Speaker Installation

The CT8.4 LCRS speaker is intended for use in home theatre front, centre and surround channel applications. More specifically it can also be used as the surround speaker option for the CT800 system when space constraints prohibit the use of the

CT8 DS. The speaker can be wall mounted in either vertical or horisontal orientation using the accessory brackets.

To use the wall bracket attach its two shorter elements to the speaker using the tapped holes in its back panel and the four supplied M6 bolts. Attach the longer bracket element to the wall in the appropriate position. Once the two bracket elements are securely attached the speaker can be hung on the wall. Figure 2 illustrates use of the wall bracket. Before using the bracket 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.

Regardless of the style of installation take care when lifting the speaker into position. It is unwieldy and heavy and best handled by two people working together.

A black fabric grille is attached via push-fit pegs.

Speaker Positioning

CT8.4 LCRS speakers used for the front 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 Figure 1.

A CT8.4 LCRS 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. See Figure 1.

CT8.4 LCRS speakers used for the surround channels in a home theatre system should be positioned above and to either side or behind the listening position. See Figure 1.

Stray Magnetic Fields

The speaker drive units create stray magnetic fields that extend beyond the boundaries of the cabinet. We recommend you keep magnetically sensitive articles (CRT television and computer screens, computer discs, audio and video tapes, swipe cards and the like) at least 0.5m (20 in) from the speaker. LCD and plasma screens are not affected by magnetic fields.

Connections

All connections should be made with the equipment switched off.

CT8.4 LCRS speakers have two pairs of binding post connection terminals and one Neutrik® Speakon® connection socket on their back panels. The binding post terminals provide quick and easy connection of stripped wires while Speakon® sockets provide a more secure and reliable connection method. Both Speakon® and binding post terminal connection methods provide the opportunity to bi-wire the speakers.

To connect the speakers in conventional single-wire mode using the Speakon® option, disassemble the Speakon® plug as shown in Figure 3a and connect the positive cable to the terminals marked +1 and +2 and the negative cable to the terminals marked -1 and -2. Incorrect connection can result in poor imaging and loss of bass. Once the plug is reassembled it can be inserted into the socket and locked by twisting clockwise.

To connect the speakers in conventional single-wire mode using the binding post terminals, insert a short length of stripped cable through the body of each terminal and tighten the terminal head. Connect the positive cable to one of the red terminals and the negative cable to the corresponding black terminal as illustrated in Figure 3b. Incorrect connection can result in poor imaging and loss of bass.

To connect the speakers in bi-wire mode using either the binding post terminals or the Speakon® socket

If the Speakon® option is to be used, disassemble the Speakon® plug as shown in Figure 4a and connect one pair of positive and negative cables to the terminals marked +1 and -1 and the second pair of positive and negative cables to the terminals marked +2 and -2. Ensure that positive cables are connected to the + terminals and the negative cables connected to the – terminals. Incorrect connection can result in poor imaging and loss of bass. Once the plug is reassembled it can be inserted into the socket and
