Prepare Ceiling

Refer to Figure 1.

1. Use the template provided to mark and cut a hole (1) in the ceiling where the loudspeaker is to be installed. For a frame-construction ceiling, skip to Wire the Loudspeakers.
2. Install two V-rails (2), one on each side of the hole, and supported by the suspended-ceiling support rails (3).
3. Install the C-ring (4) over the hole, using the V-rails as support. Make sure the clips on the C-ring are properly fitted over the V-rail.
4. Use sheet-metal screws (5) to secure the C-ring to the V-rails.

Wire the Loudspeakers

Refer to Figure 2.

1. Pass the wires down through the conduit/stress-relief clamp. Leave enough slack wire for making connections. Carefully tighten the clamp over the wires or conduit.
2. Wire the Euro-style plug (1) as shown in Figure 3.
3. Slide the cover (4) over the connector and secure with the Phillips screw.
