Yamaha's YST-SW225B subwoofer combines 150W of dynamic power with exclusive QD Bass and Advanced YST II technology to provide top-class sound quality. QD-Bass (Quatre Dispersion Bass) technology uses down-firing drivers with square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions. The reflective plates (not used in competitors' down-firing subwoofers) negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit. Unlike most other systems, QD-Bass reduces turbulence by radiating in four directions to avoid reflection from the legs of the cabinet. This means that the YST-SW225B generates extraordinary power and smooth frequency response from an extremely compact unit and allows greater freedom of placement because the sound radiates with equal effectiveness in all directions. Yamaha's newly developed Advanced YSTII (Yamaha Active Servo Technology II) combines negative impedance and constant-current principles to drive the speaker cone with even tighter control than in previous models. 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-SW225B has a highly efficient power amplifier, enabling it to deliver high power outputs at deep bass levels, with excellent stability and low power consumption. It also delivers stable power output with high efficiency while minimizing power consumption and heat production. Because it does not require an output filter coil, both noise and distortion are extremely low. The linear port provides smooth bass response during playback and minimizes extraneous noise. The BASS (Bass Action Selector System) function lets you switch between Movie and Music modes, providing the optimum frequency response in each case. The internal parts and circuit boards of the YST-SW225B do not contain lead, which is often used in other subwoofer brands, and is harmful to the environment. It also has a low-power standby mode, in which power consumption is only 0.5W.| Product Description | Yamaha YST SW225B - subwoofer | | Product Type | Subwoofer | | Dimensions (WxDxH) | 29 cm x 34.9 cm x 35 cm | | Weight | 11.5 kg | | Speaker Type | Active | | Nominal (RMS) Output Power | 120 Watt | | Max Output Power | 150 Watt | | Response Bandwidth | 28 - 200 Hz | | Audio Amplifier | Integrated | | Connectivity Technology | Wired | | Speaker System Details | Subwoofer - 120 Watt - 28 - 200 Hz - 5 Ohm | | Colour | Black | | Power | AC 230V ( 50 Hz ) |
