Power and Performance

The YSTSW1500 uses Yamaha’s Advanced YST and QD-Bass technology to deliver exceptionally crisp, clean, powerful bass all the way down to 16Hz. The YSTSW1500 uses an extremely efficient, high-power built-in amplifier, while extra-long stroke drivers provide outstanding power with low distortion. The YSTSW1500 also introduces a Dual-Bias system with a 100mm (4") diameter voice coil for the ultimate in power and performance.

Advanced YST

Yamaha’s patented Advanced Active Servo Technology (Advanced YST) generates incredible bass from small speaker enclosures. Advanced YST is the ideal method of combining amplifiers and speakers for maximum performance. This system’s advanced negative impedance converters intelligently adjust the negative impedance generation as the speaker moves, creating a hard, rigid cone that prevents deep resonant waves from leaking out of the speaker cone. This means the full power of the waves is forced out through the air port, resulting in clear, powerful bass.

QD-Bass Technology

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.
