Description

The SVS SB17-Ultra R|Evolution is SVS's flagship sealed subwoofer and winner of the EISA "Best Product – Subwoofer" award for 2025–2026. A brand-new 17-inch high-excursion driver with the first-ever dual 8-inch voice coils is driven by a dual-mono 2,800 W RMS amplifier, delivering reference-grade bass down to 15 Hz with the speed and control of a sealed design – equally at home in a high-end home theatre or a two-channel HiFi system.

  • 17-Ultra R|Evolution driver: 17" front-firing, high-excursion driver with glass-fibre composite cone, dual 8" voice coils, 54 lb ferrite motor assembly, dual shorting rings and 48.9 mm Xmax for massive, low-distortion output.
  • Dual-mono STA-2800D amplifier: 2,800 W RMS continuous (6,000 W+ peak) from two discrete Class D mono-block amps with eight 60 A MOSFET output devices – each amp drives one voice coil for pinpoint control.
  • Clean, stable power: switch-mode power supply with active power-factor correction and an onboard AC line conditioner keeps performance consistent regardless of mains fluctuations.
  • Advanced DSP: 295 MHz Analog Devices audio DSP with 56-bit filtering and a 120 dB SNR DAC.
  • Frequency response: 15 Hz – 320 Hz (±3 dB).
  • SVS app control (iOS / Android): volume, low-pass filter, phase, polarity, 6-band parametric EQ, room gain compensation, tuning modes and three custom presets; rear OLED display with flip function.
  • Connections: stereo RCA and balanced XLR inputs and outputs (daisy-chain multiple subs), 3–12 V trigger, IR input, and USB for firmware updates and powering the optional SVS SoundPath Wireless Adapter.
  • Cabinet: internally braced MDF in Piano Gloss Black with protective ABS grille and screw-in iso-elastomer feet.
  • Dimensions: 507 mm (H) × 495 mm (W) × 537 mm (D) with grille; 56.25 kg.
  • In the box: subwoofer, grille, iso-elastomer feet, heavy-duty power cord, quick start guide.
