Speaker Layout

The layout of the speakers should be planned before installation
begins. Layout starts in one corner of the room. The first speaker
should be positioned from each wall a distance approximately equal
to the ceiling height of the room.

The next speaker in row

1 should be spaced a distance approxi-

mately equal to twice the height of the ceiling. Each additional speak­er in the row should use this same spacing.

Row 2 starts at twice the ceiling height distance from row

1 and

twice the ceiling height from the wall. The other speakers in this row
are also spaced at twice the ceiling height.

Row 3 is again spaced at twice the ceiling height from the previous
row. The first speaker starting this row is positioned at one ceiling
height distance from the wall (similar to row 1).

Continue this pattern of alternating rows until the room is covered.

The spacing of the speakers can be adjusted so that the speakers are
evenly spaced in a row and aesthetically pleasing.

TB8 Tile Bridge - The TB8 supports the weight of the
speaker and recessed enclosure. This is also the item to
which the speaker mounting screws attach. The TB8 is
required for each speaker assembly installed.

RE84 Recessed Enclosure - The RE84 is an optional back box
for ceiling speakers. UL Listed for use where ceiling plenum is
part of an air handling system. The RE84 also includes attach­ment tabs allowing the enclosure to be supported from struc­tures other than the actual ceiling grid.

STEP 1 - Remove the tile from ceiling and center the TB8
tile bridge on the back. Use the tile bridge to trace out,
and then cut an 8-1/2” square hole.

NO

TE: It is sometimes more efficient to stack up
a number of ceiling tiles and then cut the speaker
opening in a number of them at once.

STEP 2 - If using the optional RE84 Recessed Enclosure,
bend up the 4 horseshoe tabs (see figure 1 on the TB8).
Position the TB8 over the hole in the tile and push down
the locator tabs (see figure 2).

STEP 3 - Using the 4 supplied screws, attach the CS1EZ
to the TB8 using the 4 clips in the corners of the opening
on the TB8 as nuts.

NO

TE: Only tighten the screws until the grille is
snug against the tile. Over tightening will cause the
screws to dimple the grille.

STEP 4a - If not using RE84 Recessed Enclosure:
Make the electrical connections using the 2 screw terminals
on the CS1EZ. The suggested amplifier connections are:

70V terminal - 70V HOT
COM terminal - 70V COMMON

NO

TE:

The speaker will also work perfectly well with
these connections reversed. However, it is important
to be consistent in the wiring of the speakers in the
system. If adjacent speakers have reversed wiring
connections, they will tend to cancel each other’s bass
response, diminishing the sound quality.

STEP 4b - If using RE84 Recessed Enclosure:
Install an entry fitting to a knock-out in the RE84 to
accommodate the plenum cable. Feed cable through RE84
entry and clamp. Make speaker connections as in 4a. All
connections and any splices must be made within the
enclosure. Place the RE84 over the horseshoe tabs (see
step 2) and twist the tabs with pliers to secure the RE84 to
the TB8.

STEP 5 - Place the assembled ceiling tile back into the
ceiling.
