  • Notes

  • The Yamaha Natural Sound Active Servo Processing speakers are specifically designed for use with a Yamaha Active Servo Processing amplifier, such as the Yamaha AST-A10 which not only supplies an amplified signal to drive the speakers, it also controls the operation of the speakers directly. The Active Servo Processing Speakers feature specially tuned enclosures for effective operation even with the smallest amplitude voice coil oscillations offering a linear response extending down to the lower bass frequencies (28Hz). An Active Servo Processing Cartridge AST-KS1 is supplied with the speakers, this is inserted into the cartridge holder on the front of the power amplifier before use.
