How to Guide
INSTALLATION GUIDE
Congratulations! You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high delity sound. Our
belief is 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

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 ampliers from 5 to
125 Watts RMS. However, damage to the speakers can be
done by ampliers of nearly any power rating if the amplier
is overdriven into clipping. “Amplier clipping” is a phrase
used to describe a condition when, because of the volume
demand, an amplier 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, but here are some
helpful 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 CL-2 or
CL-3 rated cable may be required. Check local codes. “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
sufcient 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 ensuring the
same wire which is connected to the positive terminal of the
amplier 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 sound quality will be impaired.
