These are Butterworth filters. I will give the component values and a picture of the high pass - low pass circuit used in the 150 to 1000 hz bandpass.
150 Hz lowpass: R = 1 meg, C1 = 1.48nF, C2 = 3.76nF, C3 = 215pF
150 Hz highpass: C = 1nF, R1 = 762K, R2 = 299K, R3 = 5.24MEG
1000 Hz lowpass: R = 100K, C1 = 2.2nF, C2 = 5.6nF, C3 = 322pF
1000 Hz highpass: C = 1nF, R1 = 114K, R2 = 44.9K, R3 = 786K
20kHz lowpass: R = 10K, C1 = 1.1nF, C2 = 2.8nF, C3 = 161pF
Use the closest standard value to those listed.
