SVS PB17-Ultra R Evolution 17" Subwoofer

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
