A compound driver acoustic transducer (100). A frame (102) supports a motion generator (103) to one side of two diaphragms (104, 105). An intermediate diaphragm (105) is continuous adn is driven by the motion generator. The intermediate diaphragm forms a closed volume (110) with a solid portion (130) of the frame that opens into a central opening (107) through the other, open diaphragm. An axially rigid coupling (106) connects the two diaphragms so they operate in unison.
