With the PB-4000, it’s like having three Sub Woofers in one. Effortlessly powerful with bass that extends far below the threshold of human hearing, the PB-4000 creates a revelatory experience with every movie and music listening session.
The SVS PB-4000 combines seismic power and fathomless low frequency extension you can feel with refinement and musicality that suspends your sense of disbelief. With trickle down technology from the 16-Ultra Series, named top Sub Woofers in the world by nearly every audio publication and industry group in 2017, the PB-4000 crushes expectations and delivers a level of unrivaled Sub Woofer performance only available from SVS.
The PB-4000 Sub Woofer driver delivers on the full potential of the Sledge STA-1200D amplifier’s immense power with precision and control to produce room energising SPLs and effortless low frequency extension with pinpoint accuracy at all drive levels.
Rated conservatively at 1,200 watts RMS and 4,000+ watts peak power, the PB-4000 Sledge STA-1200D amplifier uses an efficient Class D design combined with fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other powered Sub Woofer manufacturer.
Efficiency of a Class D amplifier with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense output and precise control for outstanding real-world Sub Woofer performance at all drive levels.
Most advanced digital processor ever used in a Sub Woofer maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning, optimized frequency response curves, powerful DSP controls and more.
Foam port plugs come standard with the PB-4000 and allow for variable tuning. Each response curve for the three port tuning modes; standard, extended and sealed, is fully configured to the respective mode to achieve balanced and accurate low frequency response with all tuning preferences.
Serves as a line conditioner, surge suppressor and voltage regulator letting the amplifier deal with wide voltage fluctuations and ensuring the Sub Woofers operate flawlessly on any household circuit no matter how unstable the incoming current. An isolated circuit creates a vanishingly low noise floor by eliminating the potential for ground loop hums from outside components resulting in absolute sonic transparency.
Groundbreaking smartphone app works with Apple iOS and Android devices to unleash the full depth, force and nuance of the PB-4000 Sub Woofer by controlling all DSP functions including: volume, parametric EQ, low pass filter, phase, polarity, room gain, port tuning, custom presets and system settings.
Inlaid front panel display, three front-firing, high-flow bass ports, rounded edges and a curved metal grille on the PB-4000 cabinet give it a refined yet commanding look that blends visually with home cinema and high-end audio systems.
