Bowers & Wilkins HTM71 S3 - Center Channel Speaker
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.
Solid Body Tweeter
The 700 Series features the latest generation of Bowers & Wilkins' iconic Solid Body Tweeter-on-Top housing. Its new, more elongated form incorporates a longer tubeloading 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.
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.
Biomimetic Suspension
The new Biomimetic Suspension, first seen on the 800 Series Diamond, 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.
Decoupled Midrange Assembly
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.
Aerofoil™ Profile bass cone
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.
Curved Baffle
The new 700 Series features a curved front baffle for the first time. This allows the midrange and bass drivers to be located in individual pod-type housings that sit proud of the speaker baffle. When combined with the curvature of the structure, this new approach – derived from the 800 Series Diamond – reduces the audible impact of the cabinet, creating a cleaner, more open and more immersive sound.
