SB–4000 SubwooferChest–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 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 DetailThe 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.Sledge Amplifier – Massive Output, Sophisticated DSP, Advanced Power ManagementRated 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 AmplifierEfficiency 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 DSPMost 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.Active Power Factor Correction (PFC) – Ground Loop IsolationServes 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.

I have an SVS SB4000 Piano Gloss Powered Subwoofer. My customer had to let it go when they moved. The unit works flawlessly, and was used in a non smoking home. Never over-driven. There are some scuff marks from the move. See pictures. In a dim room, you really dont see the scuffs but they are there in the right light. This sub is about 4 years old. It comes with a power cord and remote (remote in new condition). This sub is crazy heavy coming in at just over 100 lbs. It is shipping in the original box and packaging, minus the top piece of foam for the top of the sub which I had to improvise on. Driver | 13.5Amplifier | 1200 watts RMS (4000+ watts peak)Freq.
