Loudspeaker Distortion Reduction

Nonlinear distortion and frequency response aberrations are the major weaknesses of low-frequency loudspeaker systems. A multiple-loop feedback system is presented that deals effectively with both of these problems. The feedback system, utilizing current and velocity feedback, also decouples the system Q factor from enclosure and driver parameters. A theoretical analysis is presented which has been the basis for several successful system designs. Extensive data on several practical systems have been taken to show the usefulness of this approach. Data for two of these systems are given here.
