Various implementations include seats and related loudspeakers. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly. The loudspeaker assembly includes at least one driver for generating an acoustic output; and an acoustic exit fixed in the seat backrest portion and angled to provide the acoustic output to a location below a nominal ear position of an occupant of the seat, wherein a firing angle of the at least one driver provides the acoustic output to achieve a consistent frequency response across a range of positions deviating from the nominal ear position.

A vehicle includes a cabin interior, a floor, and a tailgate at the rear end of the cabin interior, wherein at least a portion of the tailgate pivots between a vertical closed position and a horizontal open position. The vehicle has a first seat track assembly is supported on the floor in the cabin interior, a second seat track assembly supported on the tailgate, and a seat assembly. The seat assembly including a first seat panel, a second seat panel, a bracket that allows the first seat panel and the second seat panel to pivot between a forward facing position and a rearward facing position, and a guide supporting the bracket on one of the first and second seat track assemblies, wherein the seat assembly may slide rearward along the first seat track assembly onto the second seat track assembly when the tailgate is in the open position.
