Owner’s manual
Introduction
Thank you for purchasing Bowers and
Wilkins CCM speakers.
Since its foundation in 1966, the continuing
philosophy of B&W has been the quest for
perfect sound reproduction. Inspired by the
company’s founder, the late John Bowers,
this quest has entailed not only high
investment in audio technology and
innovation but also an abiding appreciation
of music and movies to ensure that the
technology is put to maximum effect.
These CCM speakers are intended for in-
ceiling applications. They feature
adjustment for tweeter angle and output
level so that their performance may be
tailored to a wide variety of practical
conditions.
However, no matter how good the speakers
themselves, they will not deliver their full
potential unless properly installed. Please
read through this manual fully. It will help you
optimise the performance of the system.
B&W distributes to over 60 countries
worldwide and maintains a network of
dedicated distributors who will be able to
help should you have any problems your
dealer cannot resolve.
Check the contents
This pack should contain:
2x Frame/baffle with drivers and crossover
2x Grille
2x Paint mask
2x Mounting template
Choosing the position
Check that there is no conflict with other
installations (pipe work, air conditioning,
power cabling etc.). In existing drywall
construction, use a stud-finding tool to
map the construction accurately and a pipe
detector to scan the proposed installation
position.
Ensure that there is enough clearance
behind the plasterboard (sheetrock) for the
clamps to swing out fully.
Avoid installing the speakers in the same
cavity as flimsy ducting, which may be
induced to rattle.
The speakers are designed to operate
satisfactorily in a wide range of cavity
volumes, ideally above 10 litres (0.4 cu ft),
so make sure the volume is not too
restricted.
The speakers are balanced for half-space
mounting (ie flush in a ceiling or soffit).
Placement near a wall/ceiling junction or in
a corner may give rise to too much bass
and a boomy quality to the sound. Try to
keep the speakers at least 0.5m (20in) from
wall/ceiling edges.
The following sections give guidance on
optimum positioning, but this may be
modified in line with domestic constraints.
WARNING: The speakers produce a static
magnetic field. They should not be placed
within 0.5m (20in) of equipment that may
be affected by such a field (eg Cathode
Ray Tubes in TVs and Personal
Computers).
Front speakers for audio or home
theatre
Best imaging for 2-channel is obtained
when the speakers are mounted in the
ceiling, making an angle between 40º and
60º at the centre of the listening position.
(figure 1)
For multi-channel home theatre the left and
right speakers should be approximately
0.5m (20 in) to the left and right of the
screen and about 0.5m (20 in) from the
plane of the screen or from the front wall in
the case of an audio-only installation.
(figure 2)
Surround speakers
The speakers should be positioned in the
ceiling about 0.5m (20 in) away from the
wall.
5.1 channel
The horizontal angle to the centre of the
listening position should be approximately
120º round from the centre of the screen.
(figure 3)
6.1 channel
Position two speakers to the sides in line
with the centre of the listening area and
one centrally behind the listeners (figure 4)
7.1 channel
Position two speakers to the sides in line
with the centre of the listening area and
two behind the listeners, subtending an
angle of approximately 40º. (figure 5)
Distributed audio
To maintain clarity and speech intelligibility,
it's important that listeners are never too far
off axis of the nearest speaker. The speaker
spacing will depend on the height of the
ceiling and the level of sound required.
More speakers played at a lower level will
give better clarity. We recommend that the
distance between adjacent speakers is no
more then 3 times the distance between
average ear height and the ceiling. For any
given spacing, there will be fewer weak
spots with a triangular grid than a
rectangular one. (figure 6)
PREPARING THE LOCATION
Choosing cable
Excessive resistance in the speaker cable
wastes power and alters the frequency
response of the speaker. Always try to keep
