Default Biamp with high-mid pasive filter.

hi i am quite new to audio amplifiers. I have previously build some guitar pedals and guitar preamp/powers amp.
So now i want to build stereo bi-amp with passive high-mid filter(chip or solid state).
Some this like this.

But this schematic is quite unclear to me. Any help will be appreicated. Or can you suggest any similar circuits with pcb layout.
