Crossover filter design

Hey friends!

So in a Multiband Compressor context, I’m in need of crossover filters. Since I’m all self taught, I’m kinda stuck here:

The commonly used Linkwitz filter will add a 360* rotation to my audio as far as I understand. But what exactly would that mean for let’s say my low end? How could I best go about designing a filter that won’t change up my transient material, be flat in freq response and is coherent after the actual dsp?

If anyone can help me out that’d be much appreciated.

Best,
Raphael
