Sometimes the best summing comes from an asymmetrical crossover having different slopes and crossover points. This is often the case when the drivers themselves have very different positions and characteristics, as most are. In the passive π crossover circuit, slopes are asymmetrical and tweeter response is shifted by the inclusion of components R1 and R2, moving its crossover point and overall response. But frequency and slope are fixed by the components chosen. With an active crossover, it is nice to have some flexibility.
