Abstract

A transducer porting assembly (100, 200, 300) includes a transducer (102) mounted within a housing (502) and an adjustable iris diaphragm (104) formed within the housing and aligned with the transducer. A selectable control (506) allows the audio response of the transducer (102) to be controlled by a user so as to accommodate various acoustic environments (508).
