SB13 Ultra subwoofer
Effortless output, shocking bass extension and pitch perfect musicality from one of the most positively reviewed and critically acclaimed subwoofers in history. The SVS SB13-Ultra offers a perfect mix of massive output and low frequency extension with musicality and accuracy, all from a stylish cabinet measuring only 17-inches all around.
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.
