Bowers and Wilkins 683 S2
Brand Bowers & Wilkins
The largest speaker in the 600 Series. This floorstander is ideal for audiophile stereo and home theatre applications in larger rooms, delivering serious performance and amazing value.
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.
As well as new bass driver construction techniques and a new tweeter, brought in from Bower & Wilkins high-end series, the 683 S2 also boasts an FST Kevlar midrange driver. Serious technology, serious performance, but seriously affordable for a speaker of this calibre.
Tweeter diaphragms must be light and stiff, to reproduce high notes accurately. Bowers & Wilkins' Double Dome tweeters use a thin and light aluminium dome, surrounded by a thicker ring, to prevent audible distortion. 600 Series tweeters are further 'Decoupled' from the cabinets to reduce vibration.
