SVS SB-4000 Active Subwoofer - Black Oak
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 theater systems, the SB-4000 sets all performance benchmarks for a subwoofer and leaves larger and more expensive subs trembling in its wake.
Unparalleled Low Frequency Depth, Power and Detail
The SVS SB-4000 powered subwoofer demolishes all preconceived notions about subwoofer performance and technology by taking command of any room with deep, effortless bass and adding visceral energy to every listening experience. 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 SB-4000 obliterates expectations and delivers a level of unrivaled subwoofer performance only available from SVS.
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.
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.
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.
Double thick 2-inch MDF front baffle and rigid internal bracing to support the massive drive unit and to ensure an acoustically inert environment.
