Also helpful is bass equalization and subsonic filtering. When cascading active filters
with the existing passive filters within the speaker system, be sure to allow for ade-
quate frequency overlap. For instance, if the passive crossover is set at 500 Hz, select
a low pass corner frequency of 600 Hz and a high pass corner frequency of 450 Hz to
prevent a suck out in the response at 500 Hz. The controlled distribution of power af-
forded by the active crossover results in less amplifier strain (better clarity), greater
dynamics, and lower intermodulation distortion. However, a basic understanding of
crossover slopes and crossover frequencies within your loudspeaker will be needed to
implement the active crossover successfully.
