In-Ceiling LCR Speakers
from EMPHASYS have been created to
meet the needs of today’s discriminating
listener, offering a blend of clarity and
output that’s equal to the needs of a
high-performance home theater or
distributed audio system. In fact,
an EMPHASYS In-Ceiling LCR can
be just as appropriate as the center
channel speaker as it is in a left/right
pairing. The In-Ceiling LCR Series
really delivers, with superb components
and great sound in a range of sizes. This
manual is designed to facilitate easy
installation and adjustment of the
EMPHASYS In-Ceiling LCR Speakers.
To ensure the best performance, please
Positioning the Speakers
EMPHASYS In-Ceiling LCR Speakers,
with their superior clarity and power
handling, provide exceptional versatility
for the home theater environment. A
single LCR 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.
The In-Ceiling LCR Speaker as a Center Channel
In-Ceiling LCR Speakers are designed to blend seamlessly with other EMPHASYS speak-
ers and accessories, and will satisfy almost any installation. However, if the LCR is to be
used as a center channel speaker, it should be placed directly above the TV. Additionally,
system performance can be enhanced if the center channel speaker is aligned as closely
follow the instructions carefully.
as possible with the horizontal plane of the front left and right speakers.

Creating a Zone for Optimized Listening
The In-Ceiling LCR speakers should be placed so that they project,
as much as possible, toward the listening position. This will ensure
an accurate stereo image and help minimize the creation of
excessive sound reflections.
If the speakers are to be mounted in a very high ceiling, the
pivoting tweeters should be aimed directly toward the listening
position. (See Diagram 1)
In other cases it might be preferable to aim the tweeters slightly
outward, away from the listening position.
CAUTION: The tweeter dome, whether aluminum or silk, can be
damaged through direct contact with fingers or objects. Please be
careful when installing and adjusting the speaker.
Preparing the Surface for Mounting
Precautions for Installation
Careful consideration should be given to the possible presence
of electrical conduits, piping, HVAC duct work and other ele-
ments in the ceiling before the In-Ceiling LCR speaker is installed.
If there is any doubt regarding the most acceptable locations for
the speakers, please consult EMPHASYS Technical Support or the
dealer.
New Construction: Unfinished Ceiling
A new construction bracket, available from your dealer, can be
installed prior to drywall application across joists (up to 24" oncenter) where a speaker will be located. After the hole is cut and
the drywall is installed, the speaker can be easily installed following the instructions for mounting in “Finished Ceiling” below.
Note: If the speaker is to be mounted more than 24" on-center, a
special “extra-long wing” is available from your dealer.

3. Mark the hole. A template for setting the hole is provided in
the box. Position the template in the desired position and outline
it on the ceiling using a pencil.
4. Cut the hole. CAUTION: This is the most important part of the
installation.
If you aren’t certain whether there are any obstructions in the desired mounting area, use a drywall saw to cut a
small hole at the center of the spot you’ve outlined. Cut at a 45°
angle toward the inside of the hole. (see Diagram 2)

Prior to the actual installation of the speakers, it will be necessary
to run speaker wire to the locations in which they’ll be mounted.
See your dealer for more information. Then, with the wire in
place, the speakers can be mounted. To ensure a professionallooking result, follow the simple steps described below:
1. Choose the general location for the installation of each speaker, being certain that these areas present no obstructions such as
electrical conduit, HVAC duct work or water lines.
2. Find the joists nearest the desired location for the speaker.
EMPHASYS recommends the use of a good stud finder for this
procedure. If you are lining up the speakers to some other object
or molding in the room, be sure to allow for the size of the baffle,
which extends beyond the mounting hole on all four sides of the
In-Ceiling LCR Speaker.
You can use the cutout piece to fill the hole again if obstructions are
encountered. Once the mounting location is deemed to be free
of obstructions, cut the outline at a 90° angle relative to the surface of the ceiling.
5. If the area in the ceiling isn’t already insulated, add insulation
material sufficient to fill the cavity. If the insulation material used is
faced with foil or paper, position the foil or paper away from the
speaker.
CAUTION: Speaker components can get hot while playing music at
moderate to high volume levels. There should be nothing at all touching the speaker. Material in proximity to the back of the speaker must
have at a minimum 1” or 26mm clearance for non-flammable materials
and more for flammable materials like plastic vapor barriers.
