If itʼs hard to put the sound of the CM9 into words, thatʼs just as well. This top-of-the-range floorstanding speaker will fill even the largest domestic spaces with music so richly detailed, and so startlingly lifelike, that it will leave you speechless.
The three-way CM9 delivers truly commanding bass with the aid of twin 165mm paper/Kevlar® cone drive units. An FST® driver, with its characteristic compression surround supporting the outer edge of the distinctive Kevlar® cone, is specially developed for outstanding midrange performance. The CM9ʼs Nautilus™ tube-loaded aluminium dome tweeter keeps high frequencies crisp and sharp all the way up to 50kHz and beyond.
The quality of CM Series drive units has made it possible to use minimalist crossovers throughout the whole range. The resulting gentle transition between drivers avoids the unnaturally rapid changes in dispersion that bedevil more complex designs, while the high quality components, carefully chosen after exhaustive listening tests, ensure that as little as possible gets between you and the sound of the original recording.
All CM Series speakers come with aluminium driver trims. Grilles attach magnetically, so there are no unsightly grille-mounting features to spoil the clean lines of the speakerʼs façade. For the finish, you can choose either one of two real-wood veneers in Rosenut or Wengé, or a highly polished gloss black.

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.
