The 683 S2 features a Decoupled Double Dome tweeter – technology evolved from Bowers & Wilkins CM10 speaker. The double dome design uses an extremely thin aluminium dome for lightness, surrounded by a thicker aluminium ring for rigidity. The result is a far more precise treble performance. And while the tweeter looks like it?s part of the main speaker, it?s physically separated in its own gel-filled cavity, so performance isn?t hit by unwanted resonances or vibrations, for a more natural, spacious sound.
Serious and accurate bass performance is equally vital to such a room-filling speaker. That?s why the 683 S2 features a new bass driver construction method, using a similar method of bracing to the tweeter with twin layers of aluminium. The richer, distortion-free bass response is sumptuous.
