3-25
In general, low frequencies will be redirected from loudspeakers with the highest crossover points to loudspeakers with the lowest crossover
points. Low-frequency signals lower than the lowest crossover point will be redirected to the subwoofer. If the lowest crossover point is
FULL, low-frequency signals, excluding LFE information, will not be redirected to the subwoofer.
High-Pass Filter
High-pass filters attenuate low frequencies at 24dB per octave. The curves in the
graph above indicate the frequency response of each crossover setting. From left to
right, the curves represent crossover settings from 30Hz–120Hz. The graph above
does not show the THX 80Hz crossover point, which is 12dB per octave.
