Abstract
An audio transducer for use in a loudspeaker system. The transducer includes a rigid base, a pair of flexible, curved diaphragms and each diaphragm having a distal end and a proximal end. The curved diaphragms form hemi-cylindrical lobes being substantially tangent to one another at their proximal ends and are attached to energy absorbent dampers at their distal ends. The transducers can be employed in a line array as part of the loudspeaker system as well as some of the transducers facing forward while others rearward and, in doing so, their amplitudes and phases can be adjusted for fine tailoring the geometric coverage of acoustic energy radiating from the loudspeaker system.
