SVS 4000 Series subwoofers demolish all preconceived notions about subwoofer performance and technology by unleashing reference caliber bass at a breakthrough value. With trickle down technology from the 16-Ultra Series, named top subwoofers in the world by nearly every audio publication and industry group, the 4000 Series obliterate expectations and deliver a level of unrivalled subwoofer performance only available from SVS. Earth-shaking SPLs, jaw-dropping deep bass extension, pinpoint control and accuracy with sophisticated control; all the hallmarks of a reference subwoofer are embodied in the SVS 4000 Series.

 

SB4000 Ultra – Bottomless Low Frequency Extension & Massive Output with Pinpoint Control & Accuracy.

A top choice for home theatre and audiophile music systems, the SB-4000 subwoofer delivers massive SPLs and extreme low frequency extension that will astonish even the most discerning listeners. A high-excursion 13.5-inch driver unleashes immense sonic energy while maintaining pinpoint control and accuracy from a 1,200 watts RMS, 4,000+ watts peak power amplifier featuring fully discrete MOSFET output and Analogue Devices most advanced audio DSP. Precise tuning for the SB-4000 is enabled from a subwoofer DSP smartphone app with custom presets. Chest-thumping slam and low frequency extension below the threshold of human hearing, with refined musicality – a level of subwoofer performance not seen at this price before. The SB-4000 subwoofer’s sophisticated DSP amplifier, innovative driver and a sealed box design master room gain and command a space with deeper bass and higher output levels than what is typically possible from a subwoofer of its size. An ideal option for reference quality bass in audiophile music or home theatre systems, the SB-4000 sets all performance benchmarks for a subwoofer and leaves larger and more expensive subs trembling in its wake.

 

High-Excursion SVS Driver – Legendary SVS Output and Control

The SB-4000 subwoofer delivers on the full potential of the Sledge STA-1200D amplifier’s power with precision and control to produce room energising 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 aluminium flat wire minimises distortion and power compression while providing excellent heat dissipation and linearity ensuring precise control.
  • Lightweight and rigid composite cone with premium glass fibre dustcap generate massive output with pinpoint accurate frequency response.
  • Proprietary injection moulded 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 SB-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, optimised frequency response curves, powerful DSP controls and more. 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.

 

Acoustically Inert and Rigidly Braced Sealed Box Cabinet Design

Inlaid front panel display, rounded edges and a curved metal grille on the sealed box SB-4000 cabinet give it a refined yet commanding look that blends visually with home theatres and high-end audio systems. It’s sealed cabinet design results in tighter, more musical bass and make it significantly more compact than ported box subwoofers with similar specs.

  • 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 artefacts within a room.

 

SB-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 SB-4000 powered 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
