Abstract: A compact loudspeaker having a vertically oriented cylindrical housing supporting a relatively high frequency sound driver and a relatively low frequency sound driver. The high frequency driver closes the top of the housing, and is oriented to project sound upwardly. The low frequency driver is contained within the housing such that it divides the housing into upper and lower sound propagating chambers. The low frequency drive projects sound downwardly into the lower chamber. The lower chamber is closed at the bottom of the housing by a bottom plate. The lower chamber has a port communicating to the exterior of the housing. A crossover network is mounted to the bottom plate. Input terminals are located in the lateral surface of the housing. The interior of the housing is lined with acoustic padding for sound damping. The exterior of the housing is covered with a grille cloth, which in turn is covered with screen material. Decorative trim rings cover the upper and lower edges of the grille cloth and screening.

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.
