Congratulations!
You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high fidelity sound. We
are constantly striving to provide the very best technology
has to offer.
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 at once 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 more bass we recommend that the speakers be placed
between 18 and 36 inches from an adjacent wall/surface,
as measured to the center of the hole. Avoid placing the
speakers less then 12 inches 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 cut
when the drywall is installed. The cable can be tied off on
the rough-in-kit after securing it to a nearby joist.
WIRING
To achieve maximum performance from your new speakers
we strongly suggest the use of good quality stereo cable. We
recommend that the cable be at least 16 gauge or larger for
runs of over 50 feet and that the cable be double insulated.
This is often referred to as “jacketed” speaker cable and
CL-2 or CL-3 rated. “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 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
