Abstract
By providing a spherically shaped loudspeaker and/or closure containing one or more drivers or speaker motors, mounted in cooperative association with a uniquely constructed reflector, a loudspeaker system is achieved which controls and shapes the ultimate acoustical waveform produced thereby. The system of present invention controls and distributes the acoustical energy of the driver, while shaping the acoustical energy field in a true hemispherical pattern, within the system's power bandwidth. By employing the present invention, the point of summation of the hemispherical pattern is approximately eight times the diameter of the reflector, thereby achieving the desired hemispherical polar coverage patterns.
