The SVS SB-3000 sits at the heart of SVS’s sealed subwoofer range, positioned between the compact SB-2000 Pro and the flagship SB-4000. It pairs a 13-inch high-excursion driver with the Sledge STA-800D2 amplifier platform, delivering 800 watts RMS with peaks exceeding 2,500 watts from a sealed enclosure measuring just 395 × 395 × 454 mm.
Driver and Motor Assembly
The SB-3000’s 13-inch driver is built around a dual ferrite magnet motor assembly. SVS designed this as a high-excursion unit, allowing the cone to travel further than conventional drivers of the same diameter. This extended excursion, combined with the sealed cabinet’s air-spring loading, enables the SB-3000 to reproduce frequencies down to 18 Hz (±3 dB) with controlled, accurate output rather than relying on port tuning for extension.
Sledge STA-800D2 Amplifier
The Sledge STA-800D2 is a fully discrete MOSFET Class D amplifier delivering 800 watts of continuous RMS power. SVS rates its peak output at over 2,500 watts. The amplifier integrates a 50 MHz Analog Devices DSP processor with 56-bit filtering, which SVS describes as the most advanced digital signal processor used in a subwoofer at this price point. The DSP handles parametric EQ, room gain compensation, and crossover duties internally, with variable phase control for precise alignment with main speakers.
Bluetooth App Control
All DSP functions are accessible via the SVS smartphone app for iOS and Android over Bluetooth. The app provides real-time control of volume, low-pass filter frequency, phase, and three bands of parametric EQ, each adjustable for frequency (20–200 Hz), boost (−12 to +6 dB), and Q factor. Custom presets can be saved and recalled for different listening scenarios. Physical controls on the rear panel mirror the app’s functionality for setup without a phone.
Connections
Rear-panel connectivity includes stereo RCA line-level inputs and outputs for daisy-chaining a second subwoofer, a dedicated LFE input for home cinema processors, a 12 V trigger input for automatic power-on with compatible AV receivers, and a USB port for firmware updates.
