An icon of SVS subwoofer innovation, the cylinder-shaped cabinet design of the PC13-Ultra subwoofer lets you enjoy the performance benefits of a larger subwoofer, without sacrificing the floorspace required of a reference ported subwoofer.
Stunningly Potent 13.5-Inch Down Firing SVS Ultra Driver
Equally matched for music and home theater, the PC13-Ultra powered subwoofer boasts a 13.5-inch down-firing Ultra 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 PC13-Ultra to move massive amounts of air and achieve extreme excursion capabilities while maintaining control over the ultra-light and rigid fiberglass composite cone, so it can start and stop on a dime with no overhang, even with the most challenging music tracks.
Powerful and Sophisticated Sledge STA-1000D Amplifier
Conservatively rated at 1,000 watts RMS and 3,200 watts peak power, the Sledge STA-1000D DSP amplifier inside the PC13-Ultra subwoofer delivers effortless power for maximum SPLs and sonic impact in movies and music, while maintaining pinpoint accuracy in 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 in-room performance. Plus, the efficient Class-D amplifier design consumes less than half-a-watt of power in stand-by mode.
Variable Port Tuning
Rated at 15-200 HZ +/- 3dB, the PC13-Ultra 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 three top-firing 3.5-inch high-flow flared ports with large radius inner and outer flanges.
Effortless power and extreme low frequency extension without sacrificing detail or musicality, the SVS PC13-Ultra cylinder subwoofer delivers greater output per inch of floorspace than any traditional ported box subwoofer in existence. Musical bass is rendered with delicate refinement and toe-tapping aplomb while movie soundtracks are unleashed with chest-thumping slam and impact as well as mood-setting low frequency effects, all from a subwoofer that blends seamlessly with any speakers.

"The SVS PC13-Ultra seemed to easily handle whatever I threw its way. Bass had excellent low end extension, with no bottoming out…At an MSRP of $1,699 it is a real bargain for the performance you are getting!"
The PC13-Ultra Subwoofer Receives Stereowiseplus.com's Editor's Choice Award
"The SVS SB13-Ultra is an exceptional product that is true to SVS's tradition of offering higher performance for the money through R&D and design... this is an exceptionally high-performance subwoofer that can accurately reproduce the sound of music or movies." "Despite turning up the PC13-Ultra way higher than ARC suggested, I never ran out of headroom while watching movies. Not once did the SVS complain, distort, or otherwise signal that it was anywhere near reaching its limits."

Sound + Vision Reviews the PC-13 Ultra Subwoofer
"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!
"So as to not mince words, the PC13-Ultra knocked me on my tail. We're talking wall shaking, glass-rattling, floor-rumbling bass." "The PC13-Ultra is a fantastic subwoofer. It has tons of power, useable output well into the infrasonic range, yet remains musical. How SVSound manages to make such an amazing product for $1,399 is beyond me. It must be that disintermediation thingy. I already own five subwoofers, but I still didn't want to let this one go. Highly recommended!"
