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 three
levels of tweeter adjustability designed to
compensate for different mounting locations,vehicle
interiors and personal taste (see Diagram B).
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 crossover networks also provide a
unique midrange presence control, located under
the clear cover (see Diagram C). 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 woofer
element.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:
In most cases,your speakers will be placed into
factory speaker locations. If you have some speaker
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 speakers. For this reason, they are generally
more desirable than higher mounting locations.
Higher mounting locations will usually result in
extreme near-side soundstage bias which
compromises the stereo listening experience.
