SB17-Ultra R|Evolution
DEMO model in store

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, SB17-Ultra R|Evolution is the pinnacle of subwoofer performance. A massive 17-inch driver with first ever dual 8-in voice coils driven by the most powerful amplifier ever deployed in a consumer subwoofer with DSP intelligence far beyond anything available. All married to advanced power management and auto EQ room correction. 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.

Features

• High-Excursion 17-Ultra R|Evolution Driver  –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.
• 8-inch Dual Voice Coils – 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.
• Dual Mono Amplifier –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.
• Switch Mode Power Supply – Time aligns the AC voltage to the AC current while filtering and stabilizing incoming voltage to optimize signal quality and audio performance.
• 295 MHz Analog Devices DSP – 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.
• SVS Subwoofer Control Smartphone App – 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.
• Acoustically Tuned Sealed Cabinet Design – Sealed cabinet with double thick MDF and rigid internal bracing creates a resonance-free environment for pitch-perfect accuracy free from resonances and coloration.
