B&W HTM71 S3 - Center Speaker
Bowers & Wilkins’ flagship centre speaker features a carbon dome drive unit housed in a Tweeter-On-Top enclosure, a 130mm (5”) Continuum Cone FST™ midrange driver – particularly important for dialogue clarity – and two Aerofoil™ Profile bass drivers. It’s the perfect partner for the 705 S3, 703 S3 and 702 S3.
Uncompromising vocal performance
The new HTM71 S3 features Tweeter-on-Top technology, ensuring perfect integration in a surround system with similarly equipped 700 Series models.
A home for high frequencies
The 700 Series adopts the latest generation of the Tweeter-on-Top Solid Body. The more elongated shape incorporates a new tweeter loading system that produces an even freer and more open sound at high frequencies. The carefully decoupled housing is milled from a single solid block of aluminum to better resist resonances.
Sharper details
Carbon dome tweeters have been specially developed for the 700 Series. They offer a marked improvement over aluminium double domes, raising break-up to 47kHz for precise, detailed imaging.
A truly amazing sound
Thanks to its composite structure, the Continuum™ cone avoids the abrupt behavior transitions that can compromise the performance of a conventional speaker. The result is a more open and neutral sound, which delivers vocals and instruments with precision and transparency.
Clean and clear
Each three-way speaker in the new 700 Series features 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 cabinet’s woofers.
A triumph of science
Developed using advanced computer modeling techniques, the Aerofoil™ Profile woofer features variable thickness, providing rigidity where it is needed most. The result: deep, dynamic bass.
