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 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 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. SB17-Ultra R|Evolution STA-2800D features technological innovations never offered before in a consumer subwoofer amplifier with 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 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

We try and keep on top of our pricing, but it's a mammoth task for one person. So, if you see this product offered cheaper elsewhere, or you are offered it for less elsewhere (proof will be required) and you feel like supporting an extremely independent retailer, do get in touch and we will do our very best to match or beat wherever we can. We can't promise to do so, as there may some extenuating circumstances where we just wouldn't be able to, but we'll always do what we can.

Needs to be like for like - new for new, ex-demo for ex-demo, same colour and specs etc.
