A loudspeaker assembly is disclosed that includes a headrest having a front face and a rear face; a bass dipole loudspeaker mounted to the headrest, wherein the loudspeaker includes a diaphragm having first and second radiating surfaces, wherein the radiating surfaces are located on opposite faces of the diaphragm, wherein the diaphragm moves at bass frequencies such that the radiating surfaces produce sound; a bass waveguide to guide bass produced by the first radiating surface via a forward-facing opening provided by the waveguide, wherein the loudspeaker is mounted such that bass produced by the second radiating surface propagates out from the rear face and such that the first radiating surface is closer to the rear face than to the front face. The forward-facing opening is larger than the first radiating surface as projected onto a plane perpendicular to a movement axis of the loudspeaker.
