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
8-INCH DRIVER AND 150 WATT
High amplifier power assures enough power to deliver
shattering movie theater-like bass effects, and the down firing 8-inch cone
driver translates the power into clear bass sound. The YST-SW215 has a frequency
range of 30 to 200 Hz.
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.
The subwoofer is magnetically shielded so it can be placed
near a TV monitor or receiver without fear that it will degrade the
CONTINUOUSLY VARIABLE HIGH-CUT
The user adjustable continuously variable high-cut filter
sets the highest frequency the subwoofer will deliver. It can be set anywhere
from 50 to 150 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
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-SW215 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.
Two sets of inputs allow the versatile subwoofer to accept
either line level or speaker level input signals.
HEAVY-DUTY SPEAKER TERMINALS
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-SW215's cabinet is constructed of thick MDF to
increase rigidity and reduce vibration and resonance.
