Why and How to Test Voice Coil Position in Production Line

"The large signal behavior of electrodynamic loudspeaker transducers at medium to high excursions is characterized by various nonlinear mechanisms, mainly related to the suspension and the motor. They define the sound quality, stability and peak performance of the final audio system. The nonlinear characteristics of a transducer are already set during the design phase — restrictions are related to price, size, weight, and the target market. The employed materials and geometry of motor and suspension mainly define the overall large signal performance."
