This Yamaha Slim Digital Pro Series Subwoofer offers 250 high-efficiency watts - enough power to   deliver shattering, movie-theater-like bass effects. Full enjoyment of   Dolby Digital and DTS surround sources requires deep, clear bass. This   is especially true with 5.1- and 6.1-channel sound, because the ".1"   channel is dedicated to the bass frequencies. That means you not only   need a subwoofer, but a high-power subwoofer capable of handling   extremely low frequencies. This Yamaha YST-SW315's down-firing 10-inch driver   translates power into clean bass sound, and the YST-SW315 boasts a   frequency response of 20 to 160 Hz (-10 dB at the extremes of the   range).

This Yamaha YST-SW315 delivers high power at deep bass frequencies,   with excellent stability and low power consumption. This is made   possible by the sub's highly efficient PWM (pulse-wave modulation)   digital-drive power amplifier. The amplifier achieves superior   conversion efficiency by minimizing power loss from the power transistors. It delivers stable audio power while minimizing AC power consumption and heat production. As it requires no output filter coil,   it's extremely quiet with low distortion.

Yamaha's patented Advanced Active Servo Technology (Advanced YST) generates incredible bass from small speaker enclosures. This system uses negative-impedance feedback in the amp and a Helmholtz resonator in the speaker to provide   strong and accurate bass.

The rotary volume control permits the perfect   matching of the sub's output to the overall volume of the system. This Yamaha model 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.

QD-Bass (Quatre Dispersion Bass)   technology uses a down-firing driver with square, pyramid-shaped   reflective plates to radiate sound efficiently in four horizontal   directions. The reflective plates (not used in other brands' down-firing   subwoofers) negate any effects caused by the floor surface and reduce   resonance between sound waves reflected from the floor and the unit. QD-Bass also grants greater freedom of placement, since the sound radiates with equal effectiveness in all directions.

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 lowest reproducible frequency of other speakers in the system and the room's acoustics for a seamless   presentation.

Yamaha's BASS (Bass Action Selector Switch) tailors the sub's output for video or music at the touch of a switch. Two sets of inputs let the sub accept either line- or  speaker-level inputs, while a handy phase normal/reverse switch makes it easy to phase the subwoofer with the other speakers in your system.

Three-way speaker terminals accept banana plug and a variety of other connectors, as well as speaker wire, and the YST-SW315's thick, rigid  MDF cabinet reduces vibrations and resonance. The speaker's handsome   black-ash finish blends in with room decor and complements many furnishing styles, and it's magnetically shielded so you can place it  near a TV or computer monitor without degrading the picture.
