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.

CEILING MOUNT LOUDSPEAKERS

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.

CEILING MOUNT LOUDSPEAKERS

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.
