SETUP

Highpass Filter

Highpass filters attenuate low-frequency signals at 24dB per octave. The curves in the graph above indicate the frequency response of each crossover point. From left to right, the curves represent crossover points from 30 to 120Hz. This graph does not include the THX 80Hz crossover point, which attenuates low-frequency signals at 12dB per octave.
