Advanced YST II for awesome deep bassYamaha's Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constant-current principles to drive the speaker cone with even tighter control than previously. Using Advanced Negative Impedance Converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response, not to mention higher sound pressure levels, for more natural and energetic bass reproduction. Linear portAdvanced YST II produces rich bass sound, and the addition of a linear port reduces extraneous noise for even higher quality. The linear port helps to ensure smooth bass response, while minimizing extraneous noise.
