3. Positioning CWM7 Series Speakers
All CWM7 Series speakers require a clear depth of
102mm (4.02 in) from the front of the ceiling surface.
Note: The CWM7.3 can also be used in landscape
orientation with aperture dimensions of 251mm
(9.9 in) by 711mm (28 in) respectively height by
width. No reservoir box is used with the CWM7.3 in
landscape orientation.
Note: The reservoir box clearance is the clear
distance within the wall above or below the aperture
required to accommodate the reservoir box.
Before installing CWM7 Series speakers you should
ensure that the wall locations chosen are free of
obstructions such as pipe work, ducting or wiring that
will interfere with the installation. In existing dry-wall
construction, use a stud-finding tool to help you map
the wall construction and a pipe detector to scan the
proposed installation locations.
Note: CWM7 Series in-wall speakers will most often
be installed in existing walls, however, if they are
to be installed in newly constructed walls a pre-
mount kit that aids appropriate wall construction is
available. Contact your local Bowers and Wilkins
retailer for more information.
The appropriate position for CWM7 Series speakers
within the listening environment will depend on their
specific application:
General Background Audio Applications:
For applications where single CWM7 Series speakers
are required to operate independently to provide
background audio, they can be located substantially as
installation convenience and architecture dictate. The
only acoustic constraint to bear in mind is that corner
locations will result in significantly emphasised low
frequencies and should be avoided.
Stereo Audio Applications:
For applications where a pair of CWM7 Series
speakers is to be used for conventional stereo
reproduction, they should be located between 3m
(10 ft) and 5m (16.5ft) apart and a similar distance
in front of the listening area. Try to avoid corner
locations for the speakers and to ensure that acoustic
environment around each speaker is similar.
Note: Different acoustic environments might be,
for example, a bare wall and a heavily curtained
window.
Multi-channel Audio Applications
For applications where multiple CWM7 Series speakers
are to be used for multi-channel audio visual systems
the left and right front speakers should be located
either side of the screen approximately 0.5m (20 in)
away. The centre channel speaker should be located
either directly above or below the screen or, in the case
of an acoustically transparent screen, directly behind.
Surround channel CWM7 Series speakers should be
located just behind and either side of the listening
position.
Try to avoid corner locations for any of the speakers
and to ensure that acoustic environment around each
front and surround speaker is similar.
Note: Different acoustic environments might be,
for example, a bare wall and a heavily curtained
window.
Note: The nature of the installation of in-wall
speakers means that it is sometimes impractical to
locate them in the acoustically ideal positions. In
these cases they should be located as close as is
practical to the ideal positions. Your local Bowers
and Wilkins retailer will be able to offer advice if
required.
Note: CWM7 Series drive units create stray
magnetic fields. We recommend that magnetically
sensitive items such as CRT screens and magnetic
cards for example, are kept at least 0.5m (20 in)
from the speaker. LCD, OLED and plasma screens
are not affected by magnetic fields.
