“12dB” (Low-Pass): Configures the filter
to attenuate frequencies above the indicated
filter frequency, at a rate of 12dB per octave.
This is useful for connection of subwoofers in a
bi-amplified system. This shallower slope gently
attenuates high-frequencies from your subwoofer
signal and is often well-suited for sedans and
coupes with trunks.
“24dB” (Low-Pass): Configures the filter
to attenuate frequencies above the indicated
filter frequency, at a rate of 24dB per octave.
This is useful for connection of subwoofers in
a bi-amplified system. This sharper slope more
aggressively removes high-frequencies from your
subwoofer signal and is often well-suited for
SUV’s, wagons and hatchbacks.

FILTER CONTROLS
Most speakers are not designed to reproduce
the full range of frequencies audible by the human
ear. For this reason, most speaker systems are
comprised of multiple speakers, each dedicated
to reproducing a specific frequency range. Filters
are used to select which frequency range is sent to
each section of a speaker system. The division of
frequency ranges to different speakers can be done
with passive filters (coils and/or capacitors between
the amplifier outputs and the speakers), which
are acceptable and commonly used for filtering
between mid-range speakers and tweeters. Filtering
between subwoofer systems and satellite speaker
systems is best done with active filters, which cut
off frequency content at the input to the amplifier.
Active filters are more stable than passive filters
and do not introduce extraneous resistance, which
can degrade subwoofer performance.
