Abstract
A coaxial speaker system that minimizes detrimental sound wave reflections from its high frequency speaker. The coaxial speaker system includes a high frequency speaker coaxially mounted within a low frequency speaker. The high frequency speaker includes a sound reproducing membrane, a voice coil assembly and magnet assembly for actuating the sound reproducing membrane in response to an electrical audio signal, and optionally a wave guide horn for directing sound waves produced by the sound reproducing membrane. The wave guide horn has a throat disposed adjacent the sound reproducing membrane and a mouth disposed opposite the throat. The low frequency speaker also includes a sound reproducing membrane assembly and a voice coil assembly and magnet assembly for actuating the sound reproducing membrane assembly in response to an electrical audio signal. At least a portion of the low frequency speaker sound reproducing membrane assembly is positioned adjacent the mouth of the wave guide horn (or adjacent the outer edge of the high frequency speaker sound reproducing membrane when no horn is provided) to inhibit the detrimental effects of sound waves produced by the high frequency speak…
