A quantum leap forward in design and performance with multiple groundbreaking innovations - the most formidable and sophisticated ported subwoofer ever developed.

All-new 17-inch driver with first-ever dual 8-inch voice coils. The most powerful amplifier ever deployed in a consumer subwoofer with unprecedented dual mono-block design married to the extreme intelligence of a 295MHz DSP. All managed by the most sophisticated subwoofer control app, now with auto EQ room correction (available soon via over-the-air update).

Born from three decades of SVS design expertise, PB17-Ultra R|Evolution is the pinnacle or ported subwoofer performance. A massive 17-inch driver with first ever dual 8-in voice coils driven by the most powerful amplifier ever deployed in a consumer subwoofer with DSP intelligence far beyond anything available. All married to advanced power management and auto EQ room correction. The benchmark for reference subwoofer experiences has arrived.

Breathtaking low frequencies with unerring accuracy, room-shaking output, and stop-on-a-dime control. The deep, chest-thumping slam of cinematic soundtracks and the delicate nuance of musical bass always rendered truthfully.

Whether heard or felt, low frequencies are handled effortlessly without sacrificing sonic fidelity and refinement. With extension to 12 Hz, far below the threshold of human hearing, PB17-Ultra R|Evolution brings sound to life with convincing, visceral, and jaw-dropping impact.

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

SVS Subwoofer Smartphone Control App Now with Auto EQ Room Correction

Compatible with Apple iOS, Google Android, and Amazon Fire platforms, the SVS Subwoofer Control Smartphone app allows convenient subwoofer tuning and management.

Controls for volume, low pass filter, phase, polarity, six parametric equalizers, room gain compensation, tuning modes, power management settings, and more
Includes three convenient memory presets for fast and easy system adjustments to match your listening preferences – music, movies, night mode, and more
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
Amplifier Rear Panel OLED and control interface provide fast and direct control of the most important features and includes a convenient “Display Flip” function

SVS Subwoofer Auto Room Correction

Achieves pristine fidelity by resolving all the acoustic issues caused by your room in a few quick and easy steps.

Automatically tunes subwoofer output using your smartphone microphone and the SVS subwoofer app
Applies equalization filters, capitalizes on available room gain, and optimizes in-room frequency response at main listening positions for optimal in-room performance.
Simple process requires just a few steps for significant improvements to in-room response
Will be available soon via an over-the-air SVS Subwoofer Control App update
