SVS PB17-Ultra R|Evolution – 17-Inch Ported Powered Subwoofer in Gloss Black

Bass you don't just hear. Bass you experience.

The SVS PB17-Ultra R|Evolution is built for home theaters and high-performance audio systems where ordinary bass simply isn't enough. Its massive 17-inch driver, 2,800-watt RMS amplifier, and triple-ported enclosure combine to deliver extraordinary low-frequency output with extension down to an astonishing 12Hz.

This is SVS's flagship ported subwoofer, engineered to reproduce the deepest cinematic effects with physical impact while retaining the control and detail demanded by serious music listeners.

At its heart is a newly developed 17-inch driver with dual 8-inch voice coils, each powered by a dedicated monoblock amplifier section. A 295MHz Analog Devices DSP manages performance, while the SVS Subwoofer Control App and Auto EQ room correction help tailor the subwoofer to your listening environment.

Three selectable port configurations give you additional flexibility, allowing you to prioritize maximum output, deeper extension, or sealed-enclosure operation.

For a dedicated cinema or an uncompromising stereo system, the PB17-Ultra R|Evolution delivers the kind of low-frequency performance that transforms the entire listening experience.

A 17-Inch Driver Built to Move Serious Air

The PB17-Ultra R|Evolution features an entirely new 17-inch driver developed to reproduce demanding low frequencies with extraordinary output and control.

Its glass-fiber composite cone is supported by a substantial ferrite magnet motor assembly and a precision-engineered suspension system.

Dual 8-inch voice coils allow the driver to receive power from two independent amplifier sections. This architecture provides substantial current delivery while maintaining control over the cone's movement.

Whether reproducing the subtle decay of an acoustic bass note or the immense energy of a cinematic explosion, the driver is engineered to handle demanding passages without sacrificing detail.

2,800 Watts of Dual-Monoblock Power

The Sledge STA-2800D amplifier delivers a combined 2,800 watts RMS and more than 6,000 watts of peak power.

Unlike a conventional single-output subwoofer amplifier, the STA-2800D incorporates two independent Class D monoblock sections. Each drives one of the driver's dual voice coils.

Eight high-current MOSFETs provide the output capability needed for demanding bass reproduction.

An advanced switch-mode power supply with active power-factor correction and AC line conditioning helps maintain consistent power delivery.

The result is an amplifier designed to deliver enormous output while maintaining precise driver control.

Three Ways to Experience Deep Bass

One of the PB17-Ultra R|Evolution's most useful features is its adjustable port tuning.

Three large, high-flow ports work with the included foam port plugs to provide different operating configurations.

This flexibility allows you to experiment with different configurations based on your room, system, and listening preferences.

Intelligent Bass Management With SVS Auto EQ

Even a powerful subwoofer needs proper room integration.

The PB17-Ultra R|Evolution features a 295MHz Analog Devices DSP with 56-bit filtering to manage performance and provide advanced tuning capabilities.

The SVS Subwoofer Control App gives you access to volume, crossover, phase, polarity, room gain compensation, and parametric equalization directly from your smartphone.

SVS Auto EQ uses measurements from a smartphone microphone or compatible external microphone to analyze the room and calculate correction filters.

Three custom presets let you store different configurations for music, movies, and other listening preferences.

The rear-mounted OLED display also provides convenient access to essential settings without requiring your phone.

Built for Reference Home Theater

The PB17-Ultra R|Evolution is a substantial subwoofer, measuring nearly 30 inches deep and weighing more than 164 pounds.

Its heavily braced MDF cabinet is designed to minimize unwanted resonance, while screw-in iso-elastomer feet help reduce vibration transfer to the floor.

Balanced XLR and unbalanced RCA connections provide integration flexibility for premium AV processors, stereo preamplifiers, and other audio equipment.

For dedicated theaters with multiple seating positions, a dual-subwoofer configuration can also help achieve more consistent bass response throughout the room.
