Yamaha YST-SW216BL Advanced YST II, Front-Firing Active Subwoofer - Black

The YST-SW216BL Active Subwoofer sets the standard for subwoofers in this class with high dynamic power and low-noise performance thanks to Advanced YST II, a Linear Port, Front-firing design, plus many other sophisticated features. Advanced YST II combines negative impedance and constant-current principles to drive the speaker cone with even tighter control than before. This system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response for more natural and energetic Bass reproduction. /10-Inch Long-Stroke Cone Driver With Magnetic Shielding / Selectable high-cut filter Dynamic Power: 100 Watts/ Output Power: (5 ohms, 100Hz, 10%THD) - 50 watts / Frequency response 25-180 Hz Dimensions (WxHxD):13-3/8 x 13-3/8 x 15-3/16 inches / Weight: 28.7 lbs
