Highpass Filter
Highpass 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 30 to 120Hz. The graph above does not
show the THX 80Hz crossover point, which is 12dB per octave.

Lowpass Filter
Lowpass filters attenuate high 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 30 to 120Hz.
In general, low frequencies will be redirected from speakers with the highest crossover points to speakers 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.
