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.
