Abstract
A corner mounted sound reproduction speaker apparatus is adapted to be mounted in a corner space defined in part by a pair of intersecting vertical surfaces and includes a hollow enclosure housing having a base and a pair of imperforate side faces adapted to engage and to overlie the respective ones of the pair of vertical surfaces. The enclosure housing also includes an inclined front face of a generally triangular shape. Speaker devices are mounted within the interior of the enclosure housing behind the front face and are adapted to be energized by a sound reproduction system, the speaker devices having a response in the range of about 20 cycles per second and about 20,000 cycles per second. The plane of the base is disposed at an angle relative to the axis of radiation of the speaker devices, and the angle is an angle between about 35.degree. and about 50.degree. so as to enable a pair of such speaker units to be employed in opposite corners of a room to produce a stereo effect throughout the room.
