Experience dynamic bass that will bring out the full potential of your digital music and movie sources. The Yamaha YST-SW800 10 Digital Pro Series subwoofer delivers bass down to 18 Hz with up to 1,000 watts of power. The YST-SW800 uses technologies like Yamaha's Active Servo Technology (Advanced YST) and Quatre Dispersion Bass (QD-Bass) to deliver exceptionally crisp, clean, powerful bass. It has an extremely efficient, high-power amplifier and uses an extra-long-stroke driver to provide outstanding power with low distortion. Advanced YST is a unique system in which the speaker and amplifier work together to cancel out impedance so the speaker unit has a perfectly linear motion. Advanced YST helps to ensure the highest levels of sound pressure and overall performance. The key to its success is a Helmholtz resonator--a small port in the speaker cabinet. The cabinet volume and port size are scaled to an exact ratio, which magnifies small-amplitude input signals without distortion. The QD-Bass system provides extraordinary power and smooth frequency response. It also allows greater freedom of placement for the sub, since the sound radiates with equal effectiveness in all directions. QD-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' subwoofers) negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit.
The YST-SW800 delivers high power outputs at deep bass levels, with excellent stability and low AC power consumption, even with its compact cabinet. The power amplifier achieves superior conversion efficiency by supplying maximum power (minimizing power loss) from the power transistors according to the actual output level during playback. It requires no output filter coil, which means no added noise or distortion. The sub's high-speed transient response is also excellent.
