How many uF the cap for the tweeter to do the sum measurement?
can be enough 24uF because I have one on hand?
Build the XO filter as jReave suggested. Look at the post 221.
After you wire the passive parts to your tweeter, record the FR
so we see how it performs.
Merlin,
use whatever filter you want. A normal procedure would be to
start installing parts one by one. First a resistor, then a resistor
with a say 8,2 uF cap, then a shunt coil 0,22 mH or any part value
you wish or have at hand. Record every FR for each change. Mic
should not be moved.

XO filter in post 242 is unusual. I tend to use not to many parts.
What matters is how do all these parts work together and see
the difference with and without them. Try it.

The first two graphs are without filters, right ? Do the measuring
with bass filter only and post it. The same with tweeter and its filter.
Make a picture that shows both of the slopes intersecting without their
sum. Extend the window for the bass to show 200 Hz and up. For the
tweeter it is enough from 1 kHz.

I guess there must be an option in Holmimpulse so you can
include both of the measurements in the same display.
In the meantime, cut the RLC filter out of the circuit
and record it. I will take a look at the pictures later.

Yes, just cut one wire either on R or L or C. I just had a look
at the graphs and definitely this XO filter version is not high
quality solution. There is the 5 dB deep from 1k to 6 kHz.
