CCM7 Series ceiling mount speakers comprise a  
baffle carrying the speaker drivers and crossover,  
an integrated back-box and front flange, and a  
magnetically secured grille. The back box is connected  
via external terminals to the speaker cables with the  
baffle connecting automatically as it is inserted in the  
back box.  
The appropriate position for CCM7 Series speakers  
within the listening environment will depend on their  
specific application:  
General Background Audio Applications  
For applications where single CCM7 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.  
Environmental Information  
All Bowers & Wilkins products are  
designed to comply with international  
CCM7 Series require a ceiling cut-out aperture of  
332mm x 332mm (13.07 in x 13.07 in) and a minimum  
clear depth of 194.5mm (7.66 in) from the front of the  
ceiling surface.  
directives on the Restriction of Hazardous  
Substances (RoHS) in electrical and electronic  
equipment and the disposal of Waste Electrical  
and Electronic Equipment (WEEE). These symbols  
indicate compliance and that the products must be  
appropriately recycled or processed in accordance  
with these directives. Consult your local waste disposal  
authority for guidance.  
Before installing CCM7 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.  
Stereo Audio Applications  
For applications where a pair of CCM7 Series speakers  
is to be used for conventional stereo reproduction, they  
should be located between 3m (10 ft) and 5m (16.5 ft)  
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. The diagram above illustrates this  
application.  
Some stages of the CCM7 Series installation process  
are best carried out by two people working together.  
Note: Different acoustic environments might be,  
for example, a bare wall and a heavily curtained  
window.

4. Installing CCM7 Series Speakers  
Multi-channel Audio Applications  
In all cases CCM7 Series speakers should be oriented  
so that their tweeters face generally towards the  
listening area. Speaker orientation is defined by the  
installed orientation of the back box. See Section 4.  
To install a CCM7 Series speaker proceed as  
described in the following paragraphs:  
For applications where multiple CCM7 Series speakers  
are to be used for multi-channel audio visual systems,  
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 CCM7 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. The  
diagram above illustrates this application.  
4.1 Using the supplied cut-out template, mark a cut  
line on the existing ceiling. Check the cut line defines  
the correct 332mm x 332mm dimensions. Cut along  
the line with an appropriate tool to create a square  
aperture in the ceiling.  
Note: CCM7 Series speaker dispersion can be  
adjusted to accommodate use in centre or left,  
right and surround channel roles. The dispersion  
is adjusted via a switch on the cross-over. See  
Paragraph 4.7 for more information.  
Note: Ensure that there is enough free space  
internally adjacent to the aperture for the back box  
clamps to rotate fully. 20mm (0.79 in) free space is  
required.  
Note: The nature of the installation of ceiling  
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: Different acoustic environments might be,  
for example, a bare wall and a heavily curtained  
window.  
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: CCM7 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.

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.  
4.4 Now connect the speaker cable to the spring  
terminals on the side of the back box, first looping the  
cable around the strain relief bar. A second person  
will be required to hold the back box while the cable  
is connected. The diagram above illustrates the cable  
connection.  
4.5 With the back box connected it may be lifted up  
into the ceiling aperture. Correct back box orientation  
must be established at this stage: the red arrow on  
the back box flange should be pointing towards the  
listening area.  
Ensure that the clamps are retracted so that they will  
pass through the aperture then lift the back box up so  
that the flange is flush on the ceiling. Take care that the  
cable is not trapped. One person should hold the back  
box in place while a second tightens the eight clamp  
screws. The diagram above illustrates insertion of the  
back box.  
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 (40  
in) is appropriate.  
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 back box. Similarly, the cable  
connected to the negative terminal on the amplifier  
should be connected to the black spring terminal on  
the back box.  
Note: Always use high quality, low resistance  
speaker cable. Low resistance is especially  
important if the length of cable from amplifier to  
speaker exceeds 5.0m. Your local Bowers and  
Wilkins retailer will be able to offer advice on  
speaker cable selection if required.  
Note: If an amplifier is already connected to the  
cable it should be switched off while connections  
are being made to the back box.  
4.3 CCM7 Series speaker back boxes are fitted with  
a safety hook feature that enables a safety chain or  
cable to be attached and then secured to a structural  
element within the ceiling – typically a stud (joist). We  
strongly recommend the safety hook feature is used.  
The diagram above illustrates the use of the safety  
hook.

4.6 If the back box 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  
back box 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.  
4.7 If the speaker is to be used in the centre channel  
role in a multi-channel system, select the centre  
position on the cross-over mounted dispersion switch.  
In all other applications select the left/right position  
on the switch. The diagram above illustrates the  
dispersion switch.  
Note: If the grille is to be sprayed this should be  
done “off-line” before it is fitted.

4.8 The baffle can now be lifted up into the back box.  
Ensure that the connector on the baffle is oriented  
correctly with the connector inside the back box.  
The baffle is held in the back box by four 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.  
4.9 The grille can now be fitted to the baffle. It is held in  
place magnetically so simply needs to be aligned with  
the groove in the back box flange where it will click into  
place. The diagram above illustrates fitting the grille.  
The CCM7 Series speaker is now installed and ready  
for use.  
With one person holding the baffle in place, a second  
person can push and secure the four push-lock  
fasteners. The fasteners will click three times. The  
baffle will then be secure in the back box. The diagram  
above illustrates inserting the baffle and securing the  
push-lock fasteners.  
Note: Push-lock fasteners are unsecured by turning  
them 45° using a screwdriver.
