PHASS is a car Audio brand owned by FT trading co., LTD in Japan. The development of PHASS car Audio can be traced back to the 1990s. Shogo kurokochi, the founder of PHASS, entered the car and audio industry in the spring of 1994 when he began developing the RE2 amplifier. In 1996, the RE2 amplifier was completed and PHASS company was established. A year later, to perfect the RE2 amplifier, the hi-end speaker made of aluminium-nickel-cobalt magnet material was made by Japanese craftsmen at every step of the production process.
