Description
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 its part of the main speaker, its physically separated in its own gel-filled cavity, so performance isnt 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. Thats 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.Specifications:- Technical features: Decoupled Double Dome aluminium tweeter with Nautilus tube loading- Kevlar brand fibre cone FST midrange driver- Dual-layer aluminium cone bass driver Flowport- Description: 3-way vented-box system- Drive units 1x *25mm (1 in) aluminium dome high-frequency- 1x *150mm (6 in) woven Kevlar cone FST midrange 2x *165mm (6.5 in) aluminium cone bass- Frequency range -6dB at 30Hz and 50kHz- Frequency response 52Hz - 22kHz 3dB on reference axis- Dispersion Within 2dB of reference response Horizontal: over 60 arc Vertical: over 10 arc- Sensitivity 89dB spl (2.83V, 1m)- Harmonic distortion 2nd and 3rd harmonics (90dB, 1m)
