9.3. Joining the Enclosure to the Rigging Frame

Flying Plates are mounted at both the front and rear of the enclosure’s sides. Follow the procedure below to mount the enclosure to the Rigging Frame, as shown in the assembly diagrams.

Fix a supplied Joint Plate securely to the left side of the Rigging Frame and another to the right side of the enclosure, each using 4 supplied bolts with plain washers and spring washers.

Before securing the Joint Plate, determine whether the enclosure’s horn will face right or left. (This is not required for the SR-A18B Subwoofer.) When suspending the subwoofer, install the system so that the subwoofer is positioned at the top (directly below the Rigging Frame).
