An icon of SVS subwoofer innovation, the cylinder-shaped cabinet design of the PC12-Plus subwoofer lets you enjoy the performance benefits of a larger subwoofer, without requiring as much floorspace.
Commanding 12-Inch SVS High-Output Driver
Equally suited for music and home theater, the PC12-Plus powered subwoofer boasts a 12-inch down-firing Plus Series driver with dual high-grade ferrite magnets and an FEA-optimized motor for distortion-free performance at the most punishing drive levels. Dual linear-roll spiders and stitched parabolic surround allow the PC12-Plus to move massive amounts of air and achieve extreme excursion capability, while the ultra-light and rigid composite cone provides excellent transient response for the ability to start and stop on a dime.
Powerful and Sophisticated Sledge STA-800D Amplifier
Conservatively rated at 800 watts RMS and 2,300 watts peak power, the Sledge STA-800D DSP amplifier inside the PC12-Plus subwoofer delivers effortless power for maximum SPLs and sonic impact in movies and music, while maintaining pinpoint accuracy on frequency and transient response. It also has brains to match its brawn. A sophisticated DSP offers an array of filters and volume, gain, and phase controls for fine-tuning performance, and the efficient Class-D design consumes less than half-a-watt of power in stand-by mode.
Variable Port Tuning
Rated at 16-250 HZ +/- 3dB, the PC12-Plus subwoofer features variable port tuning so you can adjust output and extension based on listening preferences. For connections, the home theater subwoofer features a stereo line-level RCA and balanced XLR input/output connections along with an 80Hz high pass filtered output connections, continuously variable volume and phase controls, and a three top-firing 3-inch high-flow flared ports with large radius inner and outer flanges.
Nimble, yet powerful, the iconic SVS cylinder subwoofer delivers deeper extension and greater output per inch of floorspace than any traditional ported box subwoofer in existence. Musical bass is rendered with subtlety, nuance and toe-tapping aplomb while movie content invigorated with chest-thumping slam and impact as well as mood-setting low frequency effects.

"If there is a single subwoofer that revolutionized both the price/performance ratio and the way we buy subwoofers, the SVS Powered Cylinder is it." "...what it does do very well is the task of producing accurate and powerful bass with depth and finese that most other subs in this price range cannot match." "Outstanding bandwidth uniformity, linear response, low distortion and true 20Hz extension, etc... There is a whole lot to like about the PB12-NSD..." "...the PB12-NSD fires on all cylinders and provides a bulletproof, low distortion bottom end. $769 shipped to your door is a bargain price for this kind of all around performance."
AVForums' Russell Williams gives the SVS cylinders a Best Buy award!
"With this model, SVS literally thought outside the box." "The SVS PC12-Plus is an extremely versatile subwoofer that plays both music and film soundtracks in a way that belies its paltry asking price." "Highly recommended."
