The Crossover
This unique Low Impedance
Compensated Crossover (LICC) design
places inductors in series with the
woofer whose values are markedly
lower than conventional designs. This
reduces the amount of energy that is
typically wasted as heat and increases
the amount of energy that is
transformed into real acoustic power. It
also incorporates dynamic protection
for the compression driver from non-
linear signals.
