Fine Tuning Your dX Component System
Now it’s time to fine tune your dX component system to get best sound quality possible. The
dX systems are designed to allow you to adjust the sound to best suit your car’s acoustics
and your personal taste.
Each of the adjustments described below makes a subtle but audible change. There are 12
possible combinations of settings in the crossover alone to aid you in getting the perfect
sound for your ears in your car. A table showing all the possible combinations appears
below. Take your time, try all the options. Your patience will be rewarded.
4. Insert front half of flush cup into the hole and
manually push clamp ring (Figure 3) on until cup
is tight on front surface.
5. Put tweeter in bottom half of flush cup and twist
lock to front half of assembly created in step 4.
6. Cut the supplied tweeter wire in half.
7. Connect wires from the tweeter terminals of the
crossover to the tweeter wires. Be sure that connector
ends are the same as those on the tweeter. Connect
the white striped wire strand to the (+) terminal
of the crossover tweeter output and to the red wire
on tweeters (Figure 2).
8. The tweeter can now be pivoted to the desired
angle by applying firm pressure to the edge of
the tweeter module.
dX3000 Component Tweeter Hook-up
When purchased as a separate unit, the dX3000 tweeter includes a crossover network
integrated into the hook-up wires. This high pass filter allows the dX3000 to be used
with other components. It is important to maintain correct polarity. The red wire connects
to the positive (+) amplifier terminal and the black to the negative (-) amplifier terminal.
If your system contains an active crossover, you may bypass the in-line crossover and wire
the tweeter directly to the output terminals of an amplifier which has a high pass filter
(crossover) on its input. The minimum crossover point should be 2 kHz at 12dB per octave.
DO NOT USE THE TWEETER WITHOUT A CROSSOVER NETWORK.
Damage to the tweeter from thermal overload will result without the protection provided
by a crossover and will void your warranty.
