If the crossover frequency is set too low, the subwoofer will try to reproduce frequencies that it cannot accurately reproduce. This can cause the subwoofer to distort the sound or even damage the speaker. To avoid this, you should always make sure that the crossover frequency is set at least 10 Hz higher than the lowest frequency that the subwoofer can reproduce.
