Abstract
A signal processing method and Automotive Audio System 290 comprising a tripolar loudspeaker configuration housed in at least one automotive head-rest assembly 200 or 500, whose radiation pattern, in conjunction with inter-element delays and other design features, is such that that passengers are afforded temporal and amplitude cues for achieving the desired soundfield appropriate for a variety of audio program material. Optionally, some or all of the headrest assembly transducers are aligned and configured with a Floating Waveguide member 470.
