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

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.

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.
