Product Summary
The magnetically shielded CMC centre speaker opens up the whole world of home
entertainment. It is available in two real wood veneers, Maple and Rosenut and the
brushed aluminium baffle emphasises the clean, modern design approach.
Tube loading the tweeter ensures far greater absorption of unwanted radiation from the rear of
the diaphragm. The resulting effect is to create a more focused and natural high frequency
sound. Flowport is integrally moulded with the terminal tray at the rear of the cabinet, its surface
is dimpled like a golf ball to smooth the airflow and reduce turbulence. Magnetic shielding
allows the speaker to be used close to a TV. Timbre-matching the CMC to the other CM Series
speakers ensures seamless integration of sound in a home theatre.
Technical highlights
Nautilus™ Tweeter: B&W's Nautilus™ Tweeter technology ensures that the
sound remains focused and time-sensitive and that the stereo-image is presented
with unparalleled three dimensional accuracy.
Kevlar®: B&W developed and patented the method of using Kevlar® for
loudspeaker cones to reduce unwanted standing waves. DuPont originally
created Kevlar® for use in bulletproof vests.

Flowport™: Golf ball aerodynamics theory points the way towards lower
distortion reflex ports. Dimples improve the way the air flows over the surface of
any object. In the case of reflex ports, they offer a significant improvement over
simply flaring the port ends in reducing air flow turbulence at each end of the
port; so you get less chuffing noise and less compression at high sound levels.
