Mounting through a suspended ceiling grid
On the rear of the enclosure install and tighten two 3/8-16-thread forged steel eyebolts (one is included) with a 3/8" flat washer under each. Cut two pieces of ordinary drop ceiling L angle (wall track) 23 3/4" long and screw them to the top and bottom of the enclosure with 3/4"-long sheet metal screws, as shown in Figure 10. Connect all of the wires and suspend the enclosure, face down, by the eyebolts in accordance with accepted safe rigging practice. Adjust the length of the rigging cables so the tips of the installed L angles just rest on the ceiling cross-tees. This stabilizes the enclosure from rocking. Trim the ceiling panel to fit the new opening(s) and drop into place. It is the installer’s responsibility to assure that the chosen rigging points are strong enough to support the load.
Warning: Never try to install this speaker in a suspended ceiling without proper rigging support!
