Yamaha KS-SW100 Keyboard Subwoofer

Developed by Yamaha, the 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) 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 quality.

The gently rounded form with a slanted front surface presents a stylishly elegant appearance. Designed to be unobtrusive, It’s sure to look beautiful in a living room or home theatre room. Offered in black, walnut and white, so you can choose the model that best matches your other speakers.
