About Yamaha YST-SW315

Ideal for generating the tight, visceral bass that is so vital to the home theater experience, the YSTSW315 10-inch, Performance Series, Powered Subwoofer will complement any system configuration. In conjunction with smaller, bookshelf-type speakers, it extends the system capability for true full-range frequency response.

With large, floor-standing speakers, a subwoofer helps shoulder the burden of reproducing low-frequency information. Port-tuned and slot loaded, it utilizes long-throw woofers and powerful built-in amplifiers for room shaking reproduction, crushing power and quick, tight bass. Standard features include high and low level inputs, variable level and frequency controls, phase control and auto on/off sensing.

Yamaha YST-SW315 Features

  • Advanced Active Servo Technology: Yamaha's Advanced Active Servo Technology is a complementary amplifier/speaker system utilizing negative impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass.
  • 10" Driver And 250 Watt PWM Amplifier: High amplifier power assures enough power to deliver shattering movie theater-like bass effects, and the down firing 10-inch long stroke cone driver translates the power into clear bass sound.
  • BASS Selector: Yamaha's BASS (Bass Action Selector Switch) tailors the sub's output for video or music at the touch of a switch.
  • Yamaha QD-Bass Technology: A Yamaha technology that uses a down firing driver to radiate the bass output more efficiently. Sound is radiated in all directions for greater impact.
  • Magnetic Shielding: The subwoofer is magnetically shielded so it can be placed near a TV monitor or receiver without degrading the picture.
  • Continuously Variable High-Cut Filter: The user adjustable continuously variable high-cut filter sets the highest frequency the subwoofer will deliver. It can be set anywhere from 40 to 140 Hz.
  • Volume Control: The volume control permits the perfect matching of the sub's output to the overall volume of the system.
  • Signal Sensing ON/OFF: For convenience, the YST-SW315 has a signal sensing circuit.When the subwoofer detects an audio signal, it turns its power on. When it senses no signal for several minutes, it shuts itself off.
  • Phase Normal/Reverse Switch
  • Makes it easy to phase the subwoofer with the other speakers in your system.
  • Dual Inputs: Two sets of inputs allow the versatile subwoofer to accept either line level or speaker level input signals.
  • Heavy Duty Speaker Terminal: Yamaha's three-way speaker terminals accept banana plug and a variety of other connectors, as well as speaker wire.
  • Black Ash Finish: Handsome black ash finish blends in with room decor and complements many furnishing styles.
  • Rigid Cabinet construction: The YST-SW315's cabinet is constructed of thick MDF to increase rigidity and reduce vibration and resonance.
