Run the cable through the metal clamp strain relief and make the wiring terminations on the
plug-in connector. Plug the connector back in on the rear of the speaker, tighten the metal
strain relief clamp, and close the wiring cover.
NOTE: Lowell Manufacturing recommends that a suitable safety cable be attached from
the ring that is supplied on the rear of the speaker enclosure to the building structure. In
some areas of the country,
building codes require this type of “safety cable” or
“earthquake cable”. Refer to applicable building codes for safety cable requirements.

6 Using a Phillips screwdriver, open the screw on the wiring cover on the rear of the
speaker, slide open the cover, and remove the plug-in connector. Two (2)
parallel “-“ terminals
and two (2) parallel “+” terminals are available for input wiring to the speaker and for output
wiring to the next speaker in the string. The wiring schematic for a typical 25V, 70V, or 100V
speaker system is shown in the diagram below:

For use in a speaker system without using the internal matching transformer, one cable should
run from the output of an 8 ohm maximum 25 watt amplifier to one ES-4T speaker only, or from
the output a 4 ohm maximum 50 watt amplifier to one ES-62T speaker only. Wiring the speaker
system in a series/parallel configuration may be acceptable depending upon the amplifier used,
but that wiring method is not covered in this installation manual.
9 Use the plastic shipping cover as a paint shield and spray paint the front trim ring.

Using a flat blade screwdriver, set the transformer tap select switch on the desired position
(see the tap chart on the face of the speaker). Note: Do not use an 8
W
or 4
W
switch
position when using the speaker level output from a 25V, 70V, or 100V amplifier.

Carefully peel off the white scrim material before painting the grille. Spray paint the grille
with a few light coats being very careful not to clog the holes in the grille with paint. After the
paint on the grille is dry, replace the scrim using a light coat of all-purpose spray adhesive.

Note: If custom paint is not required, skip to step . 11
Press on the front grille until it is flush with the trim ring and the installation is complete. 11
For a tile ceiling installation the speaker is mounted to the tile and C-ring/rail assembly before
the wiring is terminated (as was already described in step ). At this point, place the
speaker/tile/C-ring assembly on the ceiling grid.

For a drywall ceiling installation, push the rear of the speaker through the hole in the
ceiling making sure that the mounting ears line up with the C-ring (and not with the gap in the
C-ring). Tighten the mounting ear screws with a Phillips screw driver so the ears rotate away
from the speaker body and clamp the speaker to the ceiling and the C-ring. WARNING: 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 up to 2.125".
