5. MOUNTING HARDWARE INSTALLATION
Before mounting the speaker, determine the most appropriate method for the existing ceiling structure.
Be sure to use an optional HY-TB1 Tile Bar Bridge in combination with the supplied ceiling
reinforcement ring.
[Installation view on Drop Ceilings]
Because the bridge rails are 603 mm (23 47 /
64
") in length, be sure to match them to the ceiling tile size during
installation.
Caution
Set the bridge rails so that both ends fit securely into the T-grids, even if the ceiling tile accidentally falls off.
