Engineering Masterpiece. Unmatched Bass Innovation.
The SB16-Ultra isn’t just a subwoofer—it’s a seismic leap in bass performance and engineering. Featuring three groundbreaking innovations that redefine what a subwoofer can be, it has rightfully earned its place among the most elite audio products ever created.
Unprecedented 16" SVS Driver with 8" Edge-Wound Voice Coil
At the heart of the SB16-Ultra is a colossal 16-inch Ultra driver—the largest and most advanced ever from SVS—powered by an industry-first 8-inch edge-wound voice coil. This groundbreaking design ensures ultra-low distortion, lightning-fast transient response, and flawless accuracy, even at extreme volume levels. Supported by four massive toroidal ferrite magnets and capable of a staggering 78mm peak-to-peak excursion, this driver unleashes room-shaking bass with absolute control and precision.
Sledge STA-1500D Amplifier – 1,500 Watts RMS, 5,000+ Watts Peak
Harnessing immense power with finesse, the Sledge STA-1500D amplifier delivers a conservative 1,500 watts continuous and over 5,000 watts peak. Featuring fully discrete 64A, 200V MOSFETs, it offers superior dynamic control and ultra-clean output, far surpassing standard Class D amplifiers. Coupled with a 50MHz Analog Devices DSP and 56-bit filtering, this amplifier ensures that every note of bass is delivered with exacting precision and perfect timing.
Advanced App Control via Smartphone (iOS & Android)
The SB16-Ultra features an innovative Bluetooth-enabled app that gives you full control over DSP settings, volume, custom presets, and advanced tuning—all from your smartphone. Real-time two-way feedback and intuitive controls make it easier than ever to fine-tune low frequencies with precision from anywhere in the room.
Acoustically Inert, Rigidly Braced Cabinet
To contain and control its immense power, the SB16-Ultra is housed in a robust, acoustically optimized cabinet built with a double-thick MDF front baffle and extensive internal bracing. This design completely eliminates cabinet coloration and resonance, even at reference playback levels, preserving the purity and integrity of your audio.
The SB16-Ultra is not just a subwoofer—it’s a revelation in low-frequency performance.
Built for those who demand uncompromising accuracy, massive output, and intelligent control.
