Abstract: A reflex type speaker enclosure integrally formed of ceramic material having a shell of hemispheroidal configuration and having an inturned speaker mounting flange adjacent the equatorial plane. The enclosure is adapted to be suspended by structure extending through an aperture in its apex. The flange forms a central, relatively large speaker aperture, and a plurality of circumferentially spaced, relatively small acoustic ports intermediate the shell and aperture. The radially inner edge of the flange is notched at the speaker aperture to permit placement of a speaker assembly into the interior of the hemispheroidal shell and allow insertion of suitable fasteners therethrough to secure the speaker assembly to the inwardly facing side of the flange portion.
