The Bowers & Wilkins HTM71 S3 has undergone a major upgrade over the previous S2 version with improved aesthetics and a massive step up in sonic performance. B&W’s 700 S3 flagship centre-channel speaker features a Carbon Dome drive unit housed in a Tweeter-On-Top enclosure, a 130mm (5in) Continuum Cone FST™ midrange driver – particularly important for clarity with dialogue – and twin Aerofoil™ Profile bass cones. It’s the perfect partner for the 705 S3, 703 S3 and 702 S3.
