Installation and Connections

CAUTION
• Do not mount the loudspeaker on a sloped ceiling.
• Largest supported wire size: 12 AWG
• Smallest supported wire size: 22 AWG
• Confirm that the ceiling to which the loudspeaker will be installed has sufficient
strength and the necessary thickness.
Even if the thickness is adequate, you must separately confirm the load bearing
capacity of the ceiling board. Supported ceiling thickness: 6 to 20 mm (0.24 to
0.79 inches)
• The C-rings are not for reinforcement. They are safety mechanisms. If the
loudspeaker is mounted to a weak ceiling, the ceiling may sag after a long period
of time.
• Reinforce the ceiling as appropriate because loudspeaker output may cause the
ceiling to resonate and impact sound quality.
• Be careful not to touch the diaphragm of the loudspeaker.

Cutting the Hole in the Ceiling
• Place the included template on the ceiling and draw the line for the
hole. Or use a hole cutter and cut the mounting hole in the ceiling.
Hole dimensions

CAUTION
Wear safety goggles to prevent dust and debris from getting in your eyes.

Connecting the Loudspeaker

This section describes how to connect the loudspeaker to the power amplifier and
other speakers. The connector for this loudspeaker consists of four terminals.
Terminal 1 is the "+" loop-through terminal, terminal 2 is "+", terminal 3 is "-", and
terminal 4 is the "-" loop-through terminal. Terminals 1 and 2 and terminals 3 and 4
are connected inside the loudspeaker.
Parallel connection
This connection method enables other speakers to work normally as long as their
wires are connected to the terminals even if one speaker has a problem.
Connect the wires for the next speaker to the same terminals that fasten the
previous speaker wires as shown in the diagram below.
