A previous paper by some of the authors investigated a solution to minimize the loudspeaker inductance based on an additional fixed coil positioned in the gap with 2 additional terminals. This device is referred as A.I.C. (Active Impedance Control). In this paper a suitable electrical circuit model for such loudspeaker with 4 terminals and 2 coils is proposed.
