First order, ~.12mH coil in parallel with tweeter for 11k ish, 22 ohm resistor pad also in parallel.

Woofer currently has 15ohms-10uF in parallel with it.

Both these values to be trimmed.

What does the R in the woofer circuit do?

I am considering something quite similar for 207 + FT17 -- i was thinking of an extra series cap on the tweeter.

Its a shot at baffle step compensation, the woofer is being run pretty much full range. A straight cap in parallel gives the normal 6dB/oct roll off. All this assumes current source amplifier. Normally tweeters are crossed to with cap, doesnt work out same here. All XO components go in parallel with current source amp.
