The embodiments of the invention concern a method ( 400 ) and system ( 100 ) for modeling transducer non-linearities. The method can include converting ( 402 ) a transducer signal to a displacement signal that is proportional to a transducer cone displacement, and applying ( 404 ) a correction to the displacement signal. The transducer signal can be one of an input signal to the transducer ( 102 ) or an acoustic output signal of the transducer. The method can account for at least one mechanical transducer non-linearity which can be a cone excursion, a diaphragm stiffness, or a diaphragm displacement. The method can account for at least one acoustic transducer non-linearity which can account for an acoustic jetting out of a port. The system can further include a sensor coupled to said transducer for physically measuring a cone displacement.
