SB13-Ultra – Heroic Performance, Black-Tie Elegance
Are there 17 inches square in your home to make room for the most critically acclaimed subwoofer on the planet? The SB13 is the most popular Ultra for more than its modest stature alone. The flagship of our sealed models delivers super-hero levels of power, detail, speed and musicality. Yet, disguised in an elegant and compact cabinet it goes practically unnoticed in any décor—until it is called into action. You’ll quickly find the SB13’s reputation is well deserved and its value unparalleled. Mission accomplished – SVS style.

NewSledge Amplifier STA-1000D: Intelligent and sophisticated Power
The Sledge STA-1000D amplifier is a perfect match for the Ultra 13 driver, packing 1,000 watts of power and sophisticated DSP control. Comprehensive and extensive menu options are accessed via an intuitive single-knob interface and easy-to-use, LCD display. This will make your set-up and integration with home theater or stereo system quick and simple.
Sheer power alone is not enough. The SB13-Ultra’s amplifier equalization curve has been expertly optimized. Its roll-off is gradual, transient response superb and group delay extremely low. This roll-off profile makes the most of available ‘room gain’ so that under optimal conditions the SB13-Ultra can extend in room to 15 Hz or deeper. Even more, these characteristics make it ideal to pair with other SB13 Ultras for a multiple subwoofer configurations.
SVS 13.5” High Output Driver
To equip the SB13, SVS’s audio engineers started miles ahead of other subwoofers. Their advantage? The famed Ultra 13 driver. Which they then optimized for a sealed application. They revised the motor geometry, added a unique voice coil and custom gap extension plate. The result is a sealed subwoofer that delivers higher thermal power handling, more symmetrical force/displacement profile, lower distortion, and increased linear stroke. Only SVS engineers could start with the Ultra 13 driver. Only SVS engineers would push the envelope this far to deliver the clean, deep low end of the SB13-Ultra.
