Warranty information
CCM6 Series ceiling mount speakers comprise a
baffle carrying the speaker drivers and crossover,
a mounting frame (with integrated bezel), and a
magnetically secured grille. The frame is connected
via side mounted terminals to the speaker cables, with
the baffle connecting automatically as it is inserted in
the frame.
All CCM6 Series speakers require clear depth behind
the sheetrock (plasterboard) of 140mm (5.51 in). The
diagrams above illustrate these dimensions.
Note: If CCM6 Series speakers are to be installed
in “new build” projects, pre-mount kits and back
boxes are available. Contact your local Bowers &
Wilkins retailer for more information.

Note: A square grille is optionally available for
CCM6 Series speakers. Contact your local
Bowers & Wilkins retailer for more information.
Before installing CCM6 Series speakers you should
ensure that the ceiling 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 ceiling construction and a pipe detector to scan the
proposed installation locations.

3. Positioning CCM6 Series Speakers
The appropriate position for CCM6 Series speakers
within the listening environment will depend on their
specific application:
Multi-channel Audio Applications
Note: The nature of the installation of ceiling
For applications where multiple CCM6 Series speakers
are to be used for multi-channel audio visual systems,
the front and centre speakers should be located
approximately 0.5m (20 in) in front of the plane of the
screen. The centre speaker should be on the centre
line of the screen and the front speakers each laterally
within approximately 0.5m (20 in) of the sides of the
screen. Surround channel CCM6 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 the acoustic
environment around each front and surround speaker
is similar.
speakers means that it is sometimes impractical
to locate them in an acoustically ideal position. In
these cases they should be located as close as is
practical to the ideal positions. Your local Bowers &
Wilkins retailer will be able to offer advice if required.
General Background Audio Applications:
For applications where single CCM6 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.
Note: CCM6 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.
Stereo Audio Applications:
For applications where a pair of CCM6 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.
The high frequency radiation characteristics of
some CCM6 Series models can be adjusted by
tilting their tweeters. In these cases, CCM6 Series
speakers should be oriented so that the red arrow
on the frame flange points towards the listening area.
Tweeter tilting is also accompanied on some models
by corresponding equalisation options selected via
a switch on the baffle. See Section 4.8 for more
information.
Note: Different acoustic environments might be,
for example, a bare wall and a heavily curtained
window.

4. Installing CCM6 Series Speakers
CCM663SR - CCM664SR
SURROUND
STEREO
To install a CCM6 Series speaker proceed as
described in the following paragraphs:
4.4 With the frame connected it may be lifted up into
the ceiling aperture. On speakers with tilting tweeters,
correct frame orientation must be established at this
stage: the red arrow on the frame flange should be
pointing towards the listening area.
Note: Always use high quality, low resistance
speaker cable. Low resistance is especially
important if the length of cable from amplifier to
speaker exceeds 5m. Your local Bowers & Wilkins
retailer will be able to offer advice on speaker cable
selection if required.
4.1 Using the supplied cut-out template, mark a
cut line on the existing ceiling. Check the cut line
defines the correct diameter. Cut along the line with
an appropriate tool to create a round aperture in the
ceiling.
Ensure that the four QuickDog™ (spring clamps) are
rotated so that they will pass through the aperture
then lift the frame up so that the flange is flush on the
ceiling. Take care that the cable is not trapped. Now
reach inside the aperture with one hand, rotate the
QuickDogs™ outwards and, using two fingers and
thumb, pull each QuickDog™ downwards so that the
frame is fixed securely. The diagram above illustrates
insertion of the frame.
4.3 Now connect the speaker cable to the spring
terminals on the side of the frame. Ensure that the
speaker connection polarity is correct: the cable
connected to the positive terminal on the amplifier
should be connected to the red spring terminal on the
frame. Similarly, the cable connected to the negative
terminal on the amplifier should be connected to the
black spring terminal on the frame. The diagram above
illustrates cable connection.
Note: Ensure that there is enough free space
internally adjacent to the aperture for the spring
clamps.
Note: To reduce the possibility of the ceiling buzzing
or rattling, adhesive mastic can be applied between
the studs and sheetrock in the vicinity of the
speaker aperture.
Note: To release a QuickDog™ push the metal tab,
located just below the finger platform, upwards.
When connecting a CCM664SR or CCM663SR in
surround mode, simply connect the speaker cable to
either the left or right set of terminals. Please ensure
that the switch on the back is set to surround.
4.2 If speaker cable is already present in the ceiling
space, pull the cable down through the aperture. If
speaker cables are not already installed this should be
done at this stage. It is likely that you will need to gain
access through the floor above to route the cables
through the ceiling space.
Note: If an amplifier is already connected to the
cable it should be switched off while connections
are being made to the frame.
Leave enough spare cable through the aperture to
ease connection to the speaker back box, but not so
much that it is likely to buzz or rattle when pushed
back up into the ceiling space. Approximately 1.0m
(3 ft) is appropriate.

4.5 If the frame flange is to be painted it should be
done at this stage. Any conventional, domestic paint
may be applied by brushing, rolling or spraying. Use
the supplied paint mask to avoid getting paint in the
cavity. Painting without using the paint mask risks
contamination of the internal connection terminals or
the grille attachment magnets. The diagram above
illustrates painting using the paint mask.
4.6 The baffle can now be fitted into the frame. Ensure
that the connector on the baffle is oriented correctly
with the connector in the frame. The baffle is held in
the frame by three push-lock fasteners. Push-lock
fasteners are secured by pushing the head inwards –
either with a thumb or a screwdriver. As they secure,
the fasteners will click. The baffle will then be secure in
the frame. The diagram above illustrates inserting the
baffle and securing the push-lock fasteners.
Note: If the grille is to be painted this should be
done “off-line” before it is fitted.
Note: Push-lock fasteners are released by turning
anticlockwise with a screwdriver.
Note: The bezel is loosely fitted to the frame when
the speaker is shipped and can come away during
handling. This is not a problem as the bezel is held
in position when the QuickDogs™ are secured.

selected on some CCM6 Series models. The options
are listed in the following table:
4.8 The grille can now be fitted. The grille is held in
place magnetically so simply needs to be aligned with
the groove in the frame flange where it will click into
place. The diagram above illustrates fitting the grille.

To tilt the tweeter simply hold it in one hand (taking
care not to touch the dome) and angle it towards the
listening position. Tilt angle indicators at 15° and 30°
are provided, indicated by the dots on the tweeter
body. The dots also correspond to the three way
equalisation switch settings. Match the switch setting
to the number of tilt dots. The diagram above illustrates
tilting the tweeter and selecting equalisation settings.
