Key Technological Breakthroughs

High-Excursion 17-inch SVS Driver

At the heart of this subwoofer lies a 17-inch glass-fibre composite cone with an extreme-excursion SBR surround. This driver moves air with authority and precision, extending down to 15Hz with unerring accuracy. The 55lb toroidal ferrite motor provides the muscle for chest-thumping impact without sacrificing detail.

Revolutionary Dual 8-inch Voice Coils

First in the industry, dual 8-inch voice coils feed the driver with stable, high-current power. The 4-layer bi-filar copper-clad aluminium windings ensure thermal efficiency and magnetic strength, resulting in effortless output and pinpoint control.

Dual Mono STA-2800D Class-D Amplifiers

SVS deploys the most potent amplifier ever seen in a consumer subwoofer: a dual mono-block Class-D design with eight 60A, 200V MOSFETs. This configuration yields limitless headroom and pristine response at any volume.

Switch Mode Power Supply and Power-Factor Correction

The onboard power management system stabilises voltage, filters out interference, and maintains a clean 160V rail. PFC and an FEA-optimised convection cooling system ensure reliable peak performance from a standard 15A home circuit.

295 MHz DSP and Smartphone Control

Orchestrating this engineering marvel is a 295MHz Analog Devices DSP, offering 56-bit filtering and 120dB SNR DACs. Fine-tune your sub with the SVS subwoofer app — soon to include Auto EQ room correction via OTA update — for a perfectly calibrated listening experience.

Performance in the Real World

Whether you’re watching cinematic blockbusters or diving into complex musical passages, the SB17-Ultra R|Evolution handles them all. Expect tight, punchy bass in action sequences and nuanced, room-shaking notes in orchestral and electronic music. The sealed design delivers fast transient response and seamless integration with your main speakers.
