Audio Spotlighting was invented by Dr. F.
Joseph Pompei.
Production of focused beams of sound.
Uses ultrasonic wave as carrier signal
Non-linearity of the air aid the device for its
working.

ADVANTAGES1.Can focus sound only at the place you want.
2.Ultrasonic emitter devices are thin and flat and do not require a mounting cabinet.
3.Focused sound travels much faster in a straight line than conventional loudspeakers.
4.Dispersion can be controlled - very narrow or wider to cover more listening area.
