Crossover board Accuphase F-20

Hi, I have a Electronic Frequenzy Divider from Accuphase ( F-20 ).

Who comes with different crossover cards, 70-12000Hz.

I have 100Hz, but with old filter I crossed at 200Hz.

So I can by the 180Hz or 250Hz card, think the 290Hz is to high.

The crossover is between Seas Excel W26 (10inch) and Seas Excel W18EX (6.5inch).

OR!! is it just to swap the resistors/caps in the 100Hz card to get even 200Hz?

And using only the 24db alternative only few comonents has to change.

Enyone have a ide how to find the value of the components for 180/200 or 250Hz?
