5. Lift and slide the speaker into position so that the screws at the ends of the
yoke line up with the T-nuts in the cabinet. It may be helpful to have a
second person assist with these steps.
Note: You may need to make audio cable connections to the rear of the
cabinet before the cabinet is slid fully into the yoke.
6. Push the four screws into the T-nut holes in the cabinet and tighten with a
Phillips screwdriver.
SECURING THE SAFETY CABLE:
Thread the loose end of the safety cable through a ferrule and then through
the cable hole provided on the yoke. Loop the cable back through the ferrule
and crimp firmly with a large pair of crimping pliers. (See photo below.)
Position the safety cable so it does not come in contact with any of the audio
connectors on the cabinet.
