Speaker Installation

CT700 Series speakers can either be installed within
existing or custom designed home theatre system
cabinets, or wall mounted using a variety of brackets.
If the speakers are to be installed within a cabinet it is
important to ensure that it is capable of carrying their
weight and that it is structurally sound. Significant
vibration of the cabinet panels may seriously affect the
subjective performance of the speakers. Figure 1
illustrates the installation of three CT700 Series
speakers in a home theatre cabinet showing the
recommended dimensions between the speakers and
space around them.
Adhesive rubber feet are supplied for attachment to the
underside of the speakers in order both to protect the
cabinet finish and to reduce vibration. Attach one
adhesive foot at each underside corner of the speakers.
If gaps wider than approximately 20mm (3/4 inch)
remain around a speaker when it has been installed in a
cabinet, the acoustic performance will be improved if
the gaps are filled. Use carefully cut pieces of
upholstery or acoustic foam to fill the gaps as far back
as is practical and flush with the front panel of the
speaker. Only use foam with an appropriate fire safety
rating.
CT700 Series speakers can also be wall mounted using
one of two methods.

Wall Brackets:
The speakers incorporate 4 M6 tapped inserts in their
back panels for attachment of the two brackets
supplied. Always use both brackets. Use the supplied
M6 bolts to attach the brackets to the back of the
speaker. The two supplied adhesive rubber spacers can
be used to cushion the speaker against the wall.
Figure 3 illustrates use of the brackets. Before using the
brackets ensure that the wall and fixings are capable of
supporting the weight of the speaker. B&W can accept
no liability for any failure of wall and/or fixings.
Ball-joint Brackets:
The speakers incorporate 4 M6 tapped inserts in their
undersides that enable the speakers to be wall-
mounted using adjustable ball-joint style mounting
brackets designed for 127mm x 69.9mm (5 in x 2.75 in)
mounting hole centres. Your dealer or local B&W
distributor will be able to advise you on the selection of
appropriate brackets.
To attach a ball-joint style bracket to a CT700 Series
speaker first securely attach the socket plate to the
underside of the speaker. Figure 4 illustrates this
procedure.
Once the socket plate is attached to the speaker, the
assembly may be connected to the ball component
attached to the wall. Ensure that the manufacturer's
instructions for attaching the bracket to the wall are
followed correctly and that the wall and fixings are
capable of supporting the weight of the speaker. B&W
can accept no liability for any failure of wall and/or
fixings.
Regardless of the style of installation take care when
lifting the speakers into position. They are unwieldy and
heavy and best handled by two people working
together.
The black fabric grilles are attached by magnets and
may be removed if desired. Take care not to touch the
drive units when removing or replacing the grilles.

Speaker Positioning

CT700 Series speakers used for the front left and
right channels in a home theatre system should be
positioned one either side of the screen on the
horizontal centre-line. They should be within
approximately 0.5m (20 in) of the sides of the screen
to help keep the sound image in scale with the visual
image. See Figures 1 and 2.
A CT700 Series speaker used for the centre channel in
a home theatre system should be positioned centrally
either directly above or below the screen. In the case
of acoustically transparent screens, the centre channel
speaker should be positioned centrally behind the
screen.
CT700 Series speakers used for the surround
channels in a home theatre system should be
positioned above and to either side or behind the
listening position.
