Understanding Advent Legacy x-over, I have questions...

Hello
I have been staring at a picture online of the original Legacy x-over.
It seems like someone said that both caps are in the tweeter circuit
making it a second order hi pass.
That is a 32uf and 6uf cap. I think I understand the use of the 6uf cap which is a "normal" hi pass cap, and the 1.3 ohm resistor for attenuation, what is the 32uf cap doing?
The first order low pass with the coil and 32uf cap only,I think.
I have built the "stacks" of caps to replace the original'lytics".
(2x12uf + 7.5uf + .88uf bypass woofer) (6.2uf+.47uf By pass tweeter)
ESR of .37 woof and .39 Tweet.
I am hoping things will clear up for me when I actually remove old x-overs.
Thanks for all of your thoughts....and help.
tweak I must!...
