Commanding 12-Inch SVS High-Output Driver
Equally suited for music and home theater, the PB12-Plus powered subwoofer boasts a 12-inch front-firing Plus Series driver with dual high-grade ferrite magnets and an FEA-optimized motor for distortion-free performance at the most punishing drive levels. Dual linear-roll spiders and stitched parabolic surround allow the PB12-Plus to generate incredible output through extreme excursion capabilities while maintaining control over the ultra-light and rigid composite cone, so it can stop on a dime with no overhang.
Powerful and Sophisticated Sledge STA-800D Amplifier
Conservatively rated at 800 watts RMS and 2,300 watts peak power, the Sledge STA-800D DSP amplifier inside the PB12-Plus subwoofer delivers effortless power for maximum SPLs and sonic impact in movies and music, while maintaining pinpoint accuracy of frequency and transient response. It also has brains to match its brawn. A sophisticated DSP offers an array of filters and volume, gain, and phase controls for fine-tuning performance, and the efficient Class-D design consumes less than half-a-watt of power in stand-by mode.
Variable Port Tuning
Rated at 16-250 HZ +/- 3dB, the PB12-Plus subwoofer features variable port tuning so you can adjust output and extension based on listening preferences. For connections, the home theater subwoofer features a stereo line-level RCA and balanced XLR input/output connections along with an 80Hz high pass filtered output connections, continuously variable volume and phase controls, and three top-firing 3-inch high-flow flared ports with large radius inner and outer flanges.
Deft, yet powerful, the SVS PB12-Plus subwoofer delivers deeper low frequency extension and greater output than any ported box subwoofer in its class. Musical bass is rendered with subtlety, nuance and toe-tapping aplomb while movie content is brought to life with seat-rumbling slam and impact as well as mood-enhancing low frequency effects.

"Probably the best deal going on a high end subwoofer." "From its ungodly output capabilities, true 20Hz extension, and ability to play clean and distortion free, the PB12-Plus DSP has truly earned the right to be called a "subwoofer."
