YST (Yamaha Active Servo Technology) to give powerful, high quality bass reproduction. This technology uses a direct connection between the amplifier and speaker, allowing accurate signal transmission and precise speaker control. As this technology uses speaker units controlled by the negative impedance drive of the amplifier and resonance generated between the cabinet capacity volume and port, it creates more resonant energy (the “air woofer” concept) than the standard bass reflex method. This allows for bass reproduction from much smaller cabinets than was previously possible. Yamaha’s newly developed Advanced YST II adds many refinements to Yamaha Active Servo Technology, allowing better control of the forces driving the amplifier and speaker. From the amplifier’s point of view, the speaker impedance changes depending on the sound frequency. Yamaha developed a new circuit design combining negative-impedance and constant-current drives, which provides a more stable performance and clear bass reproduction without any murkiness.
