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 &# 39 ; 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 .
