1. A method of creating a digital signal processing (DSP) filter to improve the transient response of a loudspeaker, wherein the loudspeaker is formed of multiple components, the method comprising:

  • identifying a substantially linear, time-invariant, and spatially-consistent loudspeaker mechanism causing transient response distortion;

    characterizing the identified mechanism;

    determining the characterized mechanism'"'"'s two-port response;

    establishing a target response for the characterized mechanism;

    calculating an ideal filter to achieve the target response; and

    designing a cost-reduced filter based on the ideal filter to thereby form a loudspeaker mechanism algorithm (LMA) filter.
