CWM7.5

3. Positioning CWM7 Series Speakers

All CWM7 Series speakers require a clear depth of 102mm (4.02 in) from the front of the ceiling surface.

Note: The CWM7.3 can also be used in landscape orientation with aperture dimensions of 251mm (9.9 in) by 711mm (28 in) respectively height by width. No reservoir box is used with the CWM7.3 in landscape orientation.

Note: The reservoir box clearance is the clear distance within the wall above or below the aperture required to accommodate the reservoir box.

Before installing CWM7 Series speakers you should ensure that the wall 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 wall construction and a pipe detector to scan the proposed installation locations.

Note: CWM7 Series in-wall speakers will most often be installed in existing walls, however, if they are to be installed in newly constructed walls a pre- mount kit that aids appropriate wall construction is available. Contact your local Bowers and Wilkins retailer for more information.

The appropriate position for CWM7 Series speakers within the listening environment will depend on their specific application:

General Background Audio Applications:

For applications where single CWM7 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.

Stereo Audio Applications:

For applications where a pair of CWM7 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.

Multi-channel Audio Applications

For applications where multiple CWM7 Series speakers are to be used for multi-channel audio visual systems the left and right front speakers should be located either side of the screen approximately 0.5m (20 in) away. The centre channel speaker should be located either directly above or below the screen or, in the case of an acoustically transparent screen, directly behind. Surround channel CWM7 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.

Note: Different acoustic environments might be, for example, a bare wall and a heavily curtained window.

Note: The nature of the installation of in-wall 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: CWM7 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.
