1. A sound signal processing device configured to supply an output sound signal to an amplification device configured to supply a first sound signal to a high-frequency speaker and a low-frequency speaker, the sound signal processing device comprising:
a high-pass filter configured to remove a low-frequency component from an input sound signal to generate a high-frequency sound signal;
an amplitude limitation circuit configured to limit an amplitude of the input sound signal at or below a reference value to generate a second sound signal, the reference value corresponding to a clipping voltage of the amplification device;
a low-pass filter configured to remove a high-frequency component from the second sound signal to generate a low-frequency sound signal; and
a synthesis circuit configured to synthesize the high-frequency sound signal and the low-frequency sound signal to generate the output sound signal.
