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.
