Trace round the outer edge of the template and cut neatly just inside the line. To improve the mechanical integrity of the ceiling and reduce the likelihood of rattles, we recommend you apply a bead of wood glue or mastic along the joints between the back of the plasterboard 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. New drywall construction The speaker can be installed once the ceiling is completed in the same manner as retrofitting, but it is easier to position and cut the hole if the optional pre-mount kit is used before the plasterboard (sheetrock) 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 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 is attached to the studs and we recommend gluing 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. Damping the cavity Drape fibreglass or mineral wool matting at the back of the ceiling board, covering the aperture and extending at least 30cm (1 ft) around the speaker into open void. (figure 7) IMPORTANT: Ensure that the materials you use meet local fire and safety regulations. Fitting the speaker All connections should be made with the equipment switched off. Connect the cables, observing the correct polarity. With the grille removed, position the speaker in the aperture and screw in the 4 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 overtighten the screws as excessive distortion of the speaker frame may result. Adjusting the speaker The angle of the tweeter may be adjusted. This, in conjunction with rotating the whole speaker, allows you to optimise the sound dispersion in relation to the listening area. (figure 8) Direct the tweeter towards the listening area to improve high frequency definition and imaging if the speaker has to be mounted too far off line. Conversely, in surround applications, it may be desirable to point the tweeter away from the listening area to create a more diffuse sound field. The switch on the front baffle provides boost or cut to the speaker's high- frequency output level to compensate for listeners positioned severely off axis or a dull acoustic (boost) or highly reflective rooms (cut). (figure 9) Customising The frame has a paintable white semi-matte finish, ready if necessary to be re-finished to match your own 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.
