684 S2 Kule Hoparlör
Room-filling sound without a room-filling speaker cabinet. Slimmer than ever before, the 684 S2 offers an amazing combination of floorstander power, audio performance and unbeatable value.
Switching to 5-inch bass/midrange drivers from the previous
6.5-inch cones, means the 684 S2 is now significantly slimmer than its
predecessor, with simultaneously improved audio performance, thanks to Bowers
& Wilkins innovation. The two Kevlar cone drivers benefit from smaller
voice coils to increase sensitivity.
The 5-inch drivers now also feature Anti-Resonance Plug dustcaps, technology
taken from our high-end PM1 speakers, that improve pistonic movement inside the
voice coil. This helps to deliver amazingly distortion-free midrange
performance, all in a smaller space.
As well as slimmer, improved driver performance, the 684 S2 also features a
Decoupled Double Dome tweeter. Double dome technology, brought across from the
CM10, increases tweeter rigidity for a more precise sound, while the tweeter
sits in a gel-filled cavity, decoupled from the surrounding cabinet - which
removes resonances and vibrations, for a more natural, spacious sound.
