SB-4000 Subwoofer

The SVS SB-4000 Subwoofer delivers reference-grade bass from a compact sealed cabinet, combining breathtaking power with pinpoint accuracy. It features a proprietary 13.5-inch high-excursion SVS driver, powered by a colossal 1,200-watt RMS (4,000+ watts peak) Sledge Class D amplifier with discrete MOSFETs and Active Power Factor Correction. This ensures immense output with pristine clarity, reaching down to 19 Hz (±3 dB). Advanced control comes via a 50MHz Analog Devices DSP, fully adjustable through the intuitive SVS Subwoofer Control smartphone app (Bluetooth-enabled) for volume, parametric EQ, phase, and custom presets. A front-panel LED display offers direct control. The robust, acoustically inert MDF cabinet guarantees uncolored bass. With XLR and RCA connectivity and a weight of 102.3 lbs, the SB-4000 (18.3 inches H×17.8 inches W×20.9 inches D) excels in both music and home theater, providing tight, musical, and room-shaking bass.
