2. Making something look similar is one thing but this device is an actually working sound manipulator and the measurements are super critical.
I think the fringes of frequency response must be built in. For example, my 811 horns are rated to 800Hz, yet they're utilized in sytems with 800Hz / 6dB passive crossovers like my Heathkits. There must be a fudge factor there.

FWIW, I have a Behringer 2496 active XO and will eventually be bi-amping my system. I can adjust slopes to 24dB and tune the final XO point anywhere I need it to be.
