Janszen Laboratory Inc.
In 1954, Arthur A. Janszen took control of the Magnetic Amplifier Corp. of Waltham and moved it to Cambridge under the name of Janszen Laboratory Inc. Janszen, a researcher at Harvard's Acoustics Research Laboratory, had recently been awarded a patent for the first commercially feasible electrostatic speaker system. The company's first commercial product was released in 1955, the very successful JansZen Model 130, a tweeter (high-pitch speaker) array. Janszen then followed up with the development of the first full-range electrostatic speaker array, which was released in 1959. That same year Janszen's company merged with the KLH Research and Development Corporation, of which he became Vice-President. KLH continued production of what was considered to be the finest ever sound reproduction system, now called the KLH Model 9.
