Yamaha YST-RSW300BL Advanced YST II Down-Firing Active Subwoofer
Product Description
Yamaha YST-RSW300BL Advanced YST II Down-Firing Active Subwoofer is a high performance subwoofer with Yamaha’s latest technologies, including PWM Digital Drive Amplifier, Advanced YST II, Linear Port and front-firing design resulting in dynamic power of 270W and incredible sound clarity. 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 YST-RSW300 delivers high power outputs at deep bass levels, with excellent stability and low power consumption, due to a highly efficient PWM Digital Drive amplifier. The amplifier achieves superior conversion efficiency by supplying maximum power (minimizing power loss) from the power transistors according to the output level. It delivers stable power output with high efficiency while minimizing power, resulting in extremely low noise and distortion. High speed transient response is also excellent. The subwoofer features a high performance front-firing, active design. It provides power and detailed, accurate reproduction in a compact unit. Capable of handling 270W of dynamic power, this subwoofer ensures that you hear all bass sounds, even the loudest short bursts, with fast attack and total clarity. The Linear Port provides smooth bass extraneous noise. The powerful, long-stroke cone driver is exceptionally large (25cm; 10) for this class of subwoofer. Magnetic shielding means there is no distortion-causing interference when used near a TV or other monitor.
