MECHANICAL INSTALLATION 110TB
2’ x 2’ Tile Grid Installation Procedures:
1) The 110TB was designed for quick and simple installation directly into a 2’ x 2’ T-bar ceiling grid (Figs. 9 & 10).
2) Remove several tiles around the installation location to gain easier access for lacing the subwoofer in the ceiling
grid.
3) Be certain that there is sufficient hanger wire suspending the grid where you intended to install the subwoofer.
If not, it may be necessary to add additional grid hanger wires around the perimeter of the location, as required.
We recommend a minimum of four per sub location located on the main grid support bar within four inches of each
of the four corners of the subwoofer.
4) Using wire rope or chain, select opposing corners on the subwoofer to connect safety lines, or seismic tethers
(Figs. 8 & 9) securely to the structure. These lines should be taut enough to support the majority of the weight of
the 110TB, yet leave enough load against the ceiling grid to prevent the grid from buzzing. Be sure all tether points
are securely fastened to the subwoofer and achored securely to the substructure of the building.
Free Space Installation Procedures
1) For an installation in free space, select a location that will allow suspension from directly above the subwoofer.
Begin by measuring a 19-1/2” square, and at each corner, install a fastener (Fig. 11 & 12) such as the
recommended hanger bolt to support each corner of the subwoofer.
2) Thread a coupling nut all the way over a hanger bolt, and with a 9/16” socket set, start threading the hanger bolt
into the support structure. Secure a hanger to a substructure at all four corners. This may be accomplished several
ways depending on your particular installation.
