4.2 If speaker cable is already present in the wall
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 oor above to route the cables
down into the wall cavity.
Leave enough spare cable through the aperture to
ease connection to the speaker frame, but not so
much that it is likely to buzz or rattle when pushed
back up into the wall space. Approximately 1.0m (3 ft)
is appropriate.
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.
4.3 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 amplier
should be connected to the red spring terminal on the
frame. Similarly, the cable connected to the negative
terminal on the amplier should be connected to the
black spring terminal on the frame. The diagram above
illustrates cable connection.
Note: If an amplifier is already connected to the
cable it should be switched off while connections
are being made to the frame.
4.4 With the frame connected it may be inserted into
the wall aperture. Ensure that the QuickDogs™ (spring
clamps) are rotated so that they will pass through the
aperture then insert the frame up so that the ange
is ush on the wall. Take care that the cable is not
trapped. Now reach inside the aperture, rotate the
QuickDogs™ outwards and, using two ngers and
thumb, pull each spring clamp downwards so that the
frame is xed securely. There are four QuickDogs™ on
the CWM652 and six on the CWM663 and CWM664.
The diagram above illustrates insertion of the frame.
Note: To release a spring clamp push the metal tab,
located just below the finger platform, upwards.
4.5 If the frame ange 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.
Note: If the grille is to be painted this should be
done “off-line” before it is fitted.
