Introduction

The CWM Cinema 6 is primarily intended for home theatre application as a centre channel speaker but it may equally well be used as front left and right or surrounds or for 2-channel audio.

No matter how good the speakers themselves, they will not deliver their full potential unless properly installed. Please read through this manual fully. It will help you optimise their performance.

The CWM Cinema 6 speaker may be installed during construction of the studwork wall or at a later date. If possible, installation during construction of the wall is preferred however the CWM Cinema 6 pre-mount kit will be required.

Speaker Positioning

Check that there is no conflict with other installations (pipe work, air conditioning, power cabling etc.). In existing drywall construction, use a stud-finding tool to map the construction accurately and a pipe detector to scan the proposed installation position.

Refer to the section drawing of the speaker and ensure that there is enough clearance behind the plasterboard (sheetrock) for the clamps to swing out fully.

Avoid installing the speakers in the same cavity as flimsy ducting, which may be induced to rattle.

The speakers are designed to operate satisfactorily in a wide range of cavity volumes, ideally above 20 litres (0.8 cu ft), so make sure the volume is not too restricted by cross studs.

In solid wall construction, be prepared to provide a cavity in the wall that extends outside the boundaries of the speaker's frame, otherwise bass performance will be compromised.

The speakers are balanced for half-space mounting (ie flush in a wall, ceiling or soffit). Placement near a wall/ceiling junction or in a corner may give rise to too much bass and a boomy quality to the sound. Try to keep the speakers at least 0.5m (20in) from wall/ceiling edges.

The following sections give guidance on optimum positioning, but this may be modified in line with domestic constraints.

Home Theatre Centre Channel Applications

The ideal position for a centre channel speaker is behind the centre of the screen, however this can only be realised when using an acoustically transparent projection screen. In most cases the centre speaker will be positioned in a laterally central position either directly above or directly below the screen. Choose the position that is nearest ear height. Figure 1 illustrates these positioning guidelines.

Home Theatre Front Channel Applications and 2-channel audio

For multi-channel home theatre the left and right speakers should be approximately 0.5m (20 in) to the left and right of the screen and as near the centre height of the screen as possible. Figure 2 illustrates these positioning guidelines.

Best imaging for stereo is obtained when the speakers are mounted in the wall approximately at ear height and making an angle between 40^ and 60^ at the centre of the listening position.

Home Theatre Surround Channel Applications

The speakers should be positioned 60cm (2 ft) or more above head height.

5.1 Channel: The horizontal angle to the centre of the listening position should be approximately 120^ round from the centre of the screen. Figure 3.1 illustrates this arrangement.
6.1 Channel: Position two speakers to the sides in line with the centre of the listening area and one centrally behind the listeners Figure 3.2 illustrates this arrangement.
7.1 Channel: Position two speakers to the sides in line with the centre of the listening area and two behind the listeners, subtending an angle of approximately 40^ . Figure 3.3 illustrates this arrangement.

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.

Preparing For Installation Choosing cable

Excessive resistance in the speaker cable wastes power and alters the frequency response of the speaker. Always try to keep the resistance as low as possible with the loop resistance preferably below 0.5 ohms for non-critical applications and below 0.2 ohms for best results. Use the table of figure 7 to calculate the minimum gauge of cable required.

Fitting The Wall Frame/Baffle (existing wall construction/retrofit)

Figure 4 illustrates this procedure.

Position the template at the desired location of the speaker. The template is marked with both vertical and horizontal centre lines to aid alignment.

Trace round the outer edge of the template and cut neatly just inside the line.

To improve the mechanical integrity of the wall and reduce the likelihood of rattles, we recommend you apply a bead of mastic/culking along the joints between the back of the plasterboard (sheetrock) and the studs in the vicinity of the speaker.

Run the cable to the aperture, allowing enough length to comfortably connect the speaker, but not too much, as the excess may rattle against the structure.

Fitting the Wall Frame/Baffle (new drywall construction)

Figure 5 illustrates this procedure.

The speaker can be installed once the wall is completed in the same manner as retrofitting, but it is easier to position and cut the hole if the optional premount kit (PMK) is used before the plasterboard is fitted.

Staple or nail the PMK to the studs as described in the instructions with the kit. Run the cable and secure it to the fixing point on the PMK. Allow enough length to comfortably connect the speaker, but not too much, as the excess may rattle against the structure.

Results are affected by how well the plasterboard (sheetrock) is attached to the studs and we recommend you apply a bead of mastic/culking as well as screwing or nailing the panels to the studs in the vicinity of the speaker.

