QD-Bass Technology Allows Free Placement |
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. Also, most other systems use circular cones, but by radiating in four directions to avoid the legs of the cabinet, QD-Bass reduces turbulence caused by reflection from the legs. Changing the height of the square pyramid varies the acoustic load, permitting relatively simple high-cut adjustment and improved bandpass properties. The QD-Bass system provides extraordinary power and smooth frequency response from an extremely compact unit. It also allows greater freedom of placement, since the sound radiates with equal effectiveness in all directions. |
Advanced YST II for Awesome Deep Bass |
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 the previous system. 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. |
PWM Digital Drive High Efficiency Amplifier |
The YSTSW325 delivers high power outputs at deep bass levels, with excellent stability and low power consumption, even with their compact cabinets. This is made possible by a highly efficient power amplifier. The power 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 consumption and heat production. It does not require an output filter coil, resulting in extremely low noise and distortion. High speed transient response is also excellent. |
Extra Features |
The Linear Port on the YSTSW325 provides smooth bass response during playback and minimizing 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 YSTSW325 is also environmentally friendly. Internal parts and circuit boards do not contain lead, which is often used in other subwoofer brands, and is harmful to the environment. The YSTSW325 also has a low-power standby mode, in which power consumption is only 0.5 watts. |
