What are some good sources online to learn about passive crossover design? Right when I think I'm beginning to figure it all out, I learn something new (Baffle step diffraction, driver impedance matching). I'm just beginning to understand the purpose of L-Pads and Zobels but have no idea how to calculate such elements in a crossover. Is there a complete and comprehensive guide to crossover design? I really want to understand all of the intricacies that going into making a crossover, but find it hard to find a singular source that sort of lays out the basics lays down the very basic concepts and calculations.
My current project is a Modula MT (Jon Marsh) with the major difference being that I'm sealing the enclosure.

Also this is sort of a side question... but could someone explain how it's possible to design a speaker that accepts both non-bi-amping and bi-amping? When bi-amped (Assuming that the speaker you're driving is two-way, TM) would the tweeter continue to receive a signal affected by the original passive crossover while the woofer would be driven directly by the secondary amp? Or is it the opposite? Or something completely different? It's to my understanding that the benefit of bi-amping is that you can drive the tweeter and woofer independently (Basically shift the crossover outside of the speaker cabinet), so what happens to the original crossover when you do this?
