If I ratio the nominal impedances [ie, 8 to 16] and back substitute into your 1K6a012dB crossover circuit for a Four-Pi Pro, I get the following values:
Woofer: C4 = 5 uF L2 = 2.0 mH
Tweeter: C2 = 4 uF C3 = 11 uF L1 = 1.2 mH
Referrring to the thread below on 16-Ohm CD compensation circuits, we have:
C1 = 0.33 uF R1 = 50R R2 = 16R
Do these values work well, or have I missed something?

Use the values of C1, R1 and R2 with the stock (8Ω) crossover. The load on the crossover is formed by the driver and the components C1, R1 and R2, and this is a solution that works well with R1=50Ω, R2=16Ω and C1=33uF. Summing is good and the initial shelf is nice and flat with compensation coming in at the right frequency.
I'm afraid my question was poorly stated. What I'm really asking is for ALL of the Four-Pi crossover component values when both the 2226 and 2426 are 16-Ohm versions.

Oh, I see now, gotcha. The tweeter is the hard one though - the midwoofer is easy 'cause it just has one series coil. Double it, go with a 1.4mH coil L2.
