SB13-Ultra - Piano - Outlet - 1373

Chest-thumping power, fathomless low frequency extension, pinpoint accuracy and refined musicality - all from a relatively compact 17-inch square cabinet. With a legendary 13.5-inch Ultra driver and 1,000 watts RMS, 3,600 watts peak Sledge STA-1000D DSP amplifier, the SB13-Ultra is an all-time great subwoofer for music and home theater fans alike.

Quick Specs

  • Driver | 13.5"
  • Amplifier | 1000 watts RMS (3600 watts peak)
  • Freq. Response | 20-460Hz ±3 dB
  • Port Size & # | N/A
  • Dimension | 17.4" (H) 17.4" (W) 18.5" (D)
  • Weight | 92lbs

A perfect 17-inch square, the SB13-Ultra subwoofer’s compact design is ideally suited for spaces where larger subwoofers wouldn’t fit, but deep, palpable bass is still desired. Painstakingly engineered, the SB13-Ultra is loaded with advanced design elements that set it apart from the competition.

High Output SVS Ultra Series Driver Design

Instead of merely adapting the previous Ultra driver to a more compact sealed enclosure, SVS engineers radically revised the motor geometry, added a unique, ultra-high-power aluminum voice coil, and developed a custom gap extension plate that increases linear stroke and reduces distortion. Add to that dual linear-roll spiders, a stitched parabolic surround, and the ultra-light but rigid Rohacell composite cone material of the 13-Ultra driver, and the result is an incredibly robust subwoofer with extreme excursion that easily outperforms subwoofers costing twice as much.

Powerful and Sophisticated Sledge STA-1000D Amplifier

To complement these driver refinements, the SB13-Ultra employs an integrated 1,000 watts RMS, 3,200+ watts peak power DSP Sledge amplifier with sophisticated DSPs perfectly matched to the driver and cabinet, and an equalization curve optimized for enhanced transient response and to complement room gain. Although it’s rated to deliver 20Hz to 460Hz (±3dB), in the right room, with the right settings, it can easily reach down to a gut-wrenching 15Hz, without diminishing the nuanced textures and incredible transient response that audiophiles demand of music. Its room gain compensation control also allows the SB13-Ultra to sonically adapt for optimal in-room frequency response. Power users will appreciate the two-band parametric equalizer (PEQ), yet this advanced feature is easily disabled for users who prefer to rely on the bass management of their favorite preamp or receiver.

Acoustically Inert, Rigidly Braced Cabinet

The SB13-Ultra subwoofer cabinet is rigidly braced and acoustically inert for uncompromising performance and its understated but elegant design allow it to blend with any room’s décor, while still delivering thunderous low frequency impact that’s impossible to ignore.Described in reviews as authoritative, stunning, immensely powerful, pitch-perfect, versatile, and jaw-droppingly accurate, words and accolades only tell part of the story. The feeling you get when a musical bassline drops or your home theater erupts to life during an action movie sequence, or the shivers that goes down your spine when it resolves a deep but delicate sonic detail; these are the moments when the SB13-Ultra subwoofer shows its ultimate value.

"I found the bass to be authoritative, while at the same time complimentary to the mids and highs.
