Remove the 2' X 2' or 2' X 4' ceiling tile. Place the tile face down on a soft surface (to
avoid damaging the surface of the ceiling tile). Assemble the C-ring and rails assembly by
using 1 screw to attach each rail to the C-ring in the desired location. Place the assembly on
the rear of the tile so that it spans the 2' width of the tile. Trace the inside edge of the C-ring as
shown. The C-ring/rail assembly can be rotated 180 degrees to complete tracing the circle
where the ring has a gap. Use a hole saw to cut out the hole in the ceiling tile.

Use a saw to cut the hole. For a drywall ceiling, the support rails provided need not be

but it is recommended that the “C ring” be used to support the cut-out edge of the drywall.

The gap in the C-ring allows the ring to be maneuvered into position as shown.


When installing the ES-4T or ES-62T in an existing drywall ceiling, it is important before
cutting the hole, to confirm that there are no obstructions above the drywall ceiling that would
prevent the speaker from being installed at your chosen location. Once the location has been
chosen and it has been determined that no obstructions exist, use the cardboard template
provided to trace the cut-out circle on the ceiling.



Insert the rear of the speaker through the hole in the tile. Tighten the mounting ears with a
Phillips screw driver so that the ears rotate away from the speaker body and trap the tile
between the speaker and C-ring/rails assembly. Do not over-tighten the mounting ear
screws or the plastic ears can break.
As shipped from the factory, the mounting ears can
span a ceiling thickness of 1.25". The ears can be removed, rotated 180 degrees, and placed
back on the tightening screws and they will then be capable of attaching to a ceiling thickness
of up to 2.125". Most contractors prefer to wire the speaker before placing the tile/speaker
assembly on the ceiling tile grid. Skip to for speaker wiring.

On a new construction project, it is best to install a rough-in bridge before the drywall
ceiling is installed. The ES-4-RIB rough-in bridge (sold separately for use with the ES-4T) and
the ES-6-RIB rough-in bridge (sold separately for use with the ES-62T) are available for this
purpose. Holes are provided on the bridge on twenty-four (24) inch centers and sixteen (16)
inch centers for mounting to the bottom of the joists, rafters, trusses, metal rails or other ceiling
support structure. Screw types required to mount the bridge vary widely depending on the
construction of the ceiling structure so mounting screws are not included and will be
supplied by the installer.
Mount the bridge with the lip facing downward toward the floor.
When the ceiling contractor installs the drywall, the lip will be used as a router guide to cut the
hole in the ceiling that is required to install the speaker. Skip to for speaker wiring.
