About The SVS SB17-Ultra R|Evolution Subwoofer
Born from three decades of SVS design expertise, the peak 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.
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" (432 mm) glass fibre composite cone with optimal stiffness-to-mass ratio for maximum efficiency and acoustic linearity
- 25 kg 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" (203 mm) voice coils ensure stable transfer of electro-magnetic current to the 17-inch driver for authoritative output and pinpoint driver control.
- 4-layer bi-filar dual voice coils conduct the massive power from the dual-mono amplifier to the motor with maximum thermal efficiency, resulting in effortless acoustic output
- Copper clad aluminium 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. SB17-Ultra R|Evolution STA-2800D features technological innovations never offered before in a consumer subwoofer amplifier with breakthroughs to ensure refined behaviour 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 8-inch 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.
- 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 systems 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
- 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 EQ Room Correction
Achieves pristine fidelity by resolving all the acoustic issues caused by your room in a few easy steps.
- Automatically tunes subwoofer output using your smartphone microphone or an external microphone and the SVS subwoofer app
- Applies equalization, capitalizes on available room gain, and optimises in-room frequency response at main listening positions for optimal in-room performance
- Will be available soon via an over-the-air SVS Subwoofer Control App update
