A dynamic bass equalization circuit has an amplitude dependent gain that is dependent upon the audio electrical signal amplitude and a dynamically adjusted frequency response that varies with the amplitude dependent gain. In one implementation, the dynamic bass equalization circuit includes a Sallen-Key high pass filter that includes an amplifier with a negative feedback path. The dynamically adjusted frequency response is provided by a parallel pair of reversed diodes connected in the negative feedback path.
