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.
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 unrivalled subwoofer performance only available from SVS.
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 dust-cap generates 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 Analogue 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.
