SVS PB-4000 Ultra 13.5" Ported Box Powered Subwoofer

The SVS PB-4000 powered subwoofer combines seismic power and fathomless low frequency extension you can feel with refinement and musicality that suspends your sense of disbelief. 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 PB-4000 crushes 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. Thunderous low frequency output and extreme deep bass extension, with accuracy and control, the PB-4000 is a benchmark setting subwoofer on every level with unheard-of performance and features for even double the price. The sophisticated DSP amplifier creates three port tuning modes, each with individual response curves to achieve the most accurate in-room frequency response possible. With the PB-4000, it’s like having three subwoofers in one. Effortlessly powerful with bass that extends far below the threshold of human hearing, the PB-4000 creates a revelatory experience with every movie and music listening session. 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.
