The following sections give guidance on optimum positioning, but this may be modified in line with domestic constraints. Normal Stereo and Home Theatre Front Left and Right Applications (figure 2) Note: The assembly should be installed with the tweeter at the bottom. The speakers should be positioned with the tweeters at a little above ear height. [. . . ] This ensures that the frontal audio image is not distorted by changes of listener position or head movements. The orientation is less important in this application than in other cases. WARNING: The SignatureTM7NT speakers produce a static magnetic field that extends outside the speakers boundary. In addition, loosely fill the whole section of the wall cavity with wadding. Fibreglass and mineral wool matting supplied for heat insulation are suitable, but not closed cell foam or expanded polystyrene. Check that there is no debris that may fall into the speaker (especially in ceiling mount situations). 2 x Wall frame with swing out dogs · 1 x Accessory pack containing: 8 x Self-Tapping screws (for frame to PMK fixing) 8 x Machine screws (fixing baffles to wall frames) We suggest you retain the packaging for future use. Remove the grilles and baffles from the wall frames and, to avoid damage, keep them in their plastic bags (and preferably in the carton) away from the work area until you are ready to fit them.

Check that there is no conflict with other in-wall installations (pipe work, air conditioning, powercabling etc. In existing construction, use a stud-finding tool to map the wall construction accurately and a pipe detector to scan the proposed installation position. Avoid installing the speakers in the same cavity of the wall 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 15 litres (0. Use the template provided to mark out the correct size aperture, having regard to how the wall frame is to be lined up with any features such as door frames, and cut out the aperture neatly. Feed the pre-mount frame through the aperture and pull it forward so that it sits flat on the rear of the drywall and the inner part of the frame protrudes through the aperture. Screw, but do not tighten, 4 of the screws provided through the slots in the wall frame into the pilot holes in the pre-mount frame.

Use a separate twin cable from the amplifier terminals to each pair of speaker terminals (figure 5). [. . . ]
