LCR Inwall Speakers
SPEAKER PLACEMENT
LCR In-Wall Speakers can be used in any position of a home
theater speaker system. A single LCR In-Wall Speaker can be used
for the front center channel, or a pair can be used for left and
right in the front or rear of the system. Because the LCR In-Wall
Speakers are magnetically shielded, it is safe to place them close
to the television.
Using as a Center Channel Speaker
LCR In-Wall Speakers have been designed to blend seamlessly
with all Proficient wall and ceiling speakers. Install the LCR In-Wall
Speaker horizontally into the wall as close to the screen as possible. This most often means it will need to be installed just above
or below the television. Vertically lining it up with the left and
right speakers while not necessary, will improve the performance.
(Diagram 1)
Using as Front Left and Right Speakers
When using LCR In-Wall Speakers for front left and right speakers, position them vertically with the tweeter towards the screen.
(Diagram 1)
The speakers should be placed so that they form an equilateral
triangle. (D iagr am 2) If the speakers are positioned far away from
the primary listening area, adjust the pivoting tweeters so they are
pointed toward the primary listening area. Note: To avoid possible
damage to the pivoting tweeters, read the section entitled “SPEAKER
ADJUSTMENTS” in this manual prior to performing the tweeter
adjustment.

INSTALLATION CONSIDERATIONS
Before installing your speakers into the wall, you should consider
the placement carefully, taking into account the location of
electrical, plumbing and other fixtures.

If you are not sure of the best location in your particular room
environment, contact your Proficient dealer for assistance.

New Construction - Unfinished Walls
A Pre-Construction Bracket, available from your Proficient dealer,
may be installed prior to drywall application across studs (up to
16" on-center) where a speaker will be located. After the hole is cut
and the drywall is installed, the speakers are then easily installed
following the instructions for mounting in “Finished Walls” below.
Finished Walls
Prior to the actual installation of the speakers, it will be necessary
to run 2-conductor speaker wire to the speaker locations. After the
speaker wire has been properly installed, you are ready to mount
the speakers. Following the simple steps listed below will result in
a professional looking installation:
1. Determine the best area to mount your speakers. This area of
the wall should be free of obstructions such as electrical conduit, HVAC ducts, or water lines. This can best be determined
by noting the placement of fixtures and gaining access to an
attic or crawl space for further analysis of the location of such
obstacles.
2. Find the studs nearest the desired speaker mounting location.
We highly recommend using a good stud-finder tool for this
procedure. If you are lining up the speakers to some other
object or molding in the room, make sure you consider the size
of the baffle flange which extends beyond the mounting hole
on all four sides.
3. Mark the hole. A template for setting the hole is provided in the
box (along with two paint mask inserts for use when painting).
Position the template in the desired position and pencil an outline on the wall.
4. Cutting the hole. CAUTION: This is the most important part
of the entire installation. If you are not certain whether any
obstructions exist behind the desired mounting area, you
should start by cutting a small hole in the center of your penciled mounting hole with a drywall saw. Cut at a 45˚ angle
towards the inside of the hole (Diagram 3). Cutting the small
hole at this angle will make drywall repair much easier as the
piece cut out can be installed neatly back into the hole. Once
you have determined there aren’t any obstructions in your
desired mounting location, start cutting the finished hole at a
90˚ angle to the wall surface.

5. Add insulation. If the area in the wall is not already insulated,
add an adequate amount of insulation material to fill the cavity. If the insulation material used is faced with foil or paper,
position the foil or paper away from the speaker.
SPEAKER INSTALLATION
The integrated six foot mounting system incorporated into each
LCR In-Wall Speaker allows for a quick installation by following
these easy steps:
1. Remove the grille. It may be necessary to push one or two of
the mounting screws and its attached foot towards the baffle
and against the inside surface of the grille to force the grille
out of its retaining groove.
2. Attach the speaker wire (observing the proper polarity with
your amplifier, + to + and – to –). Make sure the left channel
of the amplifier is connected to the left speaker, and the right
channel is connected to the right speaker.
3. Make sure the mounting feet are turned inward to clear the
opening, and insert the speaker into the wall. Position the
speaker into the hole. Note: The flange of the speaker is designed
to flex and conform to any small imperfections in the wall’s surface. Tighten the six screws on the front of the baffle only enough
to make the flange become snug against the wall. As you tighten
the screws, the feet will automatically flip into an outward position
(Diag ram 4), thereby clamping the drywall between the feet and
the flange. CAUTION: Over tightening may torque the baffle,
crack the wall, cause the white bezel to distort, and make the
grille difficult to seat into the grille grooves.
4. Push the grille firmly into the slot in the speaker baffle.

SPEAKER ADJUSTMENTS
Pivoting Tweeter Adjustment
Your LCR In-Wall Speaker comes with the tweeter facing straight
out from the baffle. This will result in the overall smoothest
response. However, depending on your particular primary area,
room acoustics, ceiling height, or personal preference, you may
find the sound more pleasing by pointing the tweeters in a
particular direction. If additional treble is desired in the primary
listening area, point the tweeter towards that area. Push gently
at the edge of the tweeter to point it in the desired direction.
(Diagram 5) CAUTION: Avoid touching the tweeter dome as
damage WILL occur on metal dome tweeters.
For home theater use, we recommend the following tips:
• If the LCR In-Wall Speaker is being used as a main front channel,
the tweeter should be angled towards the listener.
• If the LCR In-Wall Speaker is being used for a rear surround
channel, you may wish to pivot the tweeter away from the
listener to achieve a more diffused sound.
Treble Adjustment:
The switch labeled TREBLE allows for ±3dB of treble adjustment.
Your speakers were shipped with the treble switch in the middle
position, providing the most linear frequency response. If you
desire more treble, move the switch to the “+” position, and the
tweeter will play 3dB higher. If you desire less treble, move the
switch to the “–” position, and the tweeter will play 3dB lower. To
return to the neutral setting, push the switch back to the middle
position. (See Diagram 6)
Bass Adjustment:
The switch labeled BASS allows for ±3dB of bass adjustment. Your
speakers were shipped with the bass set to the middle position.
This setting provides the flattest bass frequency response. If you
desire more bass, push the switch to the “+” position and the bass
will play 3dB higher. If you desire less bass, push the switch to
the “–” position and the bass will play 3dB lower. To return to the
neutral setting, push the switch back to the middle position. (See
Diagram 6)

PAINTING THE SPEAKERS
If you plan to paint your speakers, we recommend that it be
done prior to installation. If you plan to paint your speakers
sometime in the future, it is best to remove them by simply
reversing the steps for “SPEAKER INSTALLATION” on page 2.
If it is necessary to paint the speakers when they are in the
wall, the paint masks provided in the carton must be installed
between the grille and flange while they are being painted
with the wall.
Bass Contour Switch Treble Contour Switch
Before painting your speakers, remove the white acoustic
blanket under the grilles. Once the speaker grille has been
painted, return the acoustic blanket back into place.
Great care should be taken not to clog the holes of the grille,
as this will reduce the sound quality of the speakers.
Proficient recommends only light spray painting using 5 parts
thinning agent to 1 part paint.
