Sound design in cars, especially sound control, such as echo cancellation, noise control, sound zones require highly linear and in most cases time invariant behavior of the audio playback system. The weakest part in such a complex system is the electro-acoustic transducer (loudspeaker). Low efficiency, changing material properties, nonlinear distortion generation and limited output are common challenges for traditional transducers. Using a new active control technology those problems can be considerably reduced. In this paper the consequences of those improvements for audio design in cars are elaborated
