SVS PB-4000 black lacquered

The SVS PB-4000 is a high-end subwoofer that pushes the limits of low-frequency reproduction. Designed to deliver an immersive sound experience for both music and home theater, this subwoofer combines power, precision, and versatility in an elegant design.

A powerhouse for breathtaking bass

At the heart of the PB-4000 is its impressive 34 cm driver, specially engineered to deliver deep, powerful bass. This transducer is driven by a Sledge STA-1200D Class D amplifier capable of delivering 1200 W RMS continuous power, with peaks up to 4000 watts. This combination allows the PB-4000 to reach down to 13 Hz, well below the threshold of human hearing, while maintaining remarkable control and accuracy.

The driver motor, equipped with a dual ferrite magnet, generates colossal magnetic force, enabling large excursions without distortion. The eight-layer flat aluminum wire voice coil ensures efficient heat dissipation and exceptional linearity, guaranteeing consistent performance even at high listening levels.

A high-tech brain for intelligent bass

The PB-4000 is not just powerful, it’s also smart. Its amplifier incorporates a 50 MHz Analog Devices DSP processor, the most advanced ever used in a subwoofer. This electronic brain allows precise control of the frequency response and offers advanced features to optimize the subwoofer’s performance in any environment.

One of the major innovations is the SVS control app for iOS and Android smartphones. This intuitive interface lets you fine-tune all subwoofer parameters, from the low-pass filter to phase, including room gain compensation. The user even has a three-band parametric equalizer to tailor the response to the room’s acoustics.

A versatile design to meet every need

The PB-4000 stands out for its flexible use. Its bass-reflex enclosure is equipped with three tuned ports, each of which can be sealed using the supplied foam plugs. This unique feature allows you to modify the sub’s response according to three modes: standard (all ports open), extended (one port closed), and sealed (all ports closed).

The standard mode offers the best balance between low-frequency extension and high output level, ideal for home theater. The extended mode prioritizes bass depth at the cost of a slight loss in efficiency, perfect for audiophiles seeking the lowest frequencies. Finally, the sealed mode focuses on precision and speed, particularly suitable for music listening.

Seamless integration into any system

Recognizing that the PB-4000 will be integrated into a wide range of setups, SVS has equipped its subwoofer with multiple connectivity options. Stereo XLR and RCA inputs and outputs allow easy integration into both consumer and professional systems. The extended input voltage range ensures optimal compatibility with a wide variety of equipment.

The front panel features an 8-character LED display, providing quick access to key settings. For those who prefer remote control, an infrared remote is included, in addition to the aforementioned smartphone app.

A tamed monster for refined listening

Despite its colossal power, the PB-4000 can also be subtle and nuanced. Its amplifier incorporates an intelligent limiter that prevents any distortion, even at extreme listening levels. Active power factor correction (PFC) ensures a stable and clean power supply, regardless of the quality of the electrical grid.

These advanced technologies enable the PB-4000 to reproduce low frequencies with surgical precision. Whether you want to feel the impact of an explosion in an action movie or appreciate the subtleties of a double bass in a jazz recording, this subwoofer delivers an immersive and faithful sound experience.
