Bowers & Wilkins HTM71 S3 Signature Centre Speaker

The HTM71 S3 Signature arrives as a first-of-its-kind Signature centre channel speaker.

Designed predominantly for use in home theatres, the HTM71 S3 Signature delivers exceptional vocal realism to any movie-watching experience.

It features optimised technologies, such as our proprietary decoupled Continuum midrange drive unit and Tweeter-on-Top, plus upgraded bass motor systems, improved capacitors, revised speaker terminals, and a more open tweeter grille mesh, as developed for our 800 Series Signature loudspeakers.

 

 

Crafted. Honed. Perfected.

With the 700 Series, Studio Sound comes home.

 

700 Series Signature builds on that extraordinary pedigree, featuring floorstanding and stand-mount loudspeakers, plus a first-of-its-kind Signature centre channel speaker. The collection forms our most extensive Signature range yet. Optimised technologies and unique, luxurious finishes combine to deliver performance and elegance that’s a level above the best.

 

 

 

 

Upgraded crossovers

The new 700 Series Signature models use upgraded crossover designs crafted by our expert engineers. Developed using rigorous testing, Bowers & Wilkins’ engineers carefully optimise these crossovers to perfection, to maximise the loudspeakers’ performance. The 705 S3 Signature utilises an upgraded mid-bass motor system, improved capacitors and revised speaker terminals for even cleaner, refined sound.

 

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.

 

Signature Finishes

700 Series Signature looks as beautiful as it sounds. With the choice of two luxurious finishes, Midnight Blue Metallic paint or Datuk Gloss wood veneer, each model complements exceptional performance with elegant design.
