BUILT-IN TWEETER
PROTECTION CIRCUITRY:
The XR Crossover networks are equipped with
an advanced electronic tweeter protection circuit
designed to minimize the possibility of tweeter
failure. This electronic device monitors current going
to the tweeter and will disconnect the tweeter from
the signal when it senses overload. Should this occur
while listening to the audio system, simply reduce the
volume for a few seconds and the protection circuit
will reset itself automatically.
ADJUSTABLE TWEETER LEVEL:
Your XR Crossover networks provide five levels
of tweeter adjustability designed to compensate for
different mounting locations, vehicle interiors and
personal taste. These levels are selectable via a set
of pins located under the clear cover of each
crossover case. We recommend that you begin
listening at the “REF” (Reference) position. If the
sound seems too bright or aggressive, experiment
with alternate tweeter level settings by moving the
jumper connectors. It is safe to switch jumpers
while
the
system is
playing.
ADJUSTABLE MIDRANGE PRESENCE:
Your XR networks also provide a unique
midrange presence control, located under the clear
cover.The midrange presence is selectable via a set
of pins and allows for three settings:“High-Mid”,
“Normal” and “Low-Mid”.The settings affect the
overall amplitude of the upper midrange response
of the XR component woofer. We recommend that
you begin your listening with the “Normal” setting
and adjust up or down as needed to compensate
for mounting location or personal taste.
SPEAKER PLACEMENT
CONSIDERATIONS:
A component system gives you the ability to place
the woofer and tweeter separately in your vehicle
interior.This can be good or bad, depending on how
it’s done. As a general rule, the tweeters should be
placed relatively close to the woofers for best tonal
balance and most coherent imaging (the closer, the
better). Any separation greater than 8 inches (20
cm) is likely to result in degraded sound quality.
Avoid placing tweeters where they will be blocked
by objects in the interior of the car (including seated
occupants). When selecting a mounting location, look
at both sides of the car to make sure that this
location is clear on both sides.You can always
experiment with tweeter placement before
committing to a final mounting location. Simply
connect the rest of the system and allow plenty of
wire length for the tweeters. Using velcro or similar
material, attach the tweeters in different locations
until you find the one where they perform best.
Woofers will usually be placed into factory
speaker locations. If you have some woofer
mounting flexibility, keep the following in mind:
Lower mounting locations, such as the lower front
corner of a door or a kick-panel provide the
greatest path length distances for the sound emitted
by the woofer. For this reason, they are generally
more desirable than higher mounting locations.
