4.Installing CWM3 Series Speakers
To install a CWM3 Series speaker, proceed as described in the following paragraphs:
4.1 Using the supplied aperture template, mark a cut line on the wall. Check the cut line defines the correct aperture dimensions. Cut along the line with an appropriate tool to create a rectangular aperture in the wall.
Note: Ensure that there is enough free space internally adjacent to the aperture for the dog clamps.
Note: To reduce the possibility of the wall buzzing or rattling, adhesive mastic can be applied between the studs and sheetrock in the vicinity of the speaker aperture.
4.2 If speaker cable is already present in the wall, feed the cable 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 through the wall space.
Leave enough spare cable through the aperture to ease connection to the speaker, but not so much that it is likely to buzz or rattle when pushed back 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 crossover board. 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 speaker. Similarly, the cable connected
to the negative terminal on the amplifier should be connected to the black spring terminal on the speaker. Diagram 3 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 back box.
4.4 With the speaker connected to the cable, it can be inserted into the wall aperture. Ensure that the four dog clamps are rotated inwards so that they can pass through the aperture, and then hold the speaker flange flush to the wall. Take care that the connection cable does not become trapped anywhere.
To secure the speaker use a Phillips screwdriver inserted through the
Note: If the wall is to be painted after the speakers have been installed, the supplied paint mask should be used.
4.5 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. Diagram 5 illustrates fitting the grille.
The CWM3 Series speaker is now installed and ready for use.
