CM9

This EISA award-winning floorstanding speaker will fill even the largest domestic spaces with music so richly detailed, and so startlingly lifelike, that it will leave you speechless.

CM9

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 CM9’s 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 speaker’s façade. For the finish, you can choose either one of two real-wood veneers in Rosenut or Wengé, or a highly polished gloss black.

EISA Loudspeaker Award 2009-2010
“This handsome floorstanding loudspeaker offers tremendous value for money, and features B&W’s highly regarded FST midrange unit as part of a four-driver system. The woven Kevlar cone of the FST driver is swaged at its edge and rests on a ring of foamed plastic that acts in compression. This novel arrangement improves the driver’s dissipation of unwanted vibrations but limits its excursion, so the unit hands over to twin 165mm bass drivers, reflex loaded through a dimpled port, for deep and extended low frequencies. The speaker offers a healthy sensitivity but is reasonably tough to drive – weedy amplifiers need not apply! Suitably partnered, the CM9 offers a very lush sound, big and expressive with a very realistic sense of musical dynamics. It’s one of B&W’s most compelling floorstanders to date and at a price that seals its EISA commendation.”
