Ideal for generating the tight, visceral bass that is so vital to the home theater experience, the Yamaha YST-SW315 10" 250W 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 a long-throw woofer and powerful built-in amplifier 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.
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 250W PWM Amplifier
High amplifier power assures enough power to deliver shattering theater-like bass effects, and the 10" down-firing, long-stroke cone driver translates the power into clear bass sound. The PWM digital drive amplifier is efficient and stable. The YST-SW315 has a frequency range of 20 to 160 Hz.
Tailored for Movies and Music
Yamaha's BASS (Bass Action Selector Switch) tailors the sub's output for video or music at the touch of a switch.
QD-Bass Technology
QD-Bass 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. For instance, if the filter is set at 75 Hz, only frequencies 75 Hz or below will be delivered by the subwoofer. This allows the sub's output to be matched to the other speakers in the system and the room's acoustics for a seamless presentation.
Volume Control
The volume control permits the perfect matching of the sub's output to the overall volume of the system.
Signal Sensing
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
This 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.
Three-Way Speaker Terminals
Yamaha's three-way speaker terminals accept banana plug and a variety of other connectors, as well as speaker wire.
Rigid Cabinet Construction
The YST-SW315's cabinet is constructed of thick MDF to increase rigidity and reduce vibration and resonance.
