[feature] Horns and direct-radiating systems have provided the basis for sound reinforcement for more than a century. Both technologies have benefited from engineering and manufacturing improvements as well as demands for pushing the performance envelope. Trends of fashion have often intersected with engineering development, economics, and even marketplace opportunism. A survey tutorial of the significant developments in transduction, signal transmission, and system synthesis is presented here and discussed in historical perspective.
