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