The SVS PB17-Ultra R|Evolution is the flagship ported subwoofer, engineered for unparalleled output, subterranean extension, and absolute bass fidelity. It features a massive 17-inch high-excursion driver with groundbreaking dual 8-inch voice coils, powered by a colossal 2,800-watt RMS (8,000+ watts peak) dual mono-block Class D amplifier. This allows it to plunge down to an astonishing 12 Hz (Extended Mode) with earth-shaking authority and pristine clarity.

Advanced control is at your fingertips via a 295MHz Analog Devices DSP, fully adjustable through the intuitive SVS Subwoofer Control smartphone app (Bluetooth-enabled) for volume, six-band parametric EQ, phase, multiple tuning modes (Standard, Extended, Sealed via included port plugs), and upcoming Auto EQ. Its triple 4-inch front-firing ports and robust MDF cabinet ensure resonance-free performance. Weighing 164.7 lbs (25.0 inches H×21.7 inches W×29.3 inches D), the PB17-Ultra R|Evolution is the ultimate choice for reference-level bass in any large home theater or music system.

Effortless Output from High-Excursion 17-inch SVS Driver
It was a ground-up process designing the largest, most formidable driver ever deployed in an SVS subwoofer. An all-new dual voice coil, suspension, basket, and extreme-excursion surround achieve chest-compressing sound pressure levels with flawless tonal accuracy.

- Lightweight and rigid 17-inch glass fiber composite cone with optimal stiffness-to-mass ratio for maximum efficiency and acoustic linearity
- 55lb four-piece toroidal ferrite electromagnetic motor generates massive force with precise control, remaining authoritative yet detailed and controlled
- Extreme-excursion catenary SBR rubber surround maintains pure, long-throw pistonic driver motion

Unerring Control from Revolutionary Dual 8-inch Voice Coils
Unprecedented dual 8-inch dual voice coils ensures stable transfer of electro-magnetic current to the 17-inch driver for authoritative output and pinpoint driver control.

- 4-layer bi-filar dual voice coil conducts the massive power from the dual-mono amplifier to the motor with maximum thermal efficiency, resulting in effortless acoustic output
- Copper clad aluminum voice coil wire combines the best properties of both elements, yielding ideal thermal capacity and magnetic field strength.

First Ever Dual Mono STA-2800D Amplifier Design with Discrete MOSFET Output
The sonic muscle behind the most powerful and highest fidelity SVS subwoofer amplifier ever developed. PB17-Ultra R|Evolution STA-2800D features technological breakthroughs never offered before in a consumer subwoofer to ensure refined behavior and pristine response at any volume.

Limitless headroom from dual mono-block Class-D amplifiers with MOSFET output stages
Each amp drives one of the dual voice coils within the motor to assert pinpoint control and maximize power fed to the driver
Eight 60 Amp 200 Volt MOSFETs deliver extreme high current for reference-level output with maximum efficiency

Performance Enhancing Switch Mode Power Supply
Regardless of the power coming out of your household circuit, the PB17-Ultra R|Evolution always maintains peak performance and remains impervious to voltage fluctuations.

- Onboard AC line conditioner filters and stabilizes incoming voltage, corrects waveform distortions, and eliminates electromagnetic and radio interferences to optimize signal quality and audio performance
- Ensures clean and consistent 160V rail voltage and optimal power delivery from a standard 15-amp home circuit
- Power-Factor-Correction (PFC) time aligns the AC voltage to the AC current resulting in less heat, greater efficiency, reliable peak power output, and the ability to maintain rated power over a wide-range of voltages
- FEA optimized convection cooling system has no exterior heatsinks, an extraordinary feat for such a powerful amplifier.

Extreme Subwoofer Intelligence – 295 MHz Analog Devices DSP
Orchestrating the cutting-edge amplifier, motor, and driver ecosystem is the most sophisticated DSP ever deployed in a consumer subwoofer.

- Accurately shapes in-room frequency response with absolute precision for faithful signal reproduction
- Monitors every function of the amplifier to stabilize AC voltage delivery to the power supply to maintain consistent peak output
- Multi-point thermal, voltage, and current monitoring system ensures maximum output and efficiency
- Advanced digital audio processing and DACs (Digital-to-Analog Converters) with 120 dB Signal-to-Noise Ratio provide greater headroom, lower noise, and pristine fidelity
