Bowers & Wilkins CM6 Speaker User Manual


 
CM6
Floorstanding loudspeaker system
The 3-way CM6 offers the degree of midrange clarity and detail that only B&W's unique
FST driver can deliver. Housed in its own chamber within the cabinet, this remarkable
midrange driver is isolated from the bass producing part of the system. There the twin
aluminium cone specialist bass drivers are supplemented by a rear-firing Flowport to
give an enhanced dynamic performance over the CM4.
Nautilus-style tube loading of the tweeter is a given, ensuring efficient absorption of
unwanted radiation from the rear of the diaphragm. Extending well above the bounds of
human hearing, the tweeter is fully capable of exploiting SACD and DVD-A formats.
In common with all CM models, the cabinet is elegantly finished by a brushed aluminium
front panel and a choice of Maple, Rosenut or Black Ash real wood veneers.

Technical highlights
Nautilus
TM
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.
