SB13 Ultra – Unmatched Sound Quality and Extreme Performance – Elegant Footprint
The SB13-Ultra delivers an outstanding combination of high-tech components and features, handsome aesthetics, extreme performance, and easy room integration. The SB13-Ultra is the finest subwoofer in its class, with unparalleled performance value. Mission accomplished – SVS style.
13 Ultra Driver – Optimized For Sealed Applications
SVS optimized the famous Ultra 13 driver for a sealed application by revising the motor geometry and adding a unique voice coil along with a custom gap extension plate. The result is higher thermal power handling, a more symmetrical force/displacement profile, lower distortion, and increased linear stroke. Only SVS is willing to push the envelope this far to achieve the SB13-Ultra performance goals.
- FEA-optimized motor with copper shorting sleeve to reduce gap induction and distortion.
- Unique and optimized bifilar wound, 3″ diameter, ultra-high-power aluminum voice coil.
- Unique gap extension plate for additional linear stroke and reduced distortion.
- Dual linear-roll spiders and stitched parabolic surround for extreme excursion capability.
- Ultra-light and rigid Rohacell composite cone provides excellent transient response.
Sledge Amplification – 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 with LCD display, allowing for easy set-up and integration into any home theater or stereo system.
The amplifier equalization curve is specifically optimized for the SB13-Ultra, resulting in a gradual roll-off profile which provides superb transient response and extremely low group delay. This roll-off profile also takes the most advantage of available ‘room gain’, and under optimal conditions the SB13-Ultra can extend to 15 Hz or deeper in-room.
- 1000 watts RMS continuous power (3600 watts peak dynamic power).
- Efficient, cool-running Class D power with ‘green’ standby mode.
- Equalization curve optimized for enhanced transient response and to complement room gain.
- Stereo line-level RCA and balanced (XLR) I/O connections for the ultimate in connectivity.
- DSP control for the ultimate in refined behavior under all operating conditions.
- Extensive menu options and digital crossover allows easy integration into any 2-channel system.
- Intuitive and easy to use single knob controller with bright LCD display.
