12" High Output Woofer: The front-firing 12" high output woofer of the
SVS SB-1000 powered subwoofer pumps out deep and powerful bass with low
distortion, for smooth and accurate performance on music and movies soundtracks.
The woofer features a lightweight 12" cone for enhanced sensitivity and
transient response, a long-throw suspension for high output at low
frequencies, plus a rubber surround for durability and long-life. It also
incorporates FEA-optimized motor technology for low distortion, high-power
voice coil for excellent thermal management, and vented pole piece for greater
STA-300D Sledge Amplifier: The SB-1000 powered subwoofer
employs a Sledge STA-300D amplifier with efficient and cool-running Class D topology. The
amplifier is conservatively rated at 300 watts RMS and 720 watts
Peak. This amp features a highly advanced DSP processor offering unmatched
control over the subwoofer at all volume levels, for distortion free bass.
Rigid Sealed Enclosure: The SVS SB-1000 powered subwoofer features a
rigid and strong cabinet to resist unwanted distortion caused by vibration. The
enclosure is an acoustic suspension (sealed) design for tight, accurate bass
response. The cabinet is elegantly finished in a premium black ash wood-grain
vinyl or gloss piano-black lacquer,
and fits with practically any décor.
Variable Controls: The SB-1000 subwoofer has simple and straightforward control
options that make integrating the subwoofer into your listening environment an
easy task. The control knobs are actually digital actuators for precise and
- Volume Control: The Volume Control (Min/Max) affects how loud the
subwoofer plays. It should be adjusted to match the output level of your
- Low Pass Crossover: This Low Pass Crossover affects the upper frequency limit of the
powered sub. The control
range is 50-160 Hz, along with a "LFE"
(disabled) setting. The slope of the low
pass crossover is 12 dB/octave. For connection to a home theater receiver, the low pass
should be set to "LFE" (disabled). For stereo receiver, it should be
adjusted to blend with the natural roll-off frequency of your loudspeakers.
- Phase Control: The Phase Control (0-180°)
delays the signal being processed through the amplifier. It should be
adjusted to obtain the most coherent and stable soundstage and transition
between your loudspeakers and the powered subwoofer.
Low-Level and High-Level Connectivity: Comprehensive and flexible connectivity
with low-level or high-level options allow for
easy set-up and integration into your home theater or stereo system
- LFE/RCA Inputs: These unbalanced RCA inputs are used for line-level
connections between your receiver and the powered sub. For a single mono
connection to a home theater receiver, use the R/LFE input. For stereo
receivers, use both the L/R inputs.
- Speaker Inputs: This connection method is for 2-channel stereo
applications where the integrated amplifier or stereo receiver only has
high-level (i.e., speaker-level) outputs. The powered sub's speaker inputs
consist of 5-way binding posts that will accept bare wire (up to 10AWG), pin-connectors,
spade-connectors, and banana plugs (dual or single).
- RCA Outputs: These unbalanced RCA outputs are used in stereo
applications to high pass the signal being sent to the loudspeaker
amplifier. The line level outputs feature a fixed 80 Hz 12 dB/octave high
Placement Options: If possible, place the subwoofer near the front
stage, for best blending with the front and center loudspeaker channels.
- Corner Placement: Corner placement will accommodate most rooms
and will reduce the chances for encountering a null (an acoustic
cancellation in the bass response) at the listening position. If your AV
receiver equalizes the subwoofer channel during auto-set-up, corner
placement will often provide the best overall performance.
- Other Placement Options: If corner placement sound excessively
boomy, then try moving the subwoofer to other available locations along the
front stage, listening for the best balance of output and a smooth accurate
response. Always redo the auto-set-up of your AV receiver after moving the
subwoofer to a different location to ensure the acoustic distance and
calibration level are set correctly.
- Dual Subs: To maximize the bass output and impact of your home
theater, two SB-1000s can be paired; one on either side of your room.
Auto/Standby & On Switch: If this switch is set to "Auto/Standby", it
will automatically turn-on the powered subwoofer in the presence of an audio
signal. If no signal is present for a period of several minutes, the powered
subwoofer will enter "Standby" mode, where power consumption will be less than
0.5 watts. If this switch is set to "On", the amplifier will remain on
continuously and will not enter "Standby" mode.
Power Status Light: The power status light is located on the
front-panel of the powered subwoofer in the upper left corner. The light will
illuminate blue when the amplifier is on. The light will illuminate red when the
amplifier is in standby mode.
3V-12V Trigger Input: When in standby mode, the powered sub's trigger
input (3.5mm) can be used to automatically turn on the powered subwoofer if a signal is sent to this input from another component in the system
(like your AV receiver) that features a trigger output.
