Yamaha YST-SW015 QD-Bass Powered Subwoofer
Yamaha Updated: 2008-08-31 RSSYamaha's Advanced YST II and QD-Bass Technologies gives this subwoofer great power, depth and clarity.
Advanced YST
Advanced Yamaha Active Servo Technology (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.
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 negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit.
