[. . . ] There are insulation materials installed inside each back box that are essential for its fire-rating properties. Please ensure that this insulation is not shifted inside or removed from the back box. Hole Plug Vertical Orientation Horizontal Orientation Figure 1. Horizontal NOTE: Make sure the safety tab is fully recessed and does not come in contact with the wall behind the loudspeaker back box. Depending on the orientation, install the conduit set-screw connector and the hole plug, as shown in Figure 3. Conduit Set-Screw Connector Figure 3. [. . . ] Conduit set-screw connector/hole-plug installation lf conduit use is required, attach the conduit to the conduit set-screw connector and pull the speaker wire through the conduit and conduit set-screw connector and into the back box. lf conduit use is not required, pass the speaker wire through the conduit set-screw connector into the back box. Pull enough speaker wire into the back box to provide an easy connection to the speaker. When not using a conduit, you may use a UL-approved strain-relief cable clamp of the same hole diameter, instead of the supplied conduit set-screw connector. Position the back box at the desired location against the studs, using the loudspeaker cutout on its baffle as a guide of where the speaker will be located, and check for possible clearance/interference issues, repositioning if necessary. Before securing the back box to the stud, make sure that the back box is equally spaced away from the stud on both sides. Attach one side of the back box to the stud, using an appropriate screw through one of the center predrilled holes. Install the remaining screws through the predrilled holes into the studs. After the 5/8" (16mm) or thicker drywall is installed, cut the opening for the speaker by using the outside rim of the back box as a template. Once the rails are in the right spot both vertically and horizontally, tighten the lock nut on the screw with a wrench or socket. Ensure that the lock nuts on both sides of the back box are tightened and the rail cannot move. lf conduit use is required, attach the conduit to the conduit set-screw connector and pull the speaker wire through the conduit and conduit set-screw connector and into the back box. Tighten the conduit set-screw connector to the conduit with the screws on the connector. lf a conduit is not used, pass the speaker wire through the conduit set-screw connector into the loudspeaker back box. Pull enough speaker wire into the back box to provide easy connection to the speaker. When not using a conduit, you may use a UL-approved strain-relief cable clamp of the same hole diameter, instead of the supplied conduit set-screw connector. lf the safety strap is used, attach the safety strap per the local building codes to an approved point on the building structure and attach it to the hanging tab on the back box. Both attachment points need to meet the requirements of the local building codes, and it is the responsibility of the customer/installer to ensure that these codes are met.

The loudspeaker can now be installed in the back box per the loudspeaker's instructions. 19-5/16" x 12-5/8" (491mm x 320mm) * for reference only To perform the installation step below, you will need to purchase two sets of carriage bolts and nylon lock nuts (not included).
