1. A vehicle headrest comprising:
a main body having a front surface arranged to support a back of a head of a user and a pair of acoustic channels each formed in part by a side wall having a front edge that is offset from the front surface, the main body comprising a portion configured to receive first and second transducers having a center-to-center spacing (Dimension A) of approximately 130 millimeters (mm) to approximately 240 mm; and
a transducer mount in each of the pair of acoustic channels for mounting respective ones of the first and second transducers, wherein a dimension (Dimension C) is defined by a rotation angle of the transducer mount relative to a centerline of the vehicle headrest, wherein Dimension C is approximately −20 degrees to approximately zero degrees, such that when mounted to the respective transducer mounts, the first and second transducers are oriented at a forward firing angle or an inward firing angle relative to the centerline of the vehicle headrest,
wherein a dimension (Dimension F) is defined by an amount that the front edge of each side wall is recessed from the front surface and is equal to or less than approximately 35 mm.
