[. . . ] (203 mm) from either end and equidistant from each side edge. (273 mm) tile bridge hole with the spot marked as the center, and position the metal tile bridge flat against the ceiling tile with the ends of the tile bridge aligned to the side edges of the ceiling tile. Carefully, so as not to damage the ceiling tile, temporarily secure the tile bridge in-place with adjustable torsion clamps such as C-clamps. Guide the blade of a RotoZip® RZ01, or similar rotary cutting tool, against the edge of and completely around the 10. 75 in. (273 mm) tile bridge hole, cutting the ceiling tile hole. Remove the torsion clamps and tile bridge from the ceiling tile. Install the ceiling tile in the ceiling's T-grid. Install the tile bridge on top of the ceiling tile, and align the tile bridge hole with the newly cut ceiling tile hole. Pull the wiring and or flex conduit through the tile bridge and ceiling tile holes. Attach one end of the S-hook to the SLC308-8T's metal strain relief strap and rest the other end of the S-hook, through the mounting hole, on the top surface of the tile bridge. Connect the audio transmission (-) wire (usually black) to the black wire of the SLC308-8T, and connect the audio transmission (+) wire to the red wire of the SLC308-8T. Secure a sufficient insulator cover over these connections. Note: Proper rated wire-nuts are recommended to insulate these connection points. 12. If flex conduit is used, pack the excess wire into the conduit (including the wire nuts), and secure the flex conduit with the ½ in. Remove the S-hook and gently push the SLC308-8T (and excess conduit or wire) up into the hole and tighten the three mounting screws, causing the dogleg arms to swing out and anchor the enclosure to the metal tile bridge. Snap on the metal grille. ARCHITECT'S AND ENGINEER'S SPECIFICATIONS The loudspeaker system shall be an in-ceiling design, consisting of a Duplex® 8 in. (203 mm) diameter cone woofer and a 3 in. This loudspeaker component shall have a power rating of 16W AES (64W peak). [. . . ] The peak output level of the system is calculated based on the sensitivity and the peak power handling capabilities of the system. The coverage angles for the loudspeaker are taken as the -6 dB points of the directivity response and averaged from 500 Hz to 16 kHz. The minimum impedance of the loudspeaker is taken over its intended band of operation.
