AB  - The previously presented theory of interface intermodulation distortion (IIM) is extended to cover the analysis of the influence of certain power amplifier design parameters on this effect. It is shown that the amplifier distortion spectral density is altered by the loudspeaker, and that the most important single parameter increasing this effect is a high open-loop output impedance. The usual specification of the closed-loop output impedance of the amplifier has, in this respect, little relevance.
