8. A method for providing augmented spatialized audio in a vehicle cabin, comprising the steps of:
outputting to a first binaural device, according to a first position signal indicative of the position of a first user's head in the vehicle cabin, a first spatial audio signal such that the first binaural device produces a first spatial acoustic signal perceived by the first user as originating from a first virtual source location within the vehicle cabin, wherein the first spatial audio signal comprises at least an upper range of a first content signal, wherein the first binaural device is an open-ear wearable, wherein the first position signal is based on a headtracking signal, the headtracking signal being output from a headtracking device including an inertial measurement unit;
outputting to a second binaural device, according to a second position signal indicative of the position of a second user's head in the vehicle, a second spatial audio signal such that the second binaural device produces a second spatial acoustic signal perceived by the second user as originating from either the first virtual source location or a second virtual source location within the vehicle cabin, wherein the second spatial audio signal comprises at least an upper range of a second content signal, wherein the second binaural device is an open-ear wearable; and
driving a plurality of speakers with a driving signal such that a first bass content of the first content signal and a second bass content of the second content signal is produced in the vehicle cabin, wherein the plurality of speakers are driven in accordance with a first array configuration such that the first bass content is produced in a first listening zone within the vehicle cabin and in accordance with a second array configuration such that the second bass content is produced in a second listening zone within the vehicle cabin, wherein in the first listening zone a magnitude of the first bass content is greater than a magnitude of the second bass content and in the second listening zone the magnitude of the second bass content is greater than the magnitude of the first bass content.
