INSTALLATION GUIDE
Congratulations! You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high delity sound.
The Preference brand is based on the belief that music
matters and we are focused on delivering superlative music
reproduction everywhere in your home.
The following manual is designed to give you, the installer
or owner, basic information as to the speaker’s installation
and operation. It is beyond the scope of this manual to go
into all the details that must be taken into consideration in a
sophisticated high delity system. When installing the wiring
and speakers it is important to adhere to all local codes and
regulations. Consulting a professional can help to maximize
your system’s performance.
If you have any questions regarding this speaker which are
not answered by this manual, contact your local dealer for
assistance. For the most current information please visit:

Wire Cutter / Stripper
Other Possible Tools
Tape Measure, Pencil, Ladder, Drywall Saw, Stud-Finder, etc.
GENERAL DESCRIPTION
These two-way speakers have specially designed woofers
with linear long throw butyl rubber surrounds for long life and
superior damping. Dome tweeters are utilized for excellent
high frequency dispersion throughout your entire listening
environment.
SHIPPING DAMAGE
Each speaker is thoroughly tested before it leaves the
factory. However, in shipment, accidents may occur. Please
inspect your speakers carefully when you receive them to
make sure there is no damage. If there is, please notify your
dealer or supplier immediately for assistance. If you received
your speakers by public transportation, report the damage
immediately to the shipping company.
AMPLIFIER OPERATION
These speakers will perform well with ampliers from 5 to
125 Watts RMS. However, damage to the speakers can be
done by ampliers of nearly any power rating if the amplier is
overdriven into clipping. “Amplier clipping” is a phrase used
to describe a condition when, because of the volume demand,
an amplier is being asked for more power than it can give.
Clipping causes distortion of the audio signal. If you should
hear an unusual amount of distortion at high listening
levels then consider reducing the volume. DAMAGE DONE
TO A SPEAKER BY CLIPPING IS NOT COVERED UNDER THE
WARRANTY.

SPEAKER PLACEMENT
Placement of in-ceiling and in-wall speakers should be
carefully considered. Please contact a professional for
assistance if you are uncomfortable with the planning or
installation process. Ideally, the speakers should be located
where they will provide the best possible sound and ease
of installation. It is beyond the scope of this publication to
discuss all of the various aspects of speaker placement.
However, here are a couple quick suggestions.
For the front channels of a home theater we recommend that
the speakers be placed between 18 and 36 inches (0.45m
to 0.9m) from an adjacent wall/surface, as measured to the
center of the hole. Avoid placing the speakers less than 12
inches (0.3m) from an adjacent wall. When placing speakers
near a corner, avoid locating them an equal distance from the
two adjacent surfaces.
If the drywall has not yet been installed, rough-in-kits are
available to reserve the speaker location. The hole is then cut
when the drywall is installed.
WIRING
To achieve maximum performance we recommend that the
speaker cable be at least 16 gauge or larger for runs over
50 feet (15m) and that the cable be double insulated. A CL2
or CL3 rated cable is usually sufcient. “Zip cord,” which
is single insulated and is often made with clear insulation,
should be avoided as it is not as durable. Allow about 2½
feet (0.8m) of free cable at the speaker cut-out and sufcient
length at the other end to reach the electronics. Having to add
extra cable later can be tedious and time consuming.
Avoid bundling speaker cables parallel to electrical cables
for extended lengths. Though the impedance is low and the
likelihood of interference low, this may help reduce hum and
RF interference. When securing the cable, use care not to
staple or nail through the electrical conductors. Doing so
could result in a short that might damage the electronics.
When connecting your speakers, make sure proper polarity
(phasing) is maintained. Simply put, this means being sure the
same wire which is connected to the positive terminal of the
amplier has its other end connected to the positive terminal
of the speaker. It is important to check this on all speakers. If
the connections on one of the speakers are reversed, (out of
phase) the quality of your bass will be seriously impaired.
INSTALLATION
If the speaker locations have not yet been established then
do so now. If possible, assess the area behind the ceiling
for possible concealed obstructions such as wiring, heating

