YST-SW1500

Digital Pro Series Subwoofer

The YST-SW1500 uses Yamaha’s Advanced YST as well as brand new technologies such as QD-Bass to deliver exceptionally crisp, clean, powerful bass all the way down to 16Hz. Delivering 1500W of power; the YST-SW1500 has an extremely efficient, high-power amplifier built in, and uses an extra-long stroke, drivers that provide outstanding power with low distortion. The YST-SW1500 also introduces a Dual-Bias system with a 100mm (4") diameter voice coil for the ultimate in power and performance.

High-Efficiency Power Amplifier and Power Supply
The YST-SW1500 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 highly efficient power amplifier technology and a new power supply. 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.

The YST-SW1500 uses a new power supply that features superior load characteristics, minimal noise, higher efficiency and greater stability. Switching power supplies, commonly used in audio and other consumer products are small and efficient, but suffer from noise problems, requiring additional components to solve. This power supply, however, holds the voltage and current levels to zero while the device turns on and off. This reduces noise to 1/30 of conventional switching power supplies. Power loss during switching is also reduced, enabling incredibly high power conversion efficiency. Other advantages of this power supply include superb stability against power load fluctuations, large capacity, low impedance and silent operation.

Extra-Long Stroke, Pure Spruce Dual-Bias Drivers
These new drivers provide outstanding power with low distortion and are superior to conventional drivers for a number of reasons. Due to the use of a vertically aligned, dual magnetic circuit structure with 100mm (4") diameter voice coils; they are able to handle extremely high input power in a compact unit, with low radial distortion. Additionally, the vertically symmetrical gap magnetic flux density distribution reduces second harmonic (asymmetrical) distortion. Double spider construction also aids in handling high bass inputs without cone deformation. And the strong die cast frame firmly anchors the entire body including the magnetic circuit, guaranteeing a structure that will not fail under powerful forces.
