Figure 87. Individual Filters
From left to right the filters that are shown in Figure 87 are:
Variable Q high-pass filter with a Q = 1.3 to emphasize the bass and prevent distortion by cutting of
frequencies below the cabinet resonance
Equalization filters of various amplitudes, center frequencies, and bandwidths
A treble shelf
A Chebychev low-pass filter with a ripple of 1 dB to attenuate high frequencies
The combined response of these filters is shown in Figure 88.
