Abstract
Recent progress in piezoelectric loud speakers for theater use, including a new unit for upper registers, is described. Frequency-response characteristics of this unit alone and in combination are discussed and demonstrated. The character of the load upon the output circuit, and its effect upon the efficiency and the production of satisfactory response in the low and high registers, are discussed.
