The "Safe Operating Area" (SOA) for a loudspeaker is based on its electro-mechanical-thermal model. Depending on a speaker's inefficiency, some of the power is dissipated as heat rather than mechanical/acoustic energy. By understanding the characteristics of the speaker, Smart Amp is able to drive the speaker harder, without causing the speaker to thermally overload; or, suffer voice coil over-exclusion and fail. SMART SOA are parameters that are differentiated by a PPC GUI into coefficients that the algorithm uses.
