Incredible low frequency output and extreme deep bass extension, with accuracy and control, the PB-4000 is a benchmark subwoofer at every level with unmatched performance and features over comparable subwoofers with at least double the price.
The advanced DSP amplifier creates three port tuning modes, each with individual response curves to achieve the most accurate frequency response in the room. With the PB-4000, it's like having three subwoofers in one. Effortlessly powerful with bass that reaches far below the threshold of human hearing, the PB-4000 creates a revelatory experience with every listen at movies and music.
The SVS PB-4000 powered subwoofer destroys all preconceptions of subwoofer performance and technology by dominating any room with deep, effortless bass and adding visceral energy to any listening experience. With trickle-down technology from the 16-Ultra Series, which was named the best subwoofers in the world in 2017 by nearly every audio publication and industry group, the SB-4000 overturns expectations and delivers an unparalleled level of subwoofer performance only available from SVS.
The PB-4000 subwoofer delivers the full power potential of the Sledge STA-1200D amplifier with precision and control to produce room-enhancing SPLs and effortless low-frequency extension with pinpoint accuracy at all station levels.
Conservatively rated at 1,200 watts RMS and over 4,000 watts peak power, the PB-4000 STA-1200D Sledge STA-1200D amplifier uses an efficient Class D design combined with a fully discrete MOSFET output and an advanced Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other powered subwoofer manufacturer.
High power efficiency of fully discrete MOSFETs with the efficiency of a Class D amplifier
Efficiency of a Class D amplifier with the ability to move huge amounts of current through the fully discrete MOSFETs, allowing immense output and precise control for outstanding real-world subwoofer performance at all station levels.
Advanced 50Mhz high-resolution analog audio DSPs
The most advanced digital processor ever used in a subwoofer maintains its accuracy and impeccable sound quality thanks to advanced in-room tuning, optimized frequency response, powerful DSP controls and more.
Variable port tuning modes.
Foam ports come standard with the PB-4000 and allow for variable tuning. Each response curve for the three tuning modes; standard, extended and sealed, is fully configured to the appropriate mode to achieve a balanced and accurate low frequency response with all tuning preferences.
Active Power Factor Correction (PFC) & Ground Loop Isolation.
Serves as a line conditioner, surge suppressor and voltage regulator allowing the amplifier to handle large voltage fluctuations and the subwoofers to function perfectly on any domestic circuit, no matter how unstable the incoming current. An isolated circuit creates a vanishingly low noise floor by eliminating the chance of ground loop hum from external components, resulting in absolute sound transparency.
The groundbreaking smartphone app works with Apple iOS® and Android® devices to unleash the full depth, power and nuance of the PB-4000 powered subwoofer by controlling all DSP functions including: volume, parametric EQ, low pass filter, phase, polarity, room gain, port tuning, custom presets and system settings.
