The technology described in this document can be embodied in an acoustic enclosure for a speaker system disposed in a portion of a vehicle seat. The acoustic enclosure includes a rigid plate configured to be attached to a frame, a first section, and a second section. The rigid plate configured to support a speaker disposed in part within the acoustic enclosure. The first section is constructed from expanded resin, and disposed in contact with the rigid plate. The second section is disposed in contact with the first section, between the second section and the rigid plate. The first and second section together define a housing of the acoustic enclosure that includes at least one cavity configured to accommodate a portion of the speaker.
