SVS Subwoofer SB17-Ultra R|Evolution Sealed Subwoofer

Or would you prefer the deeper bass of the ported enclosure PB17-Ultra?

  • Bass Extension down to 15 Hz

17” Driver (woofer) 

  • Dual 8” Copper Clad Aluminum (CCA) Voice Coils 
  • High-Excursion (long throw) 
  • Extreme Excursion Catenary SBR Rubber Surround 
  • Glass Fiber Cone is both lightweight and rigid with optimal stiffness-to-mass ratio
  • 55lb Toroidal Ferrite Electromagnetic Motor 

Two STA-2800l Class-D Monoral Amplifiers (one for each voice coil)

  • Dual Mono Design lowers the continuous current demand on residential AC 
  • Eight 60 Amp 200 Volt MOSFETs

Switch Mode Power Supply 

  • Impervious to voltage fluctuations with a clean and consistent 160V rail voltage and optimal power delivery from a standard 15-amp 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
  • Internal AC line conditioner filters and stabilizes incoming voltage, corrects waveform distortions, and eliminates electromagnetic and radio interferences.
  • FEA optimized convection cooling system has no exterior heatsinks

295 MHz Analog Devices DSP 

  • Monitors every function of the amplifier to stabilize AC voltage delivery to the power supply for continuous peak performance
  • Multi-point thermal, voltage, and current monitoring systems 
  • Advanced digital audio processing and DACs (Digital-to-Analog Converters) with 120dB Signal-to-Noise Ratio 

SVS Subwoofer Control Smartphone App

  • Controls DSP functions including Volume, 6-Band Parametric Equalizer, Low Pass Filter, Phase, Polarity, Room Gain, Port Tuning, System Settings and Custom Presets.

SVS Subwoofer Auto Room Correction

  • Automatically tunes subwoofer output for optimized in-room performance using the builtin microphone on your smartphone. 

Acoustically Tuned Cabinet Design

  • Double thick MDF and rigid internal bracing
