If it’s hard to put the sound of the CM9 into words, that’s 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 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.
