The invention relates to a sound box control technique, in particular to a speaker system regulation method. The method comprises a speaker system model establishing step and a virtual input process parameter correcting step, wherein a speaker system model comprises a plurality of sound box models. Each sound box model is corresponding to a hypostatic active sound box and includes a virtual input process parameter and a virtual output process parameter, the virtual input process parameter includes one or more virtual DSP (digital signal processor) data, each DSP data includes multilayers of DSP parameters in the same type. Thus, no matter how many layers of DSP parameters each hypostatic DSP of the hypostatic sound box includes, the technique can realize multilayer adjustability of the input process parameter in the system layer so as to simplify the operations of debugging and correcting of the speaker system, improve the debugging efficiency, and guarantee the debugging effect of the system.
