SVS SB-1000 Powered subwoofer 12"Inch- (Black Ash)

Product Research


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 cooling.
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 noise-free adjustment.
Volume Control:
  • The Volume Control (Min/Max) affects how loud the subwoofer plays.
  • It should be adjusted to match the output level of your loudspeakers.
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 pass filter.

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.
