An Electrostatic Loudspeaker Development
The idea of bringing electromechanical forces of transduction to bear directly on the transmitting medium spurred many pre-high-fidelity experimenters to extensive attempts to harness the electrostatic mechanism of transduction to the design of loudspeakers. Early attempts were not notably successful, either in this country or abroad. The advent of new materials and techniques and the growing awareness of, and demand for, fidelity in the reproduction of recorded music and other program material have provided both the incentive and the means for a renewal of effort. One of the results of this effort is the Janszen electrostatic loudspeaker, which is designed for use with two-way systems. High efficiency is obtained over a wide frequency range, which extends from below 1000 cps to above 20 kc. The membrane used in its building-block elements is so light that, over most of its frequency range, it functions as an imaginary boundary in the air. The axial pressure response, therefore, is extremely smooth. The unit operates from the 8-ohm or 16-ohm output of any amplifier, and contains its own bias supply. Maximum power output is 0.5 acoustic watt.
