Seamless Transition Between Subwoofer and Speakers
The fine tuning process includes
creating a smooth transition of music
between the SuperNova MKV and the
next speaker in line : usually a woofer or
a large midrange. As shown in the
graph across, a smooth transition
between lower and upper bass is
directly relative to the crossover setting
and the capability of the next speaker in
line to reproduce low frequencies.
