The summed response of filters at the crossover frequency is determined by the filter Q, not the filter slope. There can be a major dip at the crossover frequency with 2nd order/2nd order passives, as the total phase shift at the crossover frequency is 180 degrees. That's usually addressed by reversing polarity on the high frequency element, but a better option is to use a 3rd order high pass, which eliminates the 180 degree phase shift, while giving better driver protection and lower THD. Actives tend to not have phase summation issues.
