Product Information

The PB12-NSD subwoofer is the ultimate subwoofer over-achiever. Simply put, it provides room-energizing, pants-flapping bass, for a fraction of the cost of the typical reference subwoofer. SPLs and output also compare with much larger ported box subwoofers but with a greater control and accuracy from the sophisticated Sledge amplifier, overbuilt driver, and precisely tuned cabinet.

True to SVS design philosophy, the PB12-NSD obliterates performance expectations for the price with a driver, amplifier, motor, and cabinet combination at an all-new low price. Equally adaptable for music, home theater, TV, and gaming, the PB12-NSD produces amazingly deep and articulate bass with pinpoint accuracy and speed in transients at all drive levels.

Sledge STA-400D Amplifier

Effortless power with smooth and precise signal processing for accuracy and clarity at all drive levels, the PB12-NSD’s STA-400D amplifier is conservatively rated at 400 watts RMS (800 watts peak power) and effortlessly delivers massive amounts of current to the motor and driver to create convincing cinematic and musical bass you can hear and feel at the most important moments. With digital bass management features and flexible setup options normally reserved for more expensive subwoofers, the Sledge amplifier makes it easy to optimize with any equipment in any room setup.

DSP for Fine-Tuning In-Room Performance

Internal Digital Signal Processing (DSP) allows for easy integration into rooms of all shapes and sizes as well as with all different models and brands of speakers.
