For sale quality YAMAHA YST-SW 325 Powered/Active Subwoofer in black colour in very good and clean condition and in full working order. Great quality and superb performance with Deep and powerful BASS because of QD-Bass (Quatre Dispersion Bass) technology to improve the performance plus the option to change performance between Movies and Music. The subwoofer will be perfect for average or large living room in Multi channel Home Cinema Configuration or Stereo System. All of the regulations and connectors like power switch, volume control and crossover control, all the inputs/outputs and Auto Stand by, Phase control plus speakers connectors are located on the back panel in two separate sections. Some scratches on the case and one 2″ chip on the back left top corner – please see all 12 pictures for more details. Power lead attached to the unit. Extra free quality 5m long subwoofer’s cable included. Any questions please ask.
One of the few sub which, thanks to good bass control, works well in stereo music sets. This does not mean that fans of home theater effects will be disappointed – we have a magic button “Movie” which radically changes the nature of the generated bass into a cinematic sound.
Great Prdouct Features Include: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.
Yamahas 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. Yamaha’s Advanced YST and QD-Bass Technologies Give This Top Class Subwoofer an Outstanding Combination of Power, Depth and Clarity.
