PLACEMENT OPTIONS
Polk Audio LCj Series In-Wall Loudspeakers
give you nearly endless placement options.
But remember that placement choice for your
in-wall speakers bears careful consideration,
as installation requires that you cut a hole in
your wall or ceiling!
Fill a room with sound by installing in-wall
speakers in nearly any wall or ceiling
location [figure 1]. Polk LCj Series In-Wall
Loudspeakers have a wide dispersion pattern
and aimable tweeters that allow you to focus
their sound.

ADJUSTING THE TWEETER
Aiming the tweeter toward your listening
position improves imaging and detail. When
using LCj Series In-Wall Loudspeakers as
front/main home theater speakers [figure 2],
aim the tweeter toward your listening posi-
tion. For rear/surround speakers installed in
walls or ceilings [figure 3], aim the tweeter
toward the nearest reflecting surface (an
adjacent wall or ceiling) for a more diffuse
sound field (if you so desire; for more
direct sound, aim the tweeters at your
listening position).

PERFORMANCE ENCLOSURES
Are available for all models. These are engi-
neered enclosures that mount in the wall or
ceiling to maximize the bass and midrange
performance of your LCj Speakers. They are
typically installed prior to drywalling in new
construction, but can be retrofitted if desired.
Note: LCj Series In-Wall Loudspeakers are
not magnetically shielded and should not
be placed closer than l' (30cm) from a
direct view television or video monitor.
If you experience discoloration or distortion,
immediately move the speakers away from
your TV.

DIRECTING THE DRIVER (LCi60 & LCi 80)
The fixed 15° angled driver in the ceiling
speaker allows you to direct the midrange
towards your listening area when used for
front stage (l~ft-center-right). When used as
rear surrounds or 6.1 or 7.1 back speakers,
direct the driver towards the listening area
for a more direct sound field or toward a
wall for a more diffuse soundfield.

MAKING ADJUSTMENTS
The LCi Series features technology that can
tailor the sound for performance in difficult
or unusual placement situtations.
LC265i, LC65i, LC80i & LC60i MODEL
ADJUSTMENTS:
Wall Distance Toggle -In-wall loud-
speakers excel when placed'more than 2'
(60cm) from side walls. If position limitations
demand that in-wall loudspeakers be installed
closer than 2'(60cm) from side walls, the
proximity of the surface can result in a
response "bump" between 50 and 200Hz.
This can cause in-wall speakers to sound
"boomy." The Distance Toggle Switch flattens
response and tunes out "boominess" without
sacrificing
deep bass response, for more life-
like sound.
Recommended speaker
distance
from side walls
is 2 feet (60cm).

-3dB 1\veeter Attenuation -If your lis-
tening room is very reflective, with smooth
sheetrock walls, hardwood floors, and
non-cushioned furniture, the sound will be
overly "bright" and unnatural.
Engaging the LCi Tweeter Attenuation feature
(by selecting the "Cut" setting) compensates
for the effect of reflectivity in a hard room.
Tweeter Attenuation flattens room response
without hindering higher frequency response,
for warmer, more
realistic sound and more accurate imaging.

LC801 & LC601 MODEL ADJUSTMENTS:
Area Targeting - Round LCi models fea-
ture a swiveling Ring Radiator 'I\veeter speak-
er for better directionality. The "sweet spot"
is within a 30° cone of sound coming from
the aimed speaker. The round model LCi
Loudspeakers feature an innovative Area
Targeting Switch. Engaging this function
"expands" the area of high frequency
response, improving off-axis imaging
and filling the room with well-balanced,
high performance sound.

PAINTING YOUR Lei SERIES IN-WALL
LOUDSPEAKERS
You will need:
• Paint of your choice (to make the job easi-
er, we recommend spray painting the grille)
• A
paperclip or corkscrew (for removing the
paintable grille, corkscrew can also be used
to open the wine when you relax with your
newly painted Lei speakers, see page 10).
• Masking tape
• Paint mask (to cover unpaintable
parts, suppJied.0

PREPARING TO PAINT:
1. Separate the parts of the speaker. If the
speaker is not yet installed, the grille can
be removed simply by pushing the clamp
screws forward to push the grille off the
speaker from the inside. If the speaker is
already in the wall, carefully hook the
grille with a bent paper clip and pull it
gently away from the frame [figure 7].
2. Remove the cloth scrim from the inside of
the grille. Replace after paint dries.
3. When painting the frame of the speaker,
use the supplied paint masks to carefully
mask off the front of the speakers to pro-
tect the drivers and baffles while painting.
You can do this while the speaker is
already installed in the wall (if, for
instance, you're repainting the room). If
you do not have the paint masl<s, carefully
mask the speaker components using paper
and masking tape.

