Yamaha's YST-SW315 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. The 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).

The 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.

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. Most other systems use circular cones, but the YST-SW315 avoids firing sound into the legs of the
cabinet by radiating in four directions. Changing the height of the pyramid varies the acoustic load, permitting
relatively simple high-cut adjustment and improving bandpass properties. 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.

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

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.
