ABSTRACT:
A sound imaging system preferably including two enclosures each comprising a truncated conical base unit and a truncated conical upper unit supported above and spaced apart from of the base unit, and containing a bass driver and composite midrange and high frequency drivers. The bass driver is oriented horizontally at the top of the base unit, and the sound energy produced therefrom is reflected by a conically shaped acoustic lens or defector depending from within the interior of the upper unit directly above the bass driver, such that the sound energy is reflected downwardly along and between the spaced apart truncated conical walls of the upper unit and base unit and emanates radially therefrom in all directions. The composite midrange and high frequency drivers are supported at the top of the upper unit on a crown structure having a plurality of vertical legs defining a platform oriented approximately 20.degree. relative to horizontal.
