Preliminary psychoacoustic tests results of a simple method to minimize the effects of interaural crosstalk in a nearfield stereo/binaural loudspeaker monitoring setup are described. The results show accurate horizontal imaging and localization over a 120-degree frontal angle for both intensity-difference and delay-difference stereo program material. The method depends on the use of a flat vertical boundary erected between two front-positioned side-by-side nearfield monitor loudspeakers. The listener is situated facing the monitors with his ears on opposite sides of the boundary. Advantages include: independent control of amplitude, phase, and delay at each ear; solid frontal out-of-head imaging for side-to-side head shifts and head rotations; extremely good center image; creation of realistic lateral beyond-the-loudspeaker acoustic images; minimization of crosstalk comb-filtering effects on the frequency response; and good results with both stereo and binaural program material.
