FIELD: radio engineering. SUBSTANCE: electric signal arriving at loudspeaker input is converted into acoustic signal with loudspeaker being operated under debugging and working conditions. Under debugging conditions it is tested for limited number of distortions by converting audio signal distortions at loudspeaker output into electric signal and test results are recorded. Under working conditions loudspeaker is connected to computer holding pre-recorded test results; the latter are changed to opposing ones and added to arriving electric signal in this way converting them to correcting signal. Then correcting signal obtained depending on parameters of electric signal is passed to loudspeaker. EFFECT: improved audio characteristics of not only high-quality but also quantity produced loud speakers. 5 cl, 1 dwg
