Developed by Yamaha, 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 the previous version. Using advanced negative impedance converter (ANIC) circuitry, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate bass response, not to mention greater sound quality.

The gently rounded shape with a sloping front surface presents a sleek and stylish appearance. Designed to be discreet, it is sure to look great in a living room or home theater room. Available in black, walnut and white so you can choose the model that best matches your other speakers.
