Bowers and Wilkins CM-7 Brochure

CM7

Like its CM siblings, the CM7’s great strength is stereo music
reproduction. A high technology, genuine three-way driver line-up,
compromising a Kevlar®/paper cone bass unit, Kevlar® cone FST
midrange unit and Nautilus™ tube-loaded aluminium dome tweeter.
These endow the CM7 with an ability to portray musical scale from
a whispered lyric to an orchestral crescendo without distortion or
compression. The ear-tuned, low-order crossover circuits, made possible
by the remarkably wide bandwidth of the CM7 drivers, ensure that music
is portrayed as a seamless, cohesive whole. Flowport™ technology
to minimise turbulence, and a bass driver featuring magnet system
technology that reduces distortion, mean that CM7 bass is extended,

fast and tuneful. An optional port sleeve that modies the low frequency

response allows positioning of the speaker right up close to walls without
musical compromise. The CM7’s Nautilus™ tweeter extends the top end
all the way to 50kHz and beyond.

The CM7’s tall, slim enclosure is a classically manufactured and
exquisitely veneered expression of traditional cabinet making and
provides a visually understated and mechanically rigid environment

for the drivers. Real wood nishes in Wenge, Rosenut and Maple are

available. Also, because the black or dark grey fabric grille is magnetically
attached, removing it reveals no unsightly grille mounting features.
