Horn loudspeakers suffer from production of high acoustic distortions. Based on an ideal physical model, an equivalent lumped parameter circuit is determined for a horn-loaded compression driver. From the nonlinear differential equation of this circuit, a compensation algorithm is implemented on a DSP for reducing nonlinear distortion caused by the adiabatic behavior of air. Test results are given.
