The SVS PB-4000 Subwoofer delivers breathtaking dynamics and subterranean bass from a massive ported enclosure, ideal for serious home theater and music enthusiasts. It features a 13.5-inch high-excursion SVS driver with a 3-inch voice coil, driven by a powerful 1,200-watt RMS (4,200+ watts peak) Sledge Class D amplifier with Active Power Factor Correction. This combination yields immense, distortion-free output, reaching down to an astonishing 13 Hz (±3 dB) in Extended Mode.

Precision tuning is handled by a 50MHz Analog Devices DSP, controlled effortlessly via the SVS Subwoofer Control smartphone app (Bluetooth-enabled) or the front-panel display. The app offers comprehensive adjustments including low-pass filter, phase, polarity, and three parametric EQs for meticulous room optimization. Its triple 3.5-inch front-firing ports and robust MDF cabinet (with included port plugs for variable tuning) ensure exceptional performance. Weighing 153.2 lbs (23.4 inches H×20.5 inches W×30.0 inches D), the PB-4000 provides uncompromising, reference-level bass.

Jaw-Dropping Bass Extension and Output with Pinpoint Control and Accuracy
The SVS PB-4000 combines seismic power and fathomless low-frequency extension you can feel with refinement and musicality that suspends your sense of disbelief. With trickle-down technology from the 16-Ultra Series, named top subwoofers in the world by nearly every audio publication and industry group in 2017, the PB-4000 crushes expectations and delivers a level of unrivaled subwoofer performance only available from SVS.

high-excursion SVS Driver – Legendary SVS Output and Control
The PB-4000 subwoofer driver delivers on the full potential of the Sledge STA-1200D amplifier’s immense power with precision and control to produce room energizing SPLs and effortless low-frequency extension with pinpoint accuracy at all drive levels.

Sledge Amplifier – Massive Output, Sophisticated DSP, Advanced Power Management
Rated conservatively at 1,200 watts RMS, and 4,000+ watts peak power, the PB-4000 Sledge STA-1200D amplifier uses an efficient Class D design combined with fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other powered subwoofer manufacturer.

High Current Output of Fully Discrete MOSFETs with Efficiency of Class D Amplifier
The efficiency of a Class D amplifier with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense output and precise control for outstanding real-world subwoofer performance at all drive levels.

Sophisticated 50Mhz High Resolution Analog Devices Audio DSP
The most advanced digital processor ever used in a subwoofer maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning, optimized frequency response curves, powerful DSP controls, and more.

Variable Port Tuning Modes
Foam port plugs come standard with the PB-4000 and allow for variable tuning. Each response curve for the three port tuning modes; standard, extended, and sealed, is fully configured to the respective mode to achieve balanced and accurate low-frequency response with all tuning preferences.

Active Power Factor Correction (PFC) & Ground Loop Isolation
Serves as a line conditioner, surge suppressor and voltage regulator letting the amplifier deal with wide voltage fluctuations and ensuring the subwoofers operate flawlessly on any household circuit no matter how unstable the incoming current. An isolated circuit creates a vanishingly low noise floor by eliminating the potential for ground loop hums from outside components resulting in absolute sonic transparency.

PB-4000 Smartphone App – Easiest Way Ever to Manage Subwoofer DSP and Control
Groundbreaking smartphone app works with Apple iOS® and Android® devices to unleash the full depth, force, and nuance of the PB-4000 subwoofer by controlling all DSP functions including volume, parametric EQ, low pass filter, phase, polarity, room gain, port tuning, custom presets and system settings.
