Note: CCM7 Series speaker dispersion can be
adjusted to accommodate use in centre or left,
right and surround channel roles. The dispersion
is adjusted via a switch on the cross-over. See
Paragraph 4.7 for more information.
Note: The nature of the installation of ceiling
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.

the line with an appropriate tool to create a square
aperture in the ceiling.
Note: Ensure that there is enough free space
internally adjacent to the aperture for the back box
clamps to rotate fully. 20mm (0.79 in) free space is
required.
Note: To reduce the possibility of the ceiling buzzing
or rattling, adhesive mastic can be applied between
the studs and sheetrock in the vicinity of the
speaker aperture.
