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.
