1. A method for spatially enhanced sound reproduction in which audio speakers are located substantially at two locations whereas the sound experienced by a listener is perceived to emanate over a wide field and not from discrete locations, said method comprising the steps of:

  • radiating first sound waves having a sum component and a difference component so that said first sound waves are emanated from a generally vertical axis at a left-hand location;

    radiating left difference sound waves so that said left difference sound waves are emanated from a generally horizontal axis at said left-hand location to acoustically combine with said first sound waves emanated from said vertical axis;

    radiating second sound waves having a sum component and a difference component so that said second sound waves are emanated from a generally vertical axis at a right-hand location;

    radiating right difference sound waves so that said right difference sound waves are emanated from a generally horizontal axis at said right-hand location to acoustically combine with said second sound waves emanated from said vertical axis.
