hi,
I have pretty much zero knowledge in how to build a crossover, i've been watching some videos and messing about with xsim with a few speakers online just to test the waters.
Just want to know if this looks right and if i'm heading down the right path?
Many Thanks

With 100 ohm resistor infront of woofer you will hear no bass, or little. Remove it. Woofers typically do not need attenuation, since mids and tweeters are more efficient.
What is the point of attenuating signal into each branch?

One more thing...good luck finding 240mH inductor. Even 36mH is a lot. You will have to spend more money on inductors than speakers.
What drivers are using please, and are you using measurements or makers' data?
I wouldn't put a resistor in series with any woofer, it may overheat and give you an unexpected barbeque.

22 mH in the tweeter circuit seems like a red flag also.
Starting off with some textbook crossover component values is helpful. You can use an online calculator for higher order crossovers, or use XSim's built-in circuit blocks for 6 and 12 dB/octave crossovers. These values are typically adjusted once real-world impedances and frequency responses are involved, but they give you a general idea about the typical values to expect for a given impedance and cross point.

Similar discusion, it will give you idea -> https://www.diyaudio.com/community/threads/3-way-my-version.419693/
From looking at the fr response you provided, you selected 70Hz and 2kHz crossover points. Why?
First, 70Hz seems rather low. Its a subwoofer territory. You select such a low crossover point, if you are planing to place subwoofer in separate box further from mid and tweeter. Otherwise such low crossover point makes no sense.
Typically starting point is 300Hz and 3kHz, but this should be selected based on actual drivers, where they are starting to beam. That is on axis and of axis behaviour.
I assume you have not selected the drivers yet.
This page can help you to understand a bit about crossover design.
