The stereo speaker system is mountable at the back of a seat and includes two speaker assembly enclosures mounted on a spacer bar on a stand or captured between the seat back and a room wall to maintain the two speakers at a desired separation and orientation behind the head of the seat occupant. Each enclosure includes a chamber substantially occupied by a speaker assembly and a duct portion for directing the sound toward the ears of the listener who is occupying the seat.
