Mounting Note: The speaker system must be mounted in accordance with local, state,

Rough-in for ES-4T-LE Speaker System
Installation in New Drywall (Sheetrock) Ceiling
On a construction project with a new drywall ceiling where the cable will run in flexible or
fixed conduit, a speaker rough-in bridge and enclosure must be installed before the drywall
ceiling is installed. The ES-4T-LE and ES-62T-LE speaker systems (that do not include
enclosures) are sold separately so that the rough-in bridge and enclosure accessory can be
installed before the drywall ceiling is installed, and the speaker system can then be installed at
a later date after the drywall ceiling is in place and has been painted.

The ES-4-RIB rough-in bridge (sold separately) includes mounting holes on twenty-four
(24) inch centers and sixteen (16) inch centers for mounting to 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.

The same procedure described above would be used to rough in for the ES-62T-LE
speaker system using the ES-6-RIB rough-in bridge and the ES-CP84 enclosure assembled as
shown.

To prepare the rough-in assembly, position the ES-8XD4 enclosure on a work surface with
the bolting holes facing upward. Place the ES-4-RIB bridge on top of the ES-8XD4 enclosure
with the lip facing upward and with the 4 Tinnerman clips on the enclosure lined up with the 4
holes in the bridge. Use the 4) 8-32 X 0.75" bolts (that were supplied with the enclosure) to
attach the bridge to the enclosure as shown.
2 The ES-8XD4 enclosure (sold separately) includes 4) 8-32 X 0.75" bolts.

Mount the ES-4-RIB/ES-8XD4 bridge/enclosure assembly to the ceiling structure with the
lip downward toward the floor. Attach conduit to one or more of the four (4)
combination ½”-¾”
knockouts that are available on the enclosure and install speaker cable as required. When the
ceiling contractor installs the drywall, the lip will be used as a router guide to cut-out the hole in
the ceiling at the location that you have predetermined by mounting the rough-in bridge.
