The one-cycle time offset between the high-pass and low-pass sections typical to symmetrical constant-amplitude crossover networks implies that the polar pattern is controlled by a single driver (or driver group) during the onset and end of a sharp transient. This implies that the ratio of overall radiated energy to the input energy near the crossover frequency depends on the duration of the transient, which again affects the sound pressure in a reverberant field.
