Yamaha YST-FSW100

Yamaha YST-FSW100 ... energetic bass reproduction in a slim box.

The YST-FSW100 has a slim, elegant design that will perfectly match thin home cinema components and plasma monitors or flat-screen TVs. Yamaha's newly developed 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. The subwoofer also employs a new design feature called the Half Pipe Port, which further smoothes bass response and minimizes extraneous noise. The powerful, multi-range driver is exceptionally large (16cm; 6.5") for this class of subwoofer. Magnetic shielding means there is no distortion-causing interference when the speaker is placed near a TV or other monitor.
