User manual B&W CWM 200

[. . . ] It is also our policy to make sure the advanced features pioneered on one product are incorporated into others we manufacture. However, no matter how good the speakers themselves, they must work well into the listening room and time spent on planning the installation will reap the reward of many hours listening pleasure. [. . . ] This ensures that the frontal audio image is not distorted by changes of listener position or head movements. The speakers should generally be placed behind and 0. 6m (2ft) or more above ear height. The orientation is less important in this application than in other cases. WARNING: The CWM speakers produce a static magnetic field that extends outside the cabinet boundary. As such They should not be placed within 0. 5m (20in) of equipment that may be affected by such a field, e. g. Cathode Ray Tubes in TVs and Personal Computers. FITTING THE WALL FRAME Existing Construction Position the template on the surface as required Mark around the outside of the template and cut the aperture neatly. All Methods (figure 2) Position the frame in the ceiling and screw in the 4 screws visible from the front of the frame. A certain amount of flexing of the frame is allowed to take up unevenness in the mounting surface, but do not over tighten the screws as excessive distortion of the frame may occur. CUSTOMISING The frame has a paintable white semi-matte finish, ready if necessary to be re-finished to match your own decor. Avoid touching the drive units, as damage may result. CONNECTIONS All connections should be made with the equipment switched off. Connect the red (+ve) terminal to the positive terminal of the amplifier and the black (-ve) to the negative.
