MOUNTING
The EXACT4.3X Passive Crossover can be mounted in virtually any location inside the
vehicle. Be sure not to mount the EXACT4.3X outside the vehicle, or in a location
THE
where it may be exposed to dirt or moisture (e.g., the engine compartment, inside a
EXACT4.3X
wheel housing, inside a door, at the bottom of a leaky trunk).

MIDRANGE
The provided crossover also allows for two positions of midrange level control. A

switch under the clear plastic crossover cover sets one of the two positions --

MIDRANGE PRESENCE -- ON/OFF. The ON position provides increased midrange, a
feature useful for adjusting midrange vocal presence. See Figure 7.
Tweeter Protection Activation
DYNAMIC
Under high power/high volume conditions, the dynamic tweeter level control (DTLC)
TWEETER
circuit may activate. The purpose of DTLC is to prevent failure of the tweeter by
LEVEL
reducing its output when necessary. Upon activation of the DTLC circuit, there will be
CONTROL
an audible decrease in high frequency output as well as a visual indication from the
DTLC light bulb (see Figure 7). The circuit is self-resetting -- if the DTLC activates, turn
the volume down and normal operation will resume momentarily.
Tweeter Attenuation
The EXACT4.3 system has been designed to provide optimum sound in a variety of
installation locations. The provided crossover allows for three positions of tweeter level
control: HIGH, MED and LOW. The LOW position is useful for using the EXACT4.3 in
rear-fill applications. A switch under the clear plastic crossover cover sets one of the
three positions. See Figure 7.
