The Audio Spotlight uses a beam of ultrasound as a "virtual acoustic source", enabling unprecedented control of sound distribution. The graph to the right shows the real sound field of the Audio Spotlight versus the theoretical maximum directivity of any loudspeaker, panel, dome, or "shower" of the same size. As shown by this comparison, no loudspeaker in the world can approach the level of control provided by Audio Spotlight technology. For more on the theory of this device, go to http://www.holosonics.com/tech_directivity.html or download Joe Pompei's PhD thesis from DSpace at MIT Joe Pompei's PhD Thesis
