[. . . ] Figure 1 illustrates these positioning guidelines. Carton Contents Check in the carton for: Wall frame/baffle with driver units and crossover unit Grille with backing scrim fabric Paint Mask Mounting template 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. [. . . ] 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/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. 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. 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. Do not re-finish the drive units or baffle area behind the grille. Avoid touching the drive units, as damage may result. 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. [. . . ] 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. How to claim repairs under warranty Should service be required, please follow the following procedure: 1 If the equipment is being used in the country of purchase, you should contact the TNB authorised dealer from whom the equipment was purchased.
