SVS’s original standard bearer for subwoofer performance, the PB13-Ultra is a legendary home theater subwoofer for its effortless power and subterranean low frequency extension down to 14Hz a with shocking musicality.
High Output SVS Ultra Series Driver Design
The flawlessly designed custom 13.5-inch driver is capable of handling the excursions and power needed to produce serious high output low bass. The woofer has an open but strong cast aluminum frame and a massive underhung magnet and motor assembly (tipping the scale at 55lbs) with a vented pole piece, large dual spiders and a large parabolic “high roll” surround making up the suspension. The surround is physically stitched to the cone, which is a significant design investment that reveals the performance-first approach to driver engineering.
Powerful and Sophisticated Sledge STA-1000D Amplifier
At the heart of the PB13-Ultra subwoofer is a muscular and sophisticated Sledge STA-1000D 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 and there’s always headroom to spare.
The DSP platform has an interface utilizing an LCD screen and a single knob / push button to control the settings. The PB13-Ultra's on-board DSP tools for fine-tuning the sound include dual digital parametric EQs 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 to keep track of all your settings, there’s a two-line LCD readout on the sub's back panel.
Variable Port Tuning
The PB13-Ultra Subwoofer employs a large bass-reflex (ported) cabinet design that allows its Ultra 13.5-inch driver to make long excursions for exceptionally deep bass at high output levels. Three flared, low-noise ports on the front of the enclosure minimize back-wall interaction for greater bass accuracy. Also included are three dense foam plugs that allow you to custom-tune how deep and loud the sub will play by blocking the ports. The PB13-Ultra's strong, rigid enclosure helps eliminate cabinet flex and resonance to keep your bass ultra-clean. Connections include a stereo line-level RCA plus balanced XLR inputs and outputs for flexible connectivity with a wide range of audio gear, including high-end stereo preamps and A/V preamp/processors.

Z-Reviews - Review of the PB13-Ultra Subwoofer
"...the PB13 will challenge you to find a single weakness... It reached the deepest notes with ease, and was very crisp and clear the whole time, without getting muddy or boomy. Did I mention it was smooth? It was oh so smooth."
Home Theater Shack reviews the PB-13 Ultra Subwoofer
"The PB13-Ultra was quite possibly the best subwoofer I've ever had in my system. It went lower and louder than any single-piece sub I've tried here, and it did so without producing a hint of excessive sound on the middle-bass octaves from 60Hz on up." "Massive wattage and slick control in a compact package." "The PB13-Ultra is a very powerful subwoofer that is competently engineered, heavily built, bulletproof, high tech and high output, possessing true extension to below 20Hz and a ton of configurability options. It’s a clear winner!"
