Stable and Accurate Low End
Developed by Yamaha, YST II (Yamaha Active Stereo Technology II) combines negative-impedance and constant current principles to drive the cone with precise control. A more stable and accurate low end representation is achieved through YST II. Advanced Negative Impedance Converter (ANIIC) circuits help maintain excellent linearity to produce higher sound quality. With all of these technologies combined the end result is a subwoofer that is clean, tight, and reproduces the low end signal accurately.
