Help me reverse engineer and modify a crossover

This is a 3 way crossover:

The biggest issue is that the two smaller coils dont have a label so i dont know the value.
I have drawn the circuit here:

is there a software or webpage that can put this circuit in, and it will tell me the corresponding frequencies? i will have to put in guess values for L1 and L2. maybe L2=1.5mH and L1 = 0.8mH?

the midrange is a tang band titanium wide bander. right now the tweeter is crossed over very low. i estimate somewhere in low 2k based on listening. i want to push it way way higher so that i am mostly listening to the wide bander and the tweeter kicks in much much higher. i also need to bring the tweeter level down 3 to 5 db. i am assuming that will be done by increasing that resistor value from 3 ohm. i know what an L pad is, but in here i only see one resistor for thre entire network. i could add additional resistors if needed. I have those fancy dayton audio 20Watt 1% resistors in 10ohm, 5.6 ohm and 2.3 ohms.

For the woofer i need to figure out what is the cut off currently. i am planning to use the

Dayton Audio DS175-8 6-1/2" Designer Series Woofer Speaker​


the orignal woofer says on it: BC143G. i thought its some B&C. but i cant find anything about it.

lol i didnt know that. im gonna get on it right now. i have two multimeters. do i need to disconnect the component or can i measure while its connected to other components?

edit: my two multimeters dont have measurments for inductance. at least there is no label that indicates it. there is V , A , ohm and capacitance and diode

i got you and you are right. i just installed VituixCAD and i am putting this crossover in. i dont know why they used a wide bander here and then use it in such narrow band. according to vituix this driver is being cutoff barely above 2khz. seems like a weird choice to me. why not just use a mid bass driver instead of the full range driver. ? so weird. i bypassed the entire crossover and listened to the driver direrctly out of amplifier. it seems to me to be completely capable all the way to above 10khz.
 
ok from vituix i learned that if i change the 5.1 micro farad capacitor to 1, it will do what i want.
i will also change that 3ohm resistor to 5.6 ohms. But i think i will send this speaker to danny richie of gr research. if he accepts it that is.
