4.2If 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 floor 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.
4.3Now 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: If an amplifier is already connected to the cable it should be switched off while connections are being made to the frame.
4.4With 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 flange
is flush on the wall. Take care that the cable is not trapped. Now reach inside the aperture, rotate the QuickDogs™ outwards and, using two fingers and thumb, pull each spring clamp downwards so that the frame is fixed 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.
4.5If 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.
Note: If the grille is to be painted this should be done
