We have a lot of options nowadays on how electronics are designed. Many if not most decisions revolve around cost. Bi-amping is a good and well-known solution to the sound pressure issue. There are other solutions that will work but cost more to design and implement.

The idea is to get the correct frequencies directed to the correct speaker and to drive those speakers hard enough to produce the sound pressure level desired.

The electronic components for passive crossover are pretty simple, being capacitors, inductors, and resistors. There are both component and design issues that define how well any of this works. More complex better designs cost more money to produce.

All very cool stuff if you have an interest in electronics.
