Bowers & Wilkins 600 Series Decoupled dual-layer 1" speaker 685 S2

Model #:685 S2

Bowers & Wilkins At home on a stand, wall or bookshelf, the versatile 685 S2 is ideal for stereo and home theatre uses in most rooms. And performance is enhanced with the addition of a Decoupled Double Dome tweeter.

The Decoupled Double Dome tweeter found in the 685 S2, and the rest of the new 600 Series, is technology taken straight from our award-winning CM10 speaker. A dual-layer design combines a thin aluminium dome for lightness and a thicker aluminium ring for rigidity the result is absolutely stunning, with far greater clarity in the audible spectrum.

The tweeter is also decoupled from the main cabinet, kept physically separate in its own cavity with a ring of gel cushioning it from vibrations. This improves imaging and dispersion for a more natural, spacious treble.

As well as a decoupled, double dome aluminium tweeter, the two-way 685 S2 features a full-range 6.5-inch driver constructed from woven Kevlar and using Anti-Resonance Plug dustcaps, as seen in high-end Bowers & Wilkins speakers. The result is stunning audio quality from a highly versatile smaller speaker.