ducts, cross-bracing etc. Absence of a crawl space will require
greater study of observable clues and may also require the use of
inspection holes and inspection tools (camera, mirror, ashlight,
etc.). Use an “electronic stud nder” to locate the positions of
the joists or studs. We recommend that the edge of the speaker
holes be at least 3/4" (19mm) away from joists or studs whenever
possible to allow clearance for the toggle clamps.
Once the speaker locations are established use the cardboard
template or the plastic compass provided with your speaker to draw
the speaker cut-out. The hole diameters for the various speakers
are marked on the compass. The cardboard templates may also
be used as a visual aid for placement of the speakers. To do this,
temporarily hold the templates in place with a push tack or tape.
Using the proper tool cut the appropriate sized
hole in the ceiling. On drywall, clean cuts can be
made with a drywall saw. Make sure to clean the
excess debris from the front face of the hole to
ensure a ush t.
If the cable has not yet been run, do so now that you have better
access to the ceiling. Once the speaker cable has been run, pull
the end of the cable out of the speaker cut-out, strip back a section
of the jacket as needed, and then expose ½" (13mm) of each
conductor.
To aid in speaker performance, a brous material, such as berglass
or polyester ber, may be placed behind the speaker. This may
also help to reduce unwanted sound from being transmitted into
adjoining rooms. If the ceiling space has blown or loose insulation,
it is important to prevent the insulation from entering the back
of the speaker. This can be accomplished by placing a batt of
berglass insulation, fabric barrier, or bag over the back of the
speaker. Alternatively you may use
an Insu-Flate ISF-147, which is an
acoustically transparent fabric cover
specically designed for this application.
Placing a rigid enclosure behind the
speakers can be done but the enclosure
should be large enough not to degrade
the performance of the speaker. Rigid
enclosures of less than 0.75 cu ft (21 liters) should be stuffed with
acoustic insulation such as berglass.
As the drawing shows, the speakers
utilize Toggle Clamps which, after
tightening, hold the speakers in place.
Ensure that the toggle clamps are
rotated into their “Home” position prior
to installation.
Verify that the speaker ts properly
into the cut-out and then remove the
speaker from the hole.
Connect the wire conductors to the terminals on the back of the
speaker by depressing each spring terminal, inserting the wire
into the hole, and releasing the terminal. Use care to observe the
proper polarity (+ & -). Speakers wired out of phase will exhibit an
apparent loss of bass response.
Note: Single-Point speakers have both the left and right channel
connections on the same speaker. Ensure that both channels are
connected and in phase. An out of phase connection to a single-
point speaker will be immediately obvious when signal is applied
since there will be little if any bass output. If disconnecting one
of the inputs increases the bass output then the inputs are out of
phase.
Insert the speaker into the hole and turn each screw clockwise. The
toggle clamps will rotate outward to engage the ceiling material
as shown. Before tightening the three screws, orient the speaker
toward the listening area. Tighten all the screws.
CAUTION: DO NOT OVER-TIGHTEN THE CLAMPS. Too much torque
may damage the toggle, causing the speaker not to seat securely. A
snug t is all that is necessary to assure proper performance.
The grilles can be painted using multiple light coats of spray paint.
Custom color spray paints are available from specialty companies.
Contact your dealer for more information. The grilles should be
removed from the speaker and painted in a clean environment to
prevent contamination. It is best to go around the grilles and apply
the paint from multiple angles. DO NOT remove the scrim cloth from
the backside of the grille. It is not replaceable.
The mid and high frequency levels can also be adjusted as desired
using the mid frequency (MF) and high frequency (HF) switches.
The MF switch is on the left and the HF switch is on the right, when
looking at the foam surface when the speaker is installed in the
ceiling. Moving the switches to the left decreases the level and to
the right increases the level (See the image above).
Attach the grilles to the speakers and enjoy. Should you wish
to remove the grilles from the speakers pull at the grilles' edge.
Initially there will be signicant resistance because the grilles are
magnetically attached.
