Crosstalk cancellation expands stereo images from ±30° to as wide as ±90°

Evidence

Although intended for the reproduction of binaural, head-related recordings, listening to conventional stereo recordings is possible, in which case, what does one hear? It depends on how successful the crosstalk cancellation is, because what is happening is that hard-panned L and R images are delivered to the respective ears as isolated signals. The perception can be of images to the sides of the listener. In the extreme, the normal ±30° stereo soundstage expands up to ±90°, which is not subtle. For large classical works it might be considered exaggerated. Popular music can sometimes generate isolated 79. musicians well away from where one normally expects the band to be. It is a sound effect, and personal taste prevails. — Toole, Floyd E, Sound reproduction- the acoustics and…, 306
