Design

The tweeter is a Nautilus™ tube-loaded aluminium dome, decoupled from the main baffle to cut down unwanted vibrations. The bass/midrange driver has a woven Kevlar® cone, chosen for rigidity and low distortion. The cabinet is heavily braced. Flowport™ technology is there to minimize port noise and improve bass response.

Context

The CM1 sits in the CM Series, the entry-level line in the Bowers & Wilkins range, below the flagship 800 Series. It was designed to bring core Bowers & Wilkins technologies, such as Kevlar® cones and Nautilus™-derived tweeters, into a more accessible product tier.
