Introduction Features

This subwoofer system employs Advanced Yamaha Active Servo Technology II which Yamaha has developed for reproducting higher quality super-bass sound. (Refer to page 6 for details on Advanced Yamaha Active Servo Technology II) This super bass sound adds a more realistic, theater-in-the-home effect to your stereo system. The slim design matches the interior of your home.

Supplied accessories

Please conrm that the following item is included in the package.

Subwoofer cable

System connector cable ( U.S and CANADA model only )
Positioning the subwoofer
It is recommended to place the subwoofer on the outside of either the right or the left front speaker. (See g. A.) The placement shown in g. B is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as shown in g. A. Note: There may be a case that you cannot obtain enough super-bass sounds from the subwoofer when listening in the center of the room. This is because standing waves have been developed between two parallel walls and they cancel the bass sounds. In such a case, face the subwoofer obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls.

Advanced Yamaha Active Servo Technology II
In 1998, Yamaha brought to the marketplace speaker systems utilizing YST ( Yamaha Active Servo Technology ) to give powerful, high quality bass reproduction. This technique uses a direct connection between the amplier and speaker, allowing accurate signal transmission and precise speaker control. As this technology uses speaker units controlled by the negative impedance drive of the amplier and resonance generated between the speaker cabinet volume and port, it creates more resonant energy (the air woofer concept) than the standard bass reex method. This allows for bass reproduction from much smaller cabinets than was previously possible. Yamahas newly developed Advanced YST II adds many renements to Yamaha Active Servo Technology, allowing better control of the forces driving the amplier and speaker. From the ampliers point of view, the speaker impedance changes depending on the sound frequency. Yamaha developed a new circuit design combining negative-impedance and constant-current drives, which provides a more stable performance and clear bass reproduction without any murkiness.

YST-FSW100 Advanced YST II Subwoofer
Slim Design The YST-FSW100 has a slim, elegant design that will perfectly match thinline home theater components and plasma monitors or flat-screen TVs. Advanced YST II for Awesome Deep Bass Yamaha's newly developed Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constantcurrent 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.
New Half Pipe Port The subwoofer also employs a new design feature called the Half Pipe Port, which further smoothes bass response and minimizes extraneous noise. Large (16cm; 6.5) Driver with Magnetic Shielding 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. Environmentally Friendly Internal parts and circuit boards do not contain lead, which is often used in other subwoofer brands, and is harmful to the environment.
Effect of New Half Pipe Port
Advanced YST produces rich bass sound, and the addition of a Linear Port reduces extraneous noise for even higher quality.
A semicircular Half Pipe Port provides the benefits of full 180 dispersion when placed against a wall, compact design and minimal extraneous noise for high sound quality.

Advanced YST Concept

The effectiveness of Advanced YST (Yamaha Active Servo Technology) is based upon two principles: the Helmholtz Resonator and negativeimpedance drive. Active Servo Processing speakers reproduce the bass frequencies through an air woofer, which is a port or opening in the speaker cabinet. This port is used instead of, and performs the functions of, a conventional woofer. Low amplitude signals inside the cabinet can, due to the Helmholtz Resonance principle, be output from this port as high amplitude waves if the design is such that the size of the port and the volume of the cabinet are in a certain proportion. In addition, the wave amplitudes inside the cabinet must be precise and of sufficient power, in order to overcome the load presented by the air within the cabinet. This is accomplished by employing an amplifier that is capable of supplying special signals. If the electrical resistance of the voice coil could be reduced to zero, the movement of the speaker unit would become linear with respect to signal voltage. To achieve this, a special negative-impedance output drive amplifier is used, so the impedances cancel out and become zero. By employing negative-impedance drive circuits, the amplifier is able to generate precise, low-amplitude low frequency waves with superior damping characteristics. These waves are then radiated from the cabinet opening as high amplitude signals. This amplifier/speaker combination is capable of reproducing an extremely wide range of frequencies with excellent sound quality and low distortion. The Advanced YST takes this concept a stop further by adopting Advanced Negative Impedance Converter (ANIC) circuits. These circuits allow the converter to dynamically vary in order to select the optimum values for speaker impedance variation. With these new circuits, Advanced Yamaha Active Servo Technology provides more stable performance and higher sound pressure levels than the former system, resulting in more natural and energetic bass reproduction.
