The slope is to match the roll-off of your speakers. Ported and passive radiator speakers roll-off at 24dB/oct, sealed speakers at 12dB/oct.
After finding what frequency you want to cross over at (80Hz for instance), next you find the phase; play a sine wave at the frequency you cross over at, you can find clips on YouTube or on websites (like this one), and adjust your phase/polarity until it registers the loudest in the seating area (so it requires two people or leaving a SPL meter in your seating area), you want the loudest as that’s when the phase is alligned, any misallignment causes a reduction in output, and fully opposite in phase completely negates the sound.
