Yamaha YST-FSW100 Active Subwoofer
YST-FSW100
Advanced YST II Subwoofer
Perfectly matched for the plethora of thin home cinema components such as Plasmas, Flat Screen TV’s and Yamaha’s very own Digital Sound Projectors, the YST-FSW100 is a great solution for people wanting energetic bass reproduction in a slim box.
Some of the YST-FSW100’s great features;
The YST-FSW100 has a slim, elegant design that will perfectly match thin home cinema components and plasma monitors or flat-screen TVs.
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 previously. Using Advanced Negative Impedance Converter (ANIC) circuits, this system dynamically optimises 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.
The subwoofer also employs a new design feature called the Half Pipe Port, which further smoothes bass response and minimizes extraneous noise.
The powerful, multi-range driver is exceptionally large (16cm; 6.5”) for this class of subwoofer. Magnetic shielding means there is no distortion-causing interference when the speaker is placed near a TV or other monitor.

Yamaha YST-SW325 Active Subwoofer
YST-SW325
Advanced YST II & QD-Bass Subwoofer
Yamaha’s Advanced YST II and QD-Bass Technologies Give This Top Class Subwoofer an Outstanding Combination of Power, Depth and Clarity. Designed to Match the 325 A-PMD Series Speakers.
Some of the YST-SW325’s great features;
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.
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 previously. 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.
The YST-SW325 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.
