Congratulations!
You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high fidelity 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 fidelity 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:

MINIMUM TOOLS REQUIRED
# 2 Phillips Head Screw Driver / Drill Driver
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 amplifiers from 5 to
125 Watts RMS. However, damage to the speakers can be
done by amplifiers of nearly any power rating if the amplifier is
overdriven into clipping. “Amplifier clipping” is a phrase used
to describe a condition when, because of the volume demand,
an amplifier 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 sufficient. “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 sufficient
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
amplifier 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
