CM1

The CM1 may be ideal for smaller spaces, but don’t let the size of this bookshelf speaker fool you. Thanks to the quality of its construction, it’s capable of producing a sound that’s a match for its bigger brothers.

CM1

The partnership of a 130mm Kevlar® cone bass/midrange driver with a Nautilus™ tube-loaded aluminium dome tweeter helps the CM1 handle musical detail with ease across the full frequency spectrum. Despite the size of the speaker, the CM1’s bass is always deep and under control thanks to the CM Series’ magnet and voice coil system technology, which keeps distortion to a minimum.

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 facade. For the finish, you can choose either one of two real-wood veneers in Rosenut or Wengé or highly polished Gloss Black.

Sound & Vision June 2007
"With its cool, sophisticated looks and subtle performance, particularly in the all-important midrange, this is the type of system whose capabilities you'll really learn to love."

Soundstage June 2007
The Bowers & Wilkins CM1s are attractively styled minimonitors that will provide a rewarding listening experience. Their tweeter is the best that I have heard in the under-$1000 price range, approaching the performance of tweeters in much higher-priced speakers and validating the trickle-down claims of B&W.
