[. . . ] 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. 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. [. . . ] Always try to keep the resistance as low as possible with the loop resistance preferably below 0. 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. 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/caulking 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. Allow enough length to comfortably connect the speaker, but not too much, as the excess may rattle against the structure. 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. Qxd 8/11/07 09:58 Page 4 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. Terms and Conditions 1 The warranty is limited to the repair of the equipment. Neither transportation, nor any other costs, nor any risk for removal, transportation and installation of products is covered by this warranty. This warranty will not be applicable in cases other than defects in materials and/or workmanship at the time of purchase and will not be applicable: 2 3 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. [. . . ] 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. [. . . ]