PAINTING THE FRAME:
1. Apply paint to exposed (unmasked parts).
Use two or more thin coats. Spray painting
is recommended [figure 8].
2. When the paint is completely dry, remove
the masking material.
PAINTING THE GRILLE:
1. The grille of the LCj Series speaker fea-
tures an even, protective paint. This paint
is an ideal primer.
2. Grilles must be spray painted. Do not use
abrush and paint. Thick, brushed paint
may clog the grille holes.
3. After removing the grille by carefully hook-
ing it with a bent paper clip and pulling it
gently away from the frame, spray on two
thin coats of finish color. If you're using a
compressor
and spray gun, use the finest,
most diffuse setting. Be careful not to fill
the holes in the grille with paint [figure 9].
4. When the paint is completely dry, carefully
reinstall the grille by fitting it into its
recess so that it is just resting on the
frame. Starting with one corner, go around
the speaker and push the grille into the
grille notch alittle bit at a time. Be gentle;
the grille may be easily bent out of shape
by rough handling. You will feel a positive
"snap" when it is fully in place.

INSTALLATION
Out of the box and into the wall, that's how
easy it is to install Polk Lei Series In-Wall
Loudspeakers.
If you intend to do the installation yourself
we recommend that you possess some skill
in the proper use of hand and power tools.
You should have a thorough understanding of
local building and fire codes and afamiliarity
with
the area behind the wall or ceiling into
which you plan to install your speakers.
Install speaker wires before installing speak-
ers. Wire meeting appropriate building and
fire codes must be used. Use at least 18
gauge wire or heavier for the utmost in sound
quality. Wiring is best performed by an expe-
rienced professional. If you are in doubt that
you possess the necessary skills or tools,
consult your Polk Audio dealer, or a profes-
sional installer.

FOLLOW THESE EASY STEPS:
• Make sure the material into which you plan
to mount the speakers (plaster, drywall,
paneling, stone, etc.) can support the
weight of the speakers (see specification
page for the weight of your model).
• Make sure the locations you select do not
conceal studs, electrical wiring or plumb-
ing. Prior to installation, hold the speaker
in your chosen location to make sure it
safely clears obstacles such as studs, cor-
ners, beams, lighting fixtures and door/win-
dow frames. Your cutout must be at least
1" (25mm) from adjoining walls or ceiling,
internal studs or plumbing.
• Using the template, trace the installation
location with a pencil. You can do this by
holding the template in your preferred
location and tracing around it. Use a level
to make certain the template is straight and
plumb. This is the exact cutout size.
[figures lOa &lOb]
•
Carefully cut the hole with the appropriate
cutting tool for your wall or ceiling material.
Start
the hole by drilling a hole on the inside
of the tracing (with the drill bit touching the
line). Use this hole to insert the saw or knife
and begin cu tting [figure 11].
•
Once you have cut the hole, fish your previ-
ously positioned wiring out of the hole and
connect the speaker. Follow the hookup
directions included with your receiver. Strip
Ih inch (12 mm) of insulation from each of
the two conductors of the wire to expose
the bare metal and twist each of the con-
ductors into a single unfrayed strand (so
you have two unfrayed strands). Note that
one of the terminals on the rear of each
speaker is red (+) and the other is black
(-). Make certain that you connect the wire
from the red terminal (+) of your amplifier
or receiver to the red terminal (+) on your
speaker and the wire from the black termi-
nal (-) of your amplifier or receiver to the
black terminal (-) on your speaker. Most
wire has some indicator (such as color-
coding, ribbing or writing) on one of the
two conductors to help you maintain
consistency [figure 12].

• To install the speaker, first carefully remove
the grille using astraightened paperclip or
other pointed metal tool. Insert the point
into one of the grille perforations near a
corner
and lift the grille free. Never use
a knife or screwdriver to pry between the
grille and the speaker frame. This will
damage your speaker.
• Loosen the rotating wall clamps by
unscrewing them. Make sure that the
rotating wall clamps are flipped inwards
so that your speaker fits into your cutout
without nicking your wall. Then place the
speaker carefully into the cutout [figure
13]. If you have a level, use it to help you
correctly align the speaker. Tighten the
wall clamp screws with a screwdriver. This
will rotate the wall clamps and secure the
speaker to the wall. Hint-on the LC265j
and LC65i models, tighten the center
screws before tightening the corners for
the most flush fit to your wall. Do not over-
tighten the wall clamp screws [figure 14].
