The ultimate reference standard for low frequency excellence from a sealed cabinet subwoofer design.
A quantum leap forward in design and performance with multiple groundbreaking innovations - the most formidable and sophisticated sealed 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, the pinnacle of subwoofer performance is here with the SB17-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, musicality, 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 15 Hz, far below the threshold of human hearing SB17-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 15Hz 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.
- Most convenient way to control all DSP functions, including: volume, 6-band parametric equalizer, low pass filter, phase, polarity, room gain, port tuning, system settings, custom presets, and auto room EQ.
- Sealed cabinet with 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
- 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 8-inch Dual Voice Coil
Unprecedented 8-inch dual voice coil ensures stable transfer of electro-magnetic current to the 17-inch cone 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 motorwith 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-2800 Amplifier Design with Discrete MOSFET Output
The sonic muscle behind the most powerful and highest fidelity SVS subwoofer amplifier ever developed. SB17-Ultra R|Evolution features breakthroughs 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 SB17-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..
- 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
