Performance Criteria for Speakers in Digital Car Audio Systems

In an automotive sound system, the environment plays a major role in the total acoustical performance. Most of the design goals are the same as in home entertainment systems. However, the presence of road noise and restricted space availability for the speaker location must be considered as design criteria. High excursion requirement to overcome the masking effects introduces several nonlinearities. Since cars behave differently under dynamic conditions, speakers must be designed selectively for high performance.
