker in the 700 Series, the HTM71 S3 features a Carbon Dome drive unit housed in a Tweeter-On-Top enclosure, making it the perfect match for its 705 S3, 703 S3 and 702 S3 stablemates.

This approach allows for outstanding integration and an even more immersive listening experience across our premium 700 Series-based surround sound systems.

The HTM71 S3 also features an all-new 130mm (5in) Continuum Cone FST midrange driver complete with our Biomimetic Suspension – particularly important for clarity with dialogue.

 

 

Studio Sound Comes Home

The new Bowers & Wilkins 700 Series is defined by elegance and driven by best-in-class performance. Every model in our most extensive range is inspired by the recording studio and enabled by cutting-edge technologies first developed for our flagship 800 Series Diamond.

 

The 700 Series contains eight models: there’s a speaker to suit every home and every requirement, whether your passion is high-performance stereo, immersive home cinema or a mix of both.

 

 

Bring Hollywood Home

With two centre channel speakers to choose from plus the option of matching subwoofers, in-wall and in-ceiling speakers, the new 700 Series performs brilliantly in any home cinema set-up.

 

 

 

 

Carbon Dome tweeters

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.

 

Solid Body Tweeter-on-Top

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.

 

Biomimetic Suspension

Sometimes, making a big difference takes unconventional thinking. The transition from our famous yellow Aramid Fibre midrange cones to our Continuum cone technology resulted in a massive improvement to midrange performance. Now, we’ve turned our attention to another crucial element in a loudspeaker cone: the fabric spider.

 

The new Biomimetic Suspension revolutionises midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible.

 

Continuum cone

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.

 

Aerofoil Profile bass cone

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.
