AB  - A parametric loudspeaker utilizes nonlinearity of a medium and is known as a super-directivity loudspeaker. So far, the applications have been limited monaural reproduction sound system. We had discussed characteristics of stereo reproduction with two parametric loudspeakers. In this paper the sound localization in the vertical direction using the upper and lower parametric loudspeakers was confirmed by listening tests. The level difference between the upper and lower parametric loudspeakers were varied as a parameter. The direction of sound localization in the vertical plane was able to be controlled. We obtained interesting characteristics of the left-right sound localization in the horizontal plane. The simple geometrical acoustic model was introduced and analyzed. The analysis led to explain the measured characteristics.
