Crossover design, Xsim questions

[andriux3000]

Hello,

I am designing my first set of speakers and I have questions about crossover.
I have designed this theoretical crossover with Xsim, difference between the loudest and the most quiet points in this graph is around 5db but that is mostly due to speaker curves as I understand.

1. I don't have access to driver measurement equipment and will use DSP EQ tuned by ear so is it really necessary to try to find a friend that has a studio and pro mic or this would do?
2. Is there a difference if I should solder L-pad before or after the highpass?
3. By manufacturer's datasheets my woofer would play up to 1,5 kHz and tweeter from 1,4 kHz up. Is 100 Hz enough to crossover in practice?
4. Can I trust FRD and ZMA graphs found online?

Drivers I have chosen so far:
Woofer: Tang Band W5-1138SMF
Tweeter: Dayton Audio Reference RST28F

I believe you want it after the high pass just so the resistors only see the HF energy and don't have to dissipate energy from all freqs.
