The subwoofer can be suspended using the included aircraft cables (see “Aircraft cable
installation”) or, optionally, with threaded rods acquired locally (see
Threaded rod
installation on page 10).
Aircraft cable installation
Suspend the subwoofer above a false ceiling using the included aircraft cables as follows:
Remove ceiling tile and install suspension cables.
For installation with optional threaded rods, see Threaded rod installation .
1. Determine where the subwoofer is to be suspended and its orientation above the
suspended ceiling.
NOTE: Remember that the sound from the unit is directed out the port. Therefore,
although you can suspend the subwoofer in any horizontal orientation, the port
needs to be pointed into the listening space.
Consider the following as you make this determination:
• Possible acoustical reinforcement (see Acoustical Reinforcement on page 5).
•
The size (length, width, and height) of the subwoofer.
• The desired location of the woofer port. Ensure that the center of the port tube will
be at least 5-3/16 inches (13.7 cm) from the edge of suspended ceiling tile once
that tile is installed.
NOTE: This positioning ensures that the grille adapter and C-ring fit properly
once installed (see figure 3).
Do not install the C-ring
beyond the edge of ceiling tile.

•
Any obstructions above the suspended ceiling that could constrain the orientation
of the suspended subwoofer.
