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.

  • Dual ferrite magnet motor assembly weighing nearly 40lbs generates immense magnetic force and excursion of the 13.5-inch driver to produce massive low frequency output well below the limits of human hearing.
  • Edge wound voice coil with eight-layer aluminum flat wire minimizes distortion and power compression while providing excellent heat dissipation and linearity ensuring precise control.
  • Lightweight and rigid composite cone with premium glass fiber dustcap generate massive output with pinpoint accurate frequency response.
  • Proprietary injection molded gasket and long-throw parabolic surround ensure longevity and allow extreme excursion and SPLs.

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

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

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

A single foam port plug come standard with the PB-4000 and allow for variable tuning. Additional port plugs are available upon request to support all tuning options*. 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.

*Since the vast majority of SVS subwoofer owners never use the port plugs and many end up in landfills, we've made them optional to be a bit more eco-conscious. We are happy to send port plugs free of charge if they will be used, just note in the special instructions during checkout.


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.

  • Connects via Bluetooth for convenient control even when subwoofer is out of sight.
  • 3-band parametric EQ controller allows precise adjustments for frequency slope and Q factor down to the single Hz level with four different slopes, so users can improve performance by eliminating peaks, nulls and other room issues.
  • Stores 3 custom presets for movies, music and other listening experiences such as sports or gaming.
  • 2-way feedback shows updates in real time on both the app and subwoofer interface

Acoustically Inert and Rigidly Braced Ported Box Cabinet Design

Inlaid front panel display, three front-firing, high-flow bass ports, rounded edges and a curved metal grille on the PB-4000 cabinet give it a refined yet commanding look that blends visually with home theaters and high-end audio systems.

  • Double thick 2-inch MDF front baffle and rigid internal bracing to support the massive drive unit and to ensure an acoustically inert environment.
  • Highly reinforced internal design and acoustic insulation eliminates all coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference volume.
  • Protective, non-resonant steel mesh grille and custom elastomer feet for reducing noise artifacts within a room.
  • 2-way feedback shows updates in real time on both the app and subwoofer interface

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
