Secret Sound is a museum quality parabolic speaker which projects a focused beam of sound onto any exhibit without distracting audio spillover. It was designed by museum professionals to be easily installed, ceiling mounted at any height and maintenance free. Secret Sound has been in use by major institutions around the world since 1986. The speaker housing combines reduced size and elegant design with high-tech materials and performance. Only slightly larger than a baseball, the molded-composite housing provides a strong, clean sound ideally suited for all audio presentations. The composite construction combines strength and durability with improved damping. Secret Sound is available with a choice of three parabolas: clear, black or white.
