Description

Experience Revolutionary Performance and Technology from the Most Advanced Ported Subwoofer in SVS' History: 164.7-Pound PB17-Ultra R|Evolution Re-Imagines What's Possible 

The very name of the SVS PB17-Ultra R|Evolution subwoofer provides a strong hint about the levels of performance, technology, intelligence, and flexibility you’ll experience from the most sophisticated ported-cabinet design in the company’s fabled history. Equipped with a proprietary 17-in high-excursion driver with dual eight-inch voice coils, dual-mono STA-2800 amplifier, and 295MHz Analog Devices DSP with double-precision 56-bit filtering PB17-Ultra R|Evolution delivers stunning low-frequency detail and harmonics with reference-grade accuracy, output, and control. Heard and felt, the low end registered by PB17-Ultra R|Evolution remains both refined and controlled, and extends down to 12Hz — a level far below the threshold of human hearing.

At once providing body-shaking cinematic slam from blockbuster movies and live sporting events, as well as delicate musical nuances and revealing textures from musical programs, PB17-Ultra R|Evolution epitomizes stability, impact, realism, efficiency, and speed. It uses a massive 55-pound toroidal ferrite magnet motor assembly in its glass-fiber composite cone driver and two Class D monoblock amplifiers with MOSFET output stages, Each drives one of the dual voice coils to double the amount of current fed to the driver, achieving effortless output with lower continuous current demand from your AC circuit. Its DSP arrives as the most advanced processor ever found in a consumer-grade subwoofer, while the switch-mode power supply further optimizes the signal quality and overall sonics.

In addition to breathtaking engineering that extends to eight 60A 200V MOSFETs, onboard AC line-conditioner filters, and a FEA-optimized convection cooling system free of exterior heatsinks — read more about all of the crazy-good specifics on PB17-Ultra R|Evolution below — this 164.7-pound beast makes life easy with a smartphone control app and amplifier interface compatible with Apple iOS, Google Android, and Amazon Fire platforms. Enjoy convenient subwoofer calibration and management with controls for practically every function, memory presets, variable port tuning modes, and a rear-panel OLED that offers fast, direct access to the most important features — and which comes complete with a “Display Flip” option.

And forget about any concerns about whether PB17-Ultra R|Evolution will interface with your room and system. This mind-bending subwoofer has auto-room correction that tunes the output using your smartphone microphone and the SVS subwoofer app. Here, you can apply equalization filters, capitalize on available room gain, and optimize in-room frequency response at main listening positions for optimal performance.

Measuring 25 x 21.7 x 29.3 inches (HWD), PB17-Ultra R|Evolution is housed in a robust MDF cabinet with strategic internal bracing to cancel resonance even at the highest volumes. Nickel-plated spring terminals, a protective ABS grille frame with fabric mesh cover, triple four-inch ports, screw-in iso-elastomer feet, and a supplied six-foot power cord round out a subwoofer that currently has no equal on the market.

Effortless Output from a High-Excursion 17-Inch Driver
The largest, most formidable driver ever deployed in an SVS subwoofer features an all-new dual voice coil, suspension, basket, and extreme-excursion surround that achieve chest-compressing sound pressure levels with flawless tonal accuracy. The lightweight and rigid 17-inch glass fiber composite cone has an optimal stiffness-to-mass ratio for maximum efficiency and acoustic linearity. A 55-pound four-piece toroidal ferrite electromagnetic motor generates massive force with precise control, remaining authoritative yet detailed and controlled, while an extreme-excursion catenary SBR rubber surround maintains pure, long-throw pistonic driver motion.

Unerring Control from an Eight-Inch Dual Voice Coil
SVS’ eight-inch dual voice coil ensures stable transfer of electro-magnetic current to the 17-inch cone for authoritative output and pinpoint driver control. A four-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. A copper-clad aluminum voice coil wire combines the best properties of both elements, yielding ideal thermal capacity and magnetic field strength.

First Dual-Mono STA-2800 Amplifier Design with Discrete MOSFET Output
The sonic muscle behind the most powerful and highest-fidelity SVS subwoofer amplifier ever developed features breakthroughs to ensure refined behavior and pristine response at any volume. You get 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 60A 200V 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, PB17-Ultra R|Evolution always maintains peak performance and remains impervious to voltage fluctuations. The power supply 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. An onboard AC line conditioner filters and stabilizes incoming voltage, corrects waveform distortions, and eliminates electromagnetic and radio interferences. Finally, an FEA-optimized convection cooling system has no exterior heatsinks.

Extreme Intelligence Via a 295MHz Analog Devices DSP
While DSP remains absent from many subwoofers on the market, SVS integrated the most sophisticated DSP to optimize all aspects of performance and usability through unprecedented processing power. It monitors every function of the amplifier to stabilize AC voltage delivery to the power supply for continuous peak performance. Multi-point thermal, voltage, and current monitoring systems maintain maximum performance and greatest efficiency. And advanced digital audio processing and DACs with 120dB signal-to-noise ratio provide greater headroom, lower noise, and pristine fidelity.

Subwoofer Smartphone Control App and Amplifier Interface
Compatible with Apple iOS, Google Android, and Amazon Fire platforms, the SVS Subwoofer Control smartphone app allows convenient subwoofer calibration and management. It includes controls for volume, low pass filter, phase, polarity, six parametric equalizers, room gain compensation, tuning modes, power management settings, and more. Plus, three convenient memory presets for fast and easy system adjustments to match your listening preferences – music, movies, night mode etc. Variable port tuning modes with included port plugs enable customized frequency response curves for Standard, Extended, and Sealed to allow tuning for maximum output or deep bass extension and transient speed. An amplifier Rear Panel OLED and control interface provide fast and direct control of the most important features and includes a convenient “Display Flip” function.
