ABSTRACT:
A room audio speaker system for use in combination with at least one room boundary surface, the speaker comprising an enclosure having a closed end wall for placement closely adjacent the room boundary surface and a second wall extending away from the end wall and providing a front edge and a rear edge, the latter forming a boundary with the end wall. Direct radiator audio reproducer means are provided generally flush mounted generally parallel to a portion of the exposed surface of the second wall. The included angle between the end wall and that second wall portion is no more than about 90.degree.. The distance along the second wall from the center of the reproducer means to the rear boundary edge is not more than one-half the smallest outside dimension of the second wall and the closed end wall is free from any audio reproducer means.
