SVS PB-12-Plus powered subwoofer

With 800 watts of power, a 12" high-output woofer, and three flared, low-noise ports, the SVS PB12-Plus delivers powerful bass for your movies and music.

A subwoofer with plenty of brawn, and brains to match

At the heart of the PB12-Plus lies a muscular, high-efficiency Class D amplifier. The amp's built-in Digital Signal Processor (DSP) dynamically controls output power to ensure you hear nothing but deep, low-distortion bass no matter how loud your music and movies get.

The PB12-Plus's on-board tools for fine-tuning the sound include a digital parametric EQ with adjustable frequency, cut/boost, and Q values, plus a room gain compensation control with adjustable frequencies and slope to help tame pesky room response issues. And of course you get fully adjustable phase compensation and digital crossover controls. To make adjustments easier, and keep track of all your settings, SVS put a bright, two-line LCD readout on the sub's back panel.

A ported box with options

The PB12-Plus employs a large bass-reflex (ported) cabinet design that allows its SVS 12" high-performance Plus driver to make long excursions for exceptionally deep bass at high output levels.  SVS placed the sub's three flared, low-noise ports on the front of the enclosure to minimize back-wall interaction for greater bass accuracy. They also included three dense foam plugs that allow you to custom-tune how deep and loud the sub will play by blocking the ports. The PB12-Plus's strong, rigid enclosure helps eliminate cabinet flex and resonance to keep your bass ultra-clean.

Less Boom, but More Thundering Accurate Deep Bass

Rabbit from Cordova, TN on 2/12/2016

When i first got a SVS sound sub i didn't like it because i was use to boomy bass, the same boomy bass from everything. Once i got these (PB 12 plus and a PC 12 plus) I noticed the differences in movies bass, from gun shots to explosives going off to just deep notes in music scenes. These subs hit really hard and get really low. The bass is accurate and very clean. The setting/setup is alittle different beause of the DSP controls but just follow the instruction and if needed, just call SVS (a live person picks up ). I do suggest a receiver with an sub eq. My setup is Klipsch speakers(RF82,RC62,RS42) and Marantz sr6010 with these subs. Also i do suggest the piano black finish, it just looks awesome.

Pros: Deep Accurate Bass/ Loud and deep enough to make people around your house wonder if its thundering outside

Cons: None, well its not light weight

Features

12" High Output Woofer: The front-firing 12" high output woofer of the SVS PB12-Plus powered subwoofer pumps out deep and powerful bass with low distortion, for smooth and accurate performance on music and movies soundtracks. The woofer features an ultra-light and rigid 12" composite pulp/fiberglass cone for excellent transient response, dual linear-roll spiders and stitched parabolic surround for extreme excursion capability, and a bifilar wound 3" high-power aluminum voice coil for extreme power handling. The woofer's Finite Element Analysis (FEA)-optimized motor with copper shorting sleeve reduces gap induction and distortion, while its oversized pole vent allows for greater cooling.

STA-800D Sledge Amplifier: The PB12-Plus powered subwoofer employs a Sledge STA-800D amplifier with efficient and cool-running Class D topology. The amplifier is conservatively rated at 800 watts RMS and 2300 watts Peak. This amp features a highly advanced DSP & EQ processor offering unmatched control over the subwoofer at all volume levels, for distortion free bass.

Rigid Ported Enclosure: The SVS PB12-Plus powered subwoofer features a rigid MDF (Medium Density Fiberboard) cabinet with screw-in rubber feet and a non-resonant steel mesh grille to resist unwanted distortion caused by vibration. The cabinet utilizes a bass reflex (ported) design with three front-firing 3" high-flow ports with inner/outer port flares for smooth bass and extremely high output. The cabinet is elegantly finished in a premium black oak wood veneer or gloss piano-black lacquer, and fits with practically any décor.

Note: There are 3 foam port blockers included if the powered sub's bass sound is too "boomy" and you prefer a tighter bass response. You can choose to block one, two, three, or zero ports.

LCD & Controller: There is a rear-panel 3-way knob and a two-line LCD that allow you to set the various functions and parameters of the PB12-Plus powered subwoofer.

  • Volume: The Volume Control (-100 to 0dB) affects how loud the powered subwoofer plays. It should be adjusted to match the output level of your loudspeakers.
  • Low Pass Filter: The Low Pass Filter sets the frequency and slope for the low frequencies that will be played by the powered subwoofer. Frequency choices include 31, 40, 50, 63, 80, 100, and 125Hz.  Two Slope choices are available; 12 dB per octave and 24 dB per octave. You can disable the Low Pass Filter, if your AV receiver features an LFE output and built-in bass management for the subwoofer.
  • Phase Degree: The Phase Degree Function allows the adjustment of timing for the arrival of bass information from the subwoofer to the listening position. This allows for a finer degree of subwoofer integration with your main loudspeakers. The range of adjustment of this control is 0 to 10 milliseconds in 1 millisecond increments.

Room Correction: The SVS PB12-Plus powered subwoofer provides Room Compensation and P-EQ functions that help compensate for your room characteristics and boost the level of bass performance.

  • Room Compensation: The Room Gain Compensation Function allows the subwoofer to be set to compensate for the increase in low frequency sound based upon the size of the room, if it is felt there is too much bass. Small rooms will have a greater increase in low frequency sound than larger rooms. There is no need to use this control unless it is felt there is too much low frequency energy being generated in the listening environment. This function operates by setting a corner frequency of 40Hz (small size rooms), 31Hz (medium size rooms), 25Hz (large size rooms) or Disabled (no compensation), and allows a target slope of either 6 dB per octave (first order) or 12 dB per octave (second order) roll off from the selected corner frequency.
  • P-EQ Function: The P-EQ Function allows room environments that exaggerate certain bass frequencies to be reduced to by up to 12dB. Dips in frequency response can be boosted by up to 3dB. The result of a reduction tames "boominess" and "one note bass" phenomenon that occur when a narrow range of bass frequencies are significantly louder than surrounding frequencies. Boosting a dip can bring forward frequencies that are masked by normal levels around the dip. Available center frequencies include 31, 35, 40, 46, 50, 56, 63, 70, 80, 90, 100, 112, or 125Hz. Q values include 2.0, 2.4, 2.9, 3.6, 4.8, 5.7, 7.2, 9.6, or 14.4. The Level can then be adjusted from +3 to -12 dB in 1 dB increments.

Balanced & Unbalanced Connectivity: There are two types of input & output connectors on the PB12-Plus powered sub; Balanced XLR and unbalanced RCA. There are Left/Right input and output channels for both types of connectors.

  • Inputs: For a single mono input connection to a home theater receiver with an LFE output, use either the powered sub's left or right input. For stereo receivers without an LFE input, use both the L/R inputs. There is a switch below the input connectors labeled "Input Level". This switch can be used to select either consumer audio (Normal) or pro audio (Hi-Level) voltage levels depending on the source device.
  • Outputs: The output connectors are typically used to daisy-chain additional subwoofers. The powered sub's outputs are unfiltered.

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 PB12-Plus(s) 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.
