Basically, to get Lp, filters from 12dB/Oct, up to 48dB/Oct, need you to set as follow the Q, given the
same cutting freq. to all of them:
Butterworth
12dB/Oct -----> One Cell / Q1=0.70
24dB/Oct -----> Two Cells / Q1=0.55, Q2=1.30
36dB/Oct -----> Three Cells / Q1=1.95, Q2=0,70, Q3=0.50
48dB/Oct -----> Four Cells / Q1=2.55, Q2=0.90, Q3=0.60,Q4=0.50
Linkwitz-Riley
12dB/Oct -----> One Cell / Q1=0.70
24dB/Oct -----> Two Cells / Q1=0.70, Q2=0.70
36dB/Oct -----> Three Cells / Q1=0.55, Q2=1,30, Q3=0.70
48dB/Oct -----> Four Cells / Q1=0.55, Q2=1.30, Q3=0.55, Q4=1.30
Bessel
12dB/Oct -----> One Cell / Q1=0.50
24dB/Oct -----> Two Cells / Q1=0.55, Q2=0.80
