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.
Introducing the SB13-Ultra
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.
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.
