ABSTRACT:
A speaker propagating sound waves in the manner of a point source. The speaker includes high, medium, and low range drivers vertically arranged within a vertically arranged tubular support member having sound escape openings in its lateral wall. The high and medium range drivers project sound upwardly, and the low range driver projects sound downwardly. The speaker has a truncated obeliskoid housing including a chamber disposed below the low range speaker. This chamber is muffled to absorb non-coherent sound, and has a vertical air tube for managing air flow within the chamber and conducting sound waves downwardly from the housing. The high range driver is exposed above the housing, so that sound projects upwardly therefrom. Sound produced by the medium range driver passes through the openings in the tubular support member. The housing is supported on casters for mobility.
