SVS-4000-Series.jpgSVS has announced its newest subwoofer line, the 4000 Series. Incorporating technologies and features utilized in the flagship 16-Ultra Series, the 4000 Series includes three models: the SB-4000 sealed cabinet subwoofer, the PB-4000 ported cabinet subwoofer, and the PC-4000 ported cylinder cabinet subwoofer. All three subs use a 13.5-inch drive unit with a long-throw parabolic surround, driven by a Sledge STA-1200D amplifier that combines the high current output of discrete MOSFETs with Class D efficiency. More details on each sub are available in the press release below. The 4000 Series subs go on sale in December, with prices ranging from $1,499.99 to $1,999.99.

From SVS
SVS proudly announces the 4000 Series subwoofers, three new models loaded with advanced features and technology only available from SVS, at a price that redefines the cost of entry into reference quality bass for music and home theater fans. SVS 4000 Series subwoofers borrow heavily from the flagship SVS 16-Ultra Series, recipients of nearly every industry award in 2017, including the CES Innovations Best of Innovation for High Performance Audio and the European Imaging and Sound Association (EISA) "2017 Best Subwoofer."

Comprised of the SB-4000 sealed cabinet subwoofer, PB-4000 ported cabinet subwoofer and the PC-4000 ported cylinder cabinet subwoofer, each new SVS model features advancements to the driver, amplifier, cabinet and overall user experience that outpace anything available in the industry. The result is massive and effortless low frequency output below the threshold of human hearing, with accuracy in frequency response and pinpoint speed in transients, priced below lesser performing "reference" subwoofers.

Powering the 4000 Series is a commanding and sophisticated Sledge STA-1200D amplifier that combines the high current output of discrete MOSFETs with Class D efficiency. The unique design unleashes nearly limitless on-demand power while maintaining precise driver control, so the 4000 Series can be pushed beyond reference playback levels without flinching and still achieve accurate frequency response.

Harnessing the fathomless power of the Sledge amplifier is a 50-MHz Analog Devices Audio DSP with 56-bit filtering, the most sophisticated DSP engine ever used in a home audio subwoofer. The vast processing power enables pristine output and refinement that's true to the source material. The ideal amount of acoustic energy is produced at just the right moment with no overhang, at the exact playback level and frequency the artist, director or sound engineer intended. The DSP also unlocks subwoofer intelligence through precise tuning features, optimized frequency response curves, sophisticated user controls and more.

Drivers in the 4000 Series subwoofers are built for serious output and punishment. The proprietary SVS design features a dual ferrite magnet motor assembly weighing nearly 40 pounds and delivering immense magnetic force to a 13.5-inch drive unit with long-throw parabolic surround for extreme excursion, SPLs and longevity. A lightweight and rigid composite cone with glass fiber dustcap moves massive amounts of air to create tactile sonic energy without ever flexing or losing control. The result is pinpoint accurate frequency response and speed in transients, even at the most intense listening levels.

Launched originally with the flagship SVS 16-Ultra subwoofers, the 4000 Series also feature convenient control and custom presets via the SVS subwoofer DSP smartphone app for Apple and Android devices. The SVS app controls polarity, room gain, phase alignment, volume, parametric EQs and stores custom music, home theater and other presets for easy one-touch tuning. It's the simplest way to optimize bass response below the limits of human hearing from any seat in the house. No more back and forth from the subwoofer to the listening position to calibrate. For added convenience, bi-directional feedback shows updates in real time on both the app and subwoofer interface, and Bluetooth connectivity allows adjustments to be made when the subwoofer is not in sight. Control is also available via IR remote and a front panel display.

Active Power Factor Correction (PFC) within the 4000 Series 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 within each subwoofer creates a vanishingly low noise floor by eliminating the potential for ground loop hums from outside components resulting in absolute sonic transparency.

Subwoofers capable of such extreme performance levels require equally formidable cabinet designs, so the 4000 Series are built with double thick MDF and rigid internal bracing to support the drive unit and ensure an acoustically inert environment. The highly reinforced internal design eliminates any chance of coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference sound pressure levels.

"While the rest of the industry is chasing benchmarks SVS established with the 16-Ultra Series, we raised the bar and redefined what is possible at even lower price points, taking the finest technology available and applying it in a way that lets more people than ever enjoy the breathtaking benefits of reference quality bass," said Gary Yacoubian, SVS President and Managing Partner. "Audiophiles and home theater fans who understand high performance audio will recognize what a genuine accomplishment the 4000 Series is after the first bassline drops or action movie erupts to life. And for the price, there's simply nothing in the same area code."

The three SVS 4000 Series subwoofer models include:

SVS SB-4000 Subwoofer: Sealed Cabinet
Chest-thumping slam and extreme low frequency extension with pinpoint accuracy and refined musicality. The SB-4000'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. Sets all performance benchmarks and leaves larger and more expensive subwoofers trembling in its wake.
• Frequency Response: 19-310Hz +/-3 dB
• Max Low Frequency Output: 126.8 dB @ 32Hz 1/8 space 1m

SVS PB-4000 Subwoofer: Ported Cabinet
Staggering low-frequency output and subterranean deep bass extension down to 13Hz with an amazing degree of subtlety and finesse to thrill both action movie buffs and ardent audiophiles. Includes three port tuning modes, each with individual response curves to achieve the most accurate in-room frequency response possible. It's like having three subwoofers in one.
• Frequency Response: 16Hz to 200Hz +/-3 dB (standard mode), 13Hz to 200Hz +/-3 dB (extended mode), 18Hz to 200Hz +/-3 dB (sealed mode)
• Max Low Frequency Output: 134.5 dB @ 32Hz 1/8 space 1m

SVS PC-4000 Subwoofer: Ported Cylinder Cabinet
With a footprint measuring just 16" in diameter, the iconic cylinder subwoofer design is only available from SVS and achieves matchless low frequency output and deep bass extension per inch of floor space. The PC-4000 features three port tuning modes and comes standard with the SoundPath Subwoofer Isolation System for cleaner sounding bass with increased definition and more punch without room rattle and reduced bass bleed to the rest of the house.
• Frequency Response: 17Hz to 200Hz +/-3 dB (standard mode), 15Hz to 200Hz +/-3 dB (extended mode), 16Hz to 200Hz +/-3 dB (sealed mode)
• Max Low Frequency Output: 133.1dB @ 32Hz 1/8 space 1m

The 4000 Series starts shipping in early December 2017. The SB-4000 and PB-4000 are available in a premium black ash or piano gloss black finishes and come standard with a protective, non-resonant steel mesh grille. The PC-4000 features a piano gloss black top cap.

Pricing for the 4000 Series Subwoofers:
SB-4000: Premium Black Ash - $1,499.99, Piano Gloss Black - $1,599.99
