Rocking modes are caused by small imbalances in the distribution of stiffness, mass, and force factor. A measurement technique to determine these root causes, using laser vibrometry, parameter identification, and root causes analysis has been presented in a previous paper. This paper focuses on the application of this technique to examine rocking modes in nonlinear domain. An incremental DC-offset is applied to the loudspeaker to examine changes of the root causes of the rocking throughout the working range of the loudspeaker.
