EMPHASYS
Dual Channel In-Ceiling
Speakers from EMPHASYS are de-
signed to deliver crisp, full-range sound
for today’s home theater and distrib-
uted audio environments, where digital
media places extreme demands on a
speaker’s capability. But while ordinary
speakers must be used in matching pairs
for correct stereo reproduction, the
Dual Channel In-Ceiling Series models
deliver awesome stereo sound from a
single speaker. EMPHASYS engineering
has combined a dual voice coil woofer
with twin tweeters, and as a result the
Dual Channel In-Ceiling models bring
high-quality stereo audio to even the
smallest room.
DC8.5 DC6.0
Positioning the Speakers
It is best, with the Dual Channel
In-Ceiling Speaker or any other
unit, to position it so that it
aims directly toward the
listening position. This
will ensure an accurate
stereo image and
help minimize the
creation of excessive
sound reflections.
If the listening room is
very large or the ceiling
is high, the DC8.5 — with its
8" aluminum woofer and greater
power handling — will be preferable
to the DC6.0.
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 obstruc-
tions 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)
You can use the cutout piece to fill the hole again if obstructions
are found. 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 touch-
ing 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.
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 Dual Channel In-Ceiling 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" on-
center) where a speaker will be located. After the hole is cut and
the drywall is installed, the speaker can be easily installed follow-
ing 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.
Finished Ceiling
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 professional-
looking 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 studs 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
Dual Channel In-Ceiling speaker.
Speaker Adjustments
Creating a Zone for Optimized Listening
The Dual Channel In-Ceiling 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 of the DC8.5 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.

Painting the Grille
We recommend painting your grille prior to installation. If you
decide to paint it in the future, it is best to remove the grille by
simply detaching it from the speaker. Do not paint the grille while
it's installed on the speaker.
Before painting, be sure to remove the cloth material from
beneath the grille. Once painted, place the cloth back to its
position beneath the grille.
When painting, be careful not to clog the holes of the grille. The
sound of the speaker will be dramatically reduced if the perfora-
tions in the grille are covered in paint.
EMPHASYS recommends only light spray painting using five parts
thinning agent to one part paint.
Treble Adjustment
The Treble switch allows +3dB of adjustment from the “0” position,
where the most linear frequency response is maintained. If more
treble is desired, simply move the switch to the “+3” position. To
return to the neutral setting, move the switch back to the “0”
position. The Treble switch can be adjusted whenever desired.
(See Diagram 4)
Bass Adjustment
The Bass switch provides +3dB of bass adjustment from the “0”
position, where the flattest bass frequency response is maintained.
For extra bass, move the switch to the “+3” position. To return to
the neutral setting, move the switch back to the “0” position. As
with treble adjustment, the Bass switch can be moved whenever
desired. (See Diagram 4)

CAUTION: Excessive tightening may torque the baffle, crack the
ceiling or cause difficulty in aligning the grille.
4. Reattach the grille onto the speaker baffle.
Installing the Speakers
Dual Channel In-Ceiling Speakers feature a mounting system with
four swiveling feet for quick, secure installation. Use the following
steps:
1. Remove the grille from the speaker baffle.
2. Attach the speaker wire (observing the proper polarity with
your amplifier, matching positive (red) to positive and negative
(black) to negative). Either channel may be attached to either
terminal set, however, be sure that polarity (+ and -) is correct on
each channel or the performance of the speaker will be seriously
affected, as one channel will cancel out the other.
3. Be sure the mounting feet are turned inward to clear the
opening, and then insert the speaker into the ceiling. Position the
speaker into the hole. Note: The speaker is designed to conform to
minor imperfections in the ceiling’s surface. Tighten the four screws
on the front of the baffle only so much that the speaker becomes
snug against the ceiling. As you tighten the screws, the feet will
flip into an outward position clamping the drywall (see Diagram 3),
between the feet and the speaker.