Once the board is fitted, the inner flange of the PMK serves as a guide for a hole router or saw.

If extra acoustic isolation to adjoining rooms is required or some protection against the spread of fire, use the optional back box in place of the PMK. Follow the instructions with the back box for fitting and running the cable.

When fitting the plasterboard (sheetrock), use mastic/caulking between the sheets and the back box to avoid rattles. Rout or saw out the speaker aperture using the back-box flange as a guide. Depending on the diameter of the router, you may need to square off the corners with a saw.

Fitting the Wall Frame/Baffle (solid wall construction)

In order for the bass performance not to be compromised, the speaker requires a cavity volume of at least 20 litres (0.8 cu ft). This means that, in a standard 10cm (4 in) thick wall, the cavity will extend beyond the boundaries of the speaker frame. It is possible to provide this cavity simply by using a lintel, covering the hole with plasterboard (sheetrock) and fitting the speaker as described above for retrofitting into a drywall. (Figure 6) However, the back box provides a useful means of defining a minimum volume.

Follow the instructions with the back box for fitting and running the cable. If using a wet plaster finishing method, first apply a thin layer of PVA adhesive (polyvinyl-based caulking) onto the back box before plastering to avoid rattles as a result of the plaster shrinking away from the back box as it dries.

If using plasterboard (sheetrock), stick the sheets to the surfaces of the back box using flexible mastic/-caulking. Rout out the aperture using the flange as a guide. Depending on the diameter of the router, you may need to square off the corners with a saw.

In all cases, we recommend not using cement or mortar to fix the back box into the brick or block-work. Rattles are best avoided by using flexible mastic/caulking and wedges.

Damping the Wall Cavity

Fill the wall cavity or back box, but not the space immediately behind the speaker, with unlined fiberglass or mineral wool matting. The packing density should be just enough to comfortably prevent the material from dropping or sagging over time. In an open wall cavity, fill to a distance of at least 30cm (1 ft) above and below the speaker.

IMPORTANT: Ensure that the materials you use meet local fire and safety regulations.

Connecting and Fitting the Speaker (all installation types)

All connections should be made with the equipment switched off.

Connect the cable, observing the correct polarity.

With the grille removed, position the speaker in the aperture and screw in the 6 screws visible from the front. These screws automatically swing out clamping dogs that locate behind the mounting surface. Ensure that they have located properly before fully tightening the screws. 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 speaker frame may result.

Customising

The frame has a paintable white semi-matte finish, ready if necessary to be re-finished to match room decor. Fit the paint mask before re-finishing. Do not re-finish the drive units or baffle area behind the grille. Avoid touching the drive units, as damage may result.

Before painting the grille, peel off the fabric scrim from the back, otherwise the pores will get clogged and the sound will be impaired. If the scrim does not stay in place properly when replaced, spray the back of the grille mesh (NOT the scrim) with a light coating of 3M SprayMount adhesive or similar.

Fine Tuning

If the sound is too bright, increasing the amount of soft furnishing in the room (heavier curtains for example) may help balance the sound. Conversely, reducing the amount of soft furnishing may help brighten a dull sound.

Some rooms suffer from "flutter echoes" - echoes that "bounce" between parallel room boundaries. Flutter echoes can colour the sound of the speakers in the room. Test for flutter echoes by standing in the middle of the room and clapping your hands. Flutter echoes can be reduced by placing irregular shaped items or non-reflective surfaces - bookshelves, rugs or pictures for example - on one of the offending walls or floor.

Running-in Period

The performance of the speaker will change subtly during the initial listening period. If the speaker has been stored in a cold environment, the damping compounds and suspension materials of the drive units will take some time to recover their correct mechanical properties. The drive unit suspensions will also loosen up during the first hours of use. The time taken for the speaker to achieve its intended performance will vary depending on previous storage conditions and how it is used. As a guide, allow up to a week for the temperature effects to stabilise and 15 hours of average use for the mechanical parts to attain their intended design characteristics.

However, longer run-in periods (as long as a month) have been reported and there is evidence to suggest that this has little to do with the speaker changing and more to do with the listener getting used to the new sound. This is especially so with highly revealing speakers such as these where there may be a significant increase in the amount of detail compared with what the listener has previously been used to; the sound may at first appear too "up front" and perhaps a little hard. After an extended period of time the sound will seem to mellow, but without losing clarity and detail.
