My question is in regard to the third order Butterworth topology.

Specifically the order of the Caps in serial.

The original design specifies as follows:

C1 = 33uF

L2 = .33mH

C3 = 20uF

The only hesitation I have with this design is that every manual formula and every computer modeling program for Crossover design, always show the Smaller Capacitor first in series with the Larger Capacitor.

So I am curious why the original mfg has this reversed.

Since Capacitors in series always Sum the same regardless of size/order...

???

**Does it matter the order in which the two caps are placed in series on the board**???
