AB  - The nonlinear stiffness K(x) and the reciprocal compliance C(x) of suspension parts (spider, surrounds, cones) and passive radiators (drones) are measured versus displacement x over their full range of operation. A dynamic nondestructive technique is developed, which excites the suspension parts pneumatically under similar conditions as occur in a loudspeaker. The nonlinear parameters are estimated from the measured displacement and sound pressure signal. This guarantee results with highest precision as well as simple handling and short measurement times. The theoretical basis for this new technique is developed, and the practical handling, the interpretation of the results, and their reproducibility are discussed.
