A simple loudspeaker array and associated crosstalk canceler for improved 3D audio
Jerald L. Bauck · Journal of the Audio Engineering Society · 2001
A new technique which enlarges the sweet spot of three-dimensional audio when using loudspeakers is described. The technique, a modified short-baseline array comprising horizontally distributed multiway driver configurations plus specially designed imaging filters, substantially enlarges the listening sweet spot without requiring the very large low-frequency signal excursions of prior methods. While the technique is particularly well suited to applications that use a television or video monitor, it also provides an alternative to the conventional stereophonic loudspeaker pair and the front loudspeakers in multichannel and home theater applications.
