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.
