PRODUCT DESCRIPTION
Concourse C models are complete assemblies
ready for installation into both suspended tile
ceilings and hard ceilings. A rear mounted termi-
nal box allows termination of the speaker wiring
to the speaker as well as impedance selection
(except C4T and C4-16). Power taps are selected
on 70/100V versions through a front mounted
rotary switch.
Speakers are mounted by means of four mounting
clamps located around the rear face of the bezel.
A metal split C ring is provided to distribute the
clamping pressure evenly along the ceiling sur-
face. A pair of metal mounting support rails are
provided for added support when the speakers
are installed in a suspended tile ceiling.
A seismic restraint point is provided on the rear of
the speaker to facilitate attachment of a restraint
tether to the building’s structure. The removable
front grille is also fitted with a restraint tether that
attaches to the inside of the bezel by means of a
supplied insert.

INSTALLATION
Suspended Tile Ceilings
Step 1
Carefully unpack the contents of the box and ensure that all parts
are accounted for before beginning installation.
Step 2
Remove the tile from the ceiling and place it on a suitable work
surface to cut the hole and assemble the speaker. Locate the
cardboard mounting template and use it to mark the hole size
needed for the installation. Center the template on the ceiling tile
and cut the hole using a suitable saw, or knife.
Step 3
Once the hole is cut, rest the speaker face-down on the work
surface and place the cut ceiling tile over top of the assembly,
ensuring the tile is resting on the speaker bezel.
Step 4
Place the mounting rails on the ceiling tile on either side of the
speaker assembly ensuring that they are oriented correctly to
provide support by resting on the tile mounting grid when installed
in the ceiling
Step 5
Place the C ring over top of the speaker assembly and align it with
the mounting rails. Using the supplied screws, fasten the C ring to
the mounting rails.
Step 6
Lift the assembly to gain access to the front of the speaker, then
using a screwdriver tighten each of the four mounting screws in
sequence. Turning the screws in a clockwise direction will cause
the mounting clamps to rotate into position then extend down to
clamp the assembly to the ceiling tile.

Step 7
Remove the screws holding the terminal cover plate and then
remove any knock outs needed to connect the speaker wiring.
Step 8
Select the appropriate impedance using the push-button switch
inside the terminal box if the speaker is part of a low impedance
system (except C4T and C4-16).
Step 9
Lift the entire assembly to the ceiling and terminate the wiring to
the terminal strip. Replace the cover plate and screws.
Step 10
Place the assembled speaker and ceiling tile into the ceiling grid,
ensuring that the mounting rails are resting correctly on the grid.
Step 11
Set the correct wattage tap (except C4-16) using the front mounted
rotary power switch. NOTE: The switch is labeled for both 70V
and 100V power taps; ensure you select the correct tap for the
connected amplifier.
Step 12
If the speaker bezel is to be painted, place the supplied clear plas-
tic paint cover over the front. Otherwise, attach the grille restraint
tether by inserting the plastic plug into the hole on the inside of
the bezel and then seat the grille to the bezel by pushing firmly
around the perimeter of the grille.

INSTALLATION
Hard Ceilings
NOTE: Installation into a hard ceiling requires that you first
ensure that the location is suitable and that there are no obstacles
behind the ceiling material. Use EXTREME CAUTION when cutting
into hard ceilings to avoid severing electrical wiring, heating ducts
or water pipes.
Step 1
Carefully unpack the contents of the box and ensure that all parts
are accounted for before beginning installation.
Step 2
Locate the cardboard mounting template and use it to mark the
hole size needed for the installation. Cut the mounting hole using a
suitable saw.
Step 3
Once the hole is cut, insert the split C ring by twisting slightly and
rotating it into the hole. Center the C ring around the opening.
Step 4
Remove the screws holding the terminal cover plate and then
remove any knock outs needed to connect the speaker wiring.
Step 5
Select the appropriate impedance using the push-button switch
inside the terminal box if the speaker is part of a low impedance
system (except C4T and C4-16).
Step 6
Lift the speaker to the ceiling and terminate the wiring to the
terminal strip. Replace the cover plate and screws.
