INSTALLATION SAFETY NOTE:
I-MOUNT speaker systems must be installed by a qualified professional installer
in accordance will all local, state, and federal building codes and regulations,
and the installation must conform with industry standard practices. Lowell
recommends that a safety factor of at least X5 be used when designing any
speaker rigging system. It is the responsibility of the installer to consult a
Licensed Structural Engineer to verify the structural integrity and safety of any
mounting method before installation. After installation, inspect the rigging
system regularly and replace worn or damaged rigging components immediately.

Installing in a Drywall Ceiling:
For installation before a drywall ceiling is to be installed, most installers choose to
remove the ¼-20 eyebolts from the rear of the enclosure and use those threaded
inserts to attach the enclosure to Unistrut or other load-rated rigging hardware so it will
span the structure that will support the drywall or other ceiling. Position the enclosure
so that the front lip of the enclosure will be even with or slightly higher than the finished
drywall ceiling when it is installed. Always be sure to leave the protective metal plate in
place so the ceiling installers can’t damage the speaker system’s driver.
The I-MOUNT speaker system enclosures are 23.75" wide so they will fit between the
T-bar supports of a 2' X 2' or a 2' X 4' lay-in tile ceiling. Cut a 14.5" X 14.5" square hole
in the ceiling tile at the center of the desired enclosure location so that the front lip of
the enclosure will fit through the hole and the front lip of the enclosure will be even with
or slightly higher than the face of the ceiling tile as shown in FIGURE 3.
Important Safety Note: Although the speaker system enclosure can lightly rest on the
tile ceiling just to maintain it’s location in relation to the lay-in tile, the entire weight of
the speaker system must be supported by the four (4) load-rated aircraft cables or other
rigging hardware that is attached to the four (4) threaded insert points that are provided
on the rear of the I-MOUNT enclosure. Lowell Manufacturing often gets feedback from
experienced installers who say that their favorite installation method is to use temporary
aircraft cables with adjustable turnbuckles to lower an I-MOUNT speaker system into
place so that exact height adjustments can be made before the four (4) permanent
aircraft cables are installed to support the weight of the speaker system.
Installing in a Lay-In Tile Ceiling:
Installing in an Open Architecture Ceiling:
The I-MOUNT -2SW speaker systems (2 Cu. Ft. Volume) shown in FIGURE 1, and the
I-MOUNT -3SW speaker systems (3 Cu. Ft. Volume) shown in FIGURE 2, are
equipped with four (4) ¼-20 load rated threaded inserts in the rear of the enclosure. As
shipped from the factory, ¼-20 load-rated forged shoulder eyebolts have been provided
in those threaded inserts, which can be used to suspend the enclosure using four (4)
load-rated aircraft cables for an exposed open-architecture ceiling installation.
Protective Metal Plate:
All Lowell Manufacturing I-MOUNT speaker systems are shipped with a protective
metal plate mounted over the speaker driver, so the white front grille is not mounted to
the speaker system when it is shipped from the factory. The installer should leave the
protective plate in place during the installation of the speaker system. After the
speaker system has been permanently installed, remove the protective metal plate and
install the front grille. If it is desired to change the color of the front grille, the grille can
be spray painted before it is mounted to the speaker system. Take care that the spray
paint does not block the round holes in the grille.

The I-MOUNT speaker system enclosures include a rear 4" X 4" cover
plate that allows access to the wiring compartment as shown in Figure 4.
If a transformer is included, it is mounted on a special bracket directly
below the 4" X 4" cover plate. The rear cover plate includes a ½” conduit
knockout which can be removed and replaced with a UL Listed bushing
to protect the speaker cable or a ½” Romex connector as shown in
FIGURE 5. The knock-out can also be replaced with a UL Listed fitting
for flexible conduit if required. The typical cover plate configuration is
shown in FIGURE 7. If solid EMT conduit is required, after the speaker
system has been mounted in its permanent location, a 4" X 4" extension
ring (furnished by the installer) can be used to pipe in and out of the
speaker system enclosure as shown in FIGURE 8.
Transformer Mounting Plate and Rear Cover Plate:
Typical Wiring Method:
Pull the field speaker wiring through the bushing, Romex connector, or
conduit. Connect the field speaker wiring to the two (2) conductors
sticking out of the rear of the speaker system. Red is the positive (+)
lead and black is the negative (-) lead. Use UL Listed wire nuts or crimp
caps as desired to make the splice. Push the splice into the cavity above
the transformer or into the extension ring (if one is used for EMT conduit)
and close the 4" X 4" cover. Note: The splice must be enclosed inside of
the wiring cavity or extrension ring and be enclosed by the 4" X 4" cover
to meet the NEC code.
Setting the Transformer Tap Switch and Mounting the Grille:
Finally, remove the protective metal plate. For models that include a
transformer, set the transformer tap selector switch that is located next to
the driver with a slot-head screwdriver. The tap selections are described
in FIGURE 6 for models with 100 watt or 32 watt transformers.
For 8-ohm models, there is no selector switch provided. Mount the front
grille with the four (4) white screws that are provided.
