View at SVS

Unique cylinder cabinet design saves floorspace while delivering chest-pounding, pinpoint accurate output comparable with ported box designs. Comes standard with SVS SoundPath Subwoofer Isolation System.


Reference Caliber Bass with Less Floorspace Required

The SVS PC-4000 powered subwoofer astounds with its ability to command a room with massive low frequency output and deep bass extension that can be heard and felt while maintaining accuracy and control, all from a striking cylinder cabinet that measures only 16” in diameter. There is no subwoofer in the world that comes close to what the PC-4000 can do without taking up 2 or 3 times as much floorspace. 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 PC-4000 shatters expectations and delivers a level of unrivaled subwoofer performance only available from SVS.


High-Excursion SVS Driver – Legendary SVS Output and Control

The PC-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

The PC-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.


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.


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.


Three foam port plugs come standard with the PC-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.


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.


PC-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 PC-4000 poweredsubwoofer 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


SoundPath Subwoofer Isolation System for Cleaner, Tighter Bass with Less Room Rattle

Elastomer feet on the PC-4000 improve bass performance while reducing floor and wall vibrations, noise artifacts and complaints from neighbors or roommates. De-coupling a subwoofer from the floor results in inherently tighter and cleaner sounding bass. It’s also the next best thing to sound-proofing and ideal for carpeted rooms, hardwood floors or any space where room rattles, buzzes or vibrations are present.


Acoustically Inert and Rigidly Braced Ported Cylinder Cabinet Design

An inlaid front panel display, the first of its kind for an SVS cylinder subwoofer, and a stylish and durable fabric cabinet covering give the PC-4000 a refined yet commanding look that blends visually with home theaters and high-end audio systems. The unique cabinet design goes vertical to increase cabinet volume to achieve incredible low frequency output on par with much larger ported box subwoofers, but with much less floorspace required.


  • Double thick 2-inch MDF cabinet walls 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.

Deliciously Crispy

The PC-4000 delivers room‑shaking, precise low end with deep extension and punch—its 13.5" driver and Sledge STA‑1200D amp give remarkably controlled, high‑SPL performance. Reviewers from TONEAudio MAGAZINE and Audiophilepure highlight its taut slam and easy tuning via the app-based DSP, all in a compact cylinder footprint for music and movies.

TONEAudio MAGAZINE

"But seriously, having the level of bass extension and slam that the PC-4000 adds, makes you wonder how you ever did without it!"

Pros

  • Very deep, authoritative low-frequency extension (around 15–16Hz in extended/ported modes) that creates visceral, room-pressurizing impact.
  • Tight, fast dynamics and high headroom—output is controlled and impactful without lingering overhang, ideal for kinetic film soundtracks and punchy music.
  • Flexible, precise integration thanks to the SVS app, Bluetooth DSP control, parametric EQ and pluggable port tuning for easy room‑matching.

&

Cons

  • Limited finish choices—reviewers note the model is only offered in piano-gloss black, which may not suit all rooms.
  • While extremely capable, it isn’t the absolute deepest 4000-series model (the PB-4000 reaches lower, ~13Hz), so subsonic extension is slightly less extreme.
