The calculated values

Cross-over frequency 1000 Hz

C1 = 9.89 uF

C2 = 49.41 uF

C3 = 23.71 uF

L1 = 1.05 mH

L2 = 2.64 mH

L3 = 0.53 mH

the calculated values are rounded to 2 decimals

Recommended values for capacitors

C1 = 9.1 uF + 0.68 uF + 0.1 uF  parallel

C2 = 47 uF + 2.2 uF + 0.2 uF  parallel

C3 = 22 uF + 1.7 uF  parallel
