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"lomg sheet metal screws, as shown in Figure 26. Connect all 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! Step 5: Test System Operation After all connections are made test the complete system operation. 14 contains a troubleshooting guide to assist in locating a variety of speaker related problems.
