The QSE-216 2-Way crossover network included in your Q speaker set
is equipped with individually selected sound frequency components, gold
connection terminals and gold terminal jumpers, together with reinforced
conductor tracks with 140 copper plating. In addition, it uses our new
Balanced Temperature Technology which, in combination with the cast
aluminium baseplate, means that the temperature variations between
the different components therefore work at the same, exactly pre-defined
temperature.
Your QSE crossover nectwork is also equipped with a special tweeter
protection, which prevents damage to the tweeter voice coil. The various
different connections and setting variants offer all the conditions required
for the optimal adjustment of the speakers to the vehicle acoustics and to
your individual listening preferences.

The crossover is necessary for the
proper operation of the component
speaker system. Make sure the wires
are securely attached and that there
are no stray strands of wire contacting
other terminals. Mount the crossover
to a secure surface that is free of
interference from window mechanisms
and excessive moisture.

Leaving the jumper connected between tweeter negative and A provides
a boost in the upper midrange, between 3kHz and 8kHz. The Negative
tweeter wire needs to be connected on the jumper.
