The Yamaha YST-FSW050 Subwoofer: New Slim Design for Compact Home Theater Systems
This new shaped subwoofer features Yamaha's latest technologies, including Advanced YST II, Linear Port and down-firing Active design, and produces clean, distortion-free bass to add satisfying weight to your movies and music. The YST-FSW050 is an ideal match for surround-sound sound bar systems (like Yamaha's Digital Sound Projector Series) and micro component systems--any place you need a big punch from a smaller package.
Advanced YST II and Down-Firing Active Subwoofer
Rack-Mountable Design Matches Speakerbar Systems and Micro Component Systems

reduces cabinet noise for clarity even at high volumes
The typical subwoofer box is not a good aesthetic match for a slim front surround system such as a Yamaha Digital Sound Projector. So Yamaha created a new design for the YST-FSW050. Much slimmer than normal subwoofers, it will fit neatly in a rack below the surround system like Yamaha's Digital Sound Projector series, and matches well with micro component systems such as Yamaha's PianoCraft series. Of course, the compact, rack mountable design saves space as well. Down-Firing Active Design
This subwoofer employs a high performance, down-firing active design. Even though compact, it delivers impressive bass power and accurate sound reproduction. The down-firing design radiates the sound efficiently in all directions. Linear Port
The Linear Port provides smooth bass response and minimizes extraneous cabinet noise to eliminate the "box buzz" common to smaller subwoofers. It also serves to boost the sound output from this compact subwoofer, so you can fill any room with tight, punchy bass. Dynamic Power
Capable of handling high dynamic power, the YST-FSW050 subwoofer ensures that you hear all bass sounds, even the loudest short bursts, with fast attack and total clarity.
Advanced YST II Brings You Super Bass

to create smooth bass with fast attack
The effectiveness of Advanced YST II (Yamaha Active Servo Technology II) is based upon two principles: the Helmholtz Resonator and negative-impedance drive.
How does it work? Advanced Yamaha Active Servo Technology (Advanced YST) uses an Active Servo Processing amplifier circuit to achieve zero impedance so the speaker unit has a more linear motion, resulting in tighter bass reproduction and minimizing distortion because everything in the subwoofer moves together smoothly.
In Advanced YST II, an Advanced Negative Impedance Converter enables the speaker cone to be driven with even tighter control--it can dynamically adjust in order to select the optimum values for speaker impedance variation. The result is more stable and accurate low range response, as well as higher sound pressure levels, for more natural and energetic bass reproduction.

New shape subwoofers with Yamaha's latest technologies, including Advanced YST II, Linear Port and down-firing design plus best matching for front surround systems and micro component systems. 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.
