SVS PB-1000 Pro Ported Cabinet Subwoofer with 325W RMS Sledge STA-325D Amplifier and DSP Control App
The SVS PB-1000 Pro redefines performance expectations for ported subwoofers in its class, delivering output down to 17Hz with exceptional musical detail and accuracy. Featuring a redesigned 12-inch high-excursion driver paired with a dual-ported cabinet, this subwoofer moves immense volumes of air to reproduce low-frequency extension without chest-pounding distortion. Built for both home theater immersion and audiophile music setups, the PB-1000 Pro provides room-shaking low-end dynamics while maintaining precise cone control.
At the heart of the PB-1000 Pro is the Sledge STA-325D Class-D amplifier, generating 325 Watts RMS (1,000+ Watts Peak) of MOSFET power to easily handle demanding sonic passages. Integration and tuning are effortless thanks to the SVS Smartphone App for iOS and Android, which offers wireless control over volume, parametric EQ, low-pass filter, phase, and custom room-gain presets directly from your seat. Featuring dual dual-port cabinet ports and a Intelligent Control Interface on the rear panel, the SVS PB-1000 Pro offers flexible setup options for any room environment.
