SVS PB17 Ultra R|Evolution 17-Inch Subwoofer in Piano Gloss Black - PB17-ULTRA-PIANO-GLOSS

SVS PB17-ULTRA-PIANO-GLOSS PB17 Ultra R|Evolution 17-Inch Subwoofer in Piano Gloss Black
The ultimate reference standard for low frequency design and performance from a ported cabinet subwoofer.
Born from three decades of SVS design expertise, the pinnacle of subwoofer performance is here with the PB17-Ultra R|Evolution. Reimagined dual mono-block STA-2800 amplifier technology, first ever 17-in driver with dual 8-in voice coils, and the most powerful DSP ever used in a consumer subwoofer married to advanced power management and auto EQ room calibration. 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.
Key Features
- 17-inch glass fiber composite cone with 55 lb toroidal ferrite magnet motor assembly render massive low frequency output down to 12Hz with pinpoint accuracy and control.
- Dual voice coil design ensures stable and consistent transfer of motor electro-magnetic energy to the 17-inch cone to maintain precise driver control with maximum efficiency.
- Each of the two Class-D mono-block amplifiers with MOSFET output stages drives one of the dual voice coils to double the amount of current being fed to the driver achieving effortless output with lower continuous current demand from a home’s AC circuit.
- Time aligns the AC voltage to the AC current while filtering and stabilizing incoming voltage to optimize signal quality and audio performance.
- The most advanced processor ever used in a consumer subwoofer optimizes every aspect of subwoofer output and usability to maintain flawless performance and intuitive control.
- Ported cabinet with high airflow 4-inch flared ports, double thick MDF, and rigid internal bracing creates a resonance-free environment for pitch-perfect accuracy free from resonances and coloration.
Features
- 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

- 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.- 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
- 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
- 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
While DSP remains absent from many subwoofers on the market, SVS integrated the most sophisticated DSP ever to optimize all aspects of performance and usability through unprecedented processing power.- 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
- 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 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.- 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 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.
- 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
- 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
