SVS SB-1000 Pro Sealed Cabinet Subwoofer with 325W RMS Sledge STA-325D Amplifier and DSP Control App
The SVS SB-1000 Pro sealed cabinet subwoofer delivers deep low-frequency performance, extending down to 20Hz from a compact 13-inch enclosure. Built around an upgraded high-excursion 12-inch driver and an acoustically sealed cabinet, this subwoofer moves significant air volume while delivering clean, tight bass transients. Designed for space-conscious home theater setups and critical stereo listening systems, the SB-1000 Pro reproduces musical sub-bass details and low-end cinematic impacts with zero distortion.
At the core of the SB-1000 Pro is an integrated Sledge STA-325D Class-D amplifier delivering 325 Watts RMS (820+ Watts Peak Power) with discrete MOSFET output for continuous high-current drive. Sound tuning and room integration are controlled wirelessly via the SVS Smartphone DSP App for iOS and Android, allowing users to fine-tune volume, parametric EQ, low-pass filter, and custom room-gain presets directly from their listening position. Featuring a rigid MDF cabinet and an Intelligent Control Interface on the rear panel, the SVS SB-1000 Pro provides precise bass performance across any listening environment.
