ABSTRACT:
A coaxial speaker assembly (10) with reduced sound distortion, sound time delay, and polar response distortion. The coaxial speaker assembly (10) includes a high-frequency speaker system (16) mounted coaxially with and fitting within a lower-frequency speaker system (14). A baffle (50) is secured to a diaphragm (48) of the high-frequency speaker system (16). A step-down ledge (52) is circumferentially positioned adjacent to the baffle (50) and extends outwardly therefrom. A portion of the sound waves emanating from the high-frequency diaphragm (48) are reflected off the step-down ledge (52).
