Congratulations!
You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic equipment,
expect years of quality high fidelity 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 fidelity system.
When installing the wiring and speakers it is important to adhere to
all local codes and regulations. Consulting a professional will help to
maximize your system’s performance.
If you have any questions that 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. Pivoting 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-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 more bass, place the speakers between 18 and 36 inches from
an adjacent wall as measured to the center of the speaker. Avoid
placing the speakers less then 18 inches from an adjacent wall. When
placing speakers near a corner, avoid locating them an equal distance
from the two adjacent srfaces.
When used in a home theater the front left and right speakers should
be separated from each other a distance of 0.8 to 1.2 times the seating
distance (assuming they are on the same plane as the center speaker).
For example, if the seating position is 10 feet from the viewing screen
and/or center speaker then ideally the distance between the left and
right speakers should be somewhere between 8 and 12 feet, (10 x 1.2ft
= 12ft). MTM style speakers are best installed in portrait orientation.
However, landscape is often used for the center speaker for aesthetic
or clearance purposes. If the speakers are located behind an
acoustically transparent screen then all the speakers should be
oriented portrait style. Tweeters may be aimed toward the listening
area by pressing the lens area along side the tweeter dome.
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 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 ensuring 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 sound quality will be impaired.
INSTALLATION
If the drywall has not yet been installed a Rough-in-Bracket (RIB-LCR)
may be used to reserve the speaker location on the wall. The RIB-
LCR brackets are available from the distributor or dealer where the
speakers were purchased. When these brackets are used the holes
are cut when the drywall is installed. The cable can be tied off on the
bracket after securing the cable to a nearby joist.
If the drywall is installed and the speaker locations have not yet been
established, then do so now. Assess the wall for possible concealed
