SVS SB-4000 Ultra 13.5" Sealed Cabinet Powered Subwoofer

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. Dual ferrite magnet motor assembly weighing nearly 40lbs generates immense magnetic force and excursion of the 13.5" driver to produce massive low frequency output well below the limits of human hearing. In addition to the front LCD display control panel, the 4000 Series subwoofer app is the most convenient way ever to control volume, access multiple DSP functions and program custom presets for one-touch tuning optimised for music, movies, gaming, and more. Adjust crossover frequencies, a three-band parametric EQ, polarity, room gain and more, all from your favourite seat.
