Car cockpit is a critical environment for music; sound reproduction is in fact quite conditioned by reflections, echoes, engine noise and loudspeakers' set up. An important technique to improve sound comfort is a spatial equalization where both magnitude and phase of signal are controlled. This technique is performed by a stereodipole system where two closely loudspeakers are setting in front of listener and digital processing is performed real-time by a DSP board. Cross-talk cancellation is achieved using FIR filters, whose coefficients are obtained by inversion of the measured cockpit impulse response. In this paper an experimental validation of a double stereodipole system, one for driver and other for passenger, is performed by subjective evaluations inside a commercial car. Analysis of results of these tests, points out how the stereodipole system turns out to be able to emphasize sensations such as localization of sound source and naturalness of sound reproduction.
