Abstract
A method for dynamic equalization is performed at a system. The system receives an electronic audio signal. The system monitors available headroom based on two or more of: an amplifier of the system, a change in volume of the system, characteristics of a transducer of a loudspeaker associated with the system, and the audio signal. Responsive to a change in the available headroom, the system modifies one or more parameters of an equalizer to at least a portion of the signal in order to extend a physical low-frequency response of the loudspeaker, the one or more parameters comprising a gain for the and a frequency.
