Japanese Electrostatic Pioneers From 1938

Stax, founded in 1938, is a Japanese company that makes high-end audio equipment. Twenty-two years later, in 1960, Stax released their first electrostatic earspeaker, the Stax SR-1. Over the following thirty-six years, Stax produced a variety of amplification, earspeaker, tonearm, CD player, DAC, phono cartridge and loudspeaker products.

Stax is best known for its electrostatic and electret headphones, which they call earspeakers. Electrostatic headphones work similarly to electrostatic loudspeakers but on a smaller scale. In 1995, fifty-seven years after the company’s foundation, it became insolvent. The company was revived in 1996 as the new STAX company. In December 2011, Chinese loudspeaker manufacturer Edifier announced the acquisition of 100% equity in Stax.
