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: www.preference-audio.com.
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.
