Owner’s manual
Introduction
Thank you for purchasing Bowers and
Wilkins CWM LCR8 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.
The CWM LCR8 is an audiophile quality in-
wall speaker that may be used in vertical or
horizontal orientation, the latter aesthetically
better for centre channel applications.
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
The outer carton should contain:
In pack 1:
Wall frame,
Grille with fabric scrim backing,
Mounting template,
Paint mask.
In pack 2:
Baffle with drive units and crossover,
Fixing screws.
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. Refer to the section
drawing of the speaker and 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
20 litres (0.7 cu ft), so make sure the
volume is not too restricted by cross studs.
This is particularly important when the
speaker is installed in horizontal orientation
for centre channel applications. In order to
fit the speaker horizontally, part of one
vertical stud will have to be removed and
this will necessitate the use of two cross
studs to maintain the strength and integrity
of the wall.
In solid wall construction, be prepared to
provide a cavity in the wall that extends
outside the boundaries of the speaker's
frame, otherwise bass performance will be
compromised. 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. As such 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 wall
in vertical orientation, with the tweeters
approximately at ear height and 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) from the edges of the screen
and they and the centre speaker should be
as near the centre height of the screen as
possible. For a centre speaker, horizontal
orientation is normally preferred for
aesthetic reasons and you should choose
between above or below screen mounting
depending on which is nearer ear height.
(figure 2)
Surround speakers
The speakers should be positioned with the
tweeters 60cm (2 ft) or more above head
height.
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)
