INSTALLATION CONSIDERATIONS (CONTINUED)
NOTE: BE VERY CAREFUL WHEN LOCATING THE SPEAKERS. VERIFY ALL LOCATIONS
ARE CLEAR OF OBSTRUCTIONS BEFORE CUTTING THE FIRST HOLE.
Each speaker requires two-conductor wiring of sufficient gauge. The gauge depends
on the length of the wire. For recommendations, please refer to (Figure 2). (Stereo
Input loudspeakers require four-conductor wiring).
When running loudspeaker wire inside walls or ceilings, use special jacketed
cable (CL-2 or CL-3 rating) to protect the wire and for fire prevention. In some
municipalities, conduit is required. For a trouble-free installation, low voltage wire
such as loudspeaker wire must be in accordance with the National Electrical Code
and any applicable provisions of the local building code. If you are unsure of the
correct installation techniques, wire jacket, or type of conduit to use, consult a
professional audio/video installer, building contractor, or the local building and
inspection department.

INSTALLING THE LOUDSPEAKERS
It is often easier to lay the speakers out on the floor and then transfer the locations to
the ceiling with a laser plumb bob. If you are using new construction brackets, place
string across the centers of the bracket to provide a way to align the bracket to the
laser. Remember, you will need 1” to the sides of the mounting hole for the mounting
clamps to secure the speaker to the drywall.
1. Once you have determined a possible position for the hole cutout, drill a 1/8”
pilot hole just barely through the ceiling (1/2” to 5/8” deep in most homes) in
the center of your proposed loudspeaker location. BE VERY CAREFUL NOT
TO DRILL THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF
YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE DRILLING, STOP.
2. Cut a foot-long piece of coat hanger. Bend the wire (creating a right angle)
leaving 5-1/2” at one end (this allows for the extra width of the mounting dogs).
Poke the “L-shaped” wire into the pilot hole and turn it in a complete circle and
move it into the ceiling cavity to make sure you have approximately 8” of depth.
If the wire’s movement is obstructed by anything, fill the hole(s) with spackle
and try another location (If there is any risk of unisulated electrical connections
within the ceiling area, use insulating gloves or other materials or consult with an
installation professional before proceeding).
3. If the coat hanger moves freely in a complete circle and you have sufficient
depth, tape the template to the ceiling and proceed to layout the other speakers.
Once you are comfortable with all speaker locations, use a pencil to lightly
outline the circular template.
4. Drill the starting point of your cut with a 1/4” bit.
5. If you are cutting drywall, use a sheetrock or keyhole saw. Cut the hole with the
saw at a 45° angle. That way the drywall section can be replaced cleanly if there
is an unseen obstruction behind the wall. IMPORTANT: BE VERY CAREFUL
NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE.
IF YOU FEEL EXTRA RESISTANCE AS YOU ARE CUTTING, STOP.
NOTE: DO NOT INSTALL LOUDSPEAKERS BEFORE THE DRYWALL HAS BEEN COM-
PLETELY FINISHED AND PAINTED.
6. Prep the speaker wire by stripping 1/4”-1/2” from each speaker lead. Twist the
strands or tin the leads with solder to ensure there are no stray strands that could
short and possibly harm the amplifier.

INSTALLING THE LOUDSPEAKERS (CONTINUED)
7. The speaker has black and red
spring-loaded connectors attached
to the Rear Wave Control enclosure
(Figure 3). Black is for the negative
(–) wire and red for the positive (+). It
is important to observe correct wiring
polarity. This is especially important
for the Stereo Input (SI) Loudspeaker.
If you have wire other than black and
red, make sure you connect it the same
on the amplifier end as the speaker
end. Failure to do so will adversely
affect the loudspeakers’ performance.
Supports are provided to secure the
speaker wire with wire ties.
8. A safety wire anchor is provided on
the Rear Wave Control enclosure
should you be required to secure the
loudspeaker assembly to a roof beam
or rafter (Figure 4).
9. Once the speaker wires and safety
wire are connected, carefully slide the
loudspeaker with attached Rear Wave
Control enclosure into the opening hole
(Figure 5). While holding the speaker
in place, tighten the mounting
screws to secure the speaker to
the drywall. We recommend
using a motorized screwdriver.
Be careful not to over tighten.
ICS loudspeakers feature spring
loaded mounting clamps that
allow the speaker to remain
flush with the ceiling, even if the
drywall shifts or expands.
NOTE: DO NOT CARRY THE SPEAKER
BY THE TWEETER OR TWEETER BRIDGE.
THIS MAY DAMAGE THE SPEAKER.

ADJUSTING THE PIVOTING WOOFER AND TWEETER
ICS loudspeakers feature the patented Directed Soundfield™ woofer pivot
mechanism that enables the loudspeaker to direct the sound to the listening area
(Figure 6). The tweeter(s) pivot independently of the woofer to provide additional
control of the sound. Adjusting the woofer angle will affect the tweeter angle, so
always begin by adjusting the woofer.
The ability to control the front sound wave via Directed Soundfield and the rear
sound wave via the Rear Wave Control enclosure gives ICS loudspeaker powerful
advantages over competitive models.
1. Press the outside edge of the woofer on the plastic, not the rubber, and slide
the speaker until it is facing the primary listening position. The woofer adjusts
approximately 15-degrees. Do not force the speaker to move beyond its limits.
2. After adjusting the woofer, adjust the tweeter by pressing on the outside edge of
the tweeter until it is facing the primary listening position.

SETTINGS ADJUSTMENTS
TWEETER SWITCH (RWC7.3, RWC7.5, RWC8.5, RWC7.7, RWC8.7)
The three-position tweeter switch allows you to adjust the high frequency output of
the loudspeaker to compensate for environmental issues. The center position does
not affect the tweeter output. Moving the switch to the – position reduces the tweeter
output by 3dB to compensate for bright rooms (tile or wood floors, spare furnishing,
tall ceilings). Moving the switch to the + position increases the tweeter output by 3dB
to compensate for absorptive rooms (carpeting, lots of drapery, plush furniture, etc.).
DIALOG COMPENSATION SWITCH (RWC7.3, RWC7.5, RWC8.5,
RWC7.7, RWC8.7)
This switch provides additional definition at critical midrange frequencies where
the human voice is reproduced. This switch is generally used only for home theater
center speaker applications. Engage the switch if you wish to enhance the dialog.
DIFFUSE / DIRECT SWITCH (RWC7FX, RWC8FX)
Use the Diffuse setting for movies and general music listening since most films are
mixed using non-localized surround effects and music is usually recorded in a
favorable acoustic environment. Use the Direct setting for discrete multi-channel
recordings that equally emphasize front and surround sounds. For 7.1-channel
surround sound systems, use the Diffuse setting on the side effects loudspeakers and
the Direct setting for the rear effects loudspeakers.
PAINTING THE GRILLES
ICS loudspeaker grilles can be painted without priming, but the fabric scrim must
first be removed. The installation template has die cut standoffs that can be used to
position the grille off the ground while painting. Use several light coats sprayed from
different sides and angles to cover all surfaces and not fill in any holes. If you do
fill some holes, use compressed air to open them before the paint dries. It may be
helpful to dilute the paint.
INSTALLING THE GRILLES
The ICS MicroThin™ speaker grille installs magnetically over the speaker. Carefully
center the grill over the speaker and let the magnets do their work, verifying that the
grill sets flush against the ceiling at all edges.
