16-Inch Ultra Driver, Discrete MOSFET Amplifier, Smartphone Control, and Largest Voice Coil in a Consumer Subwoofer: Reference Unit Exemplifies Scale, Extension, Power

A recipient of top honors from Home Cinema Choice, Sound & Vision, Stereophile, and CES, SVS' SB16-Ultra has been deemed nothing short of "the best subwoofer ever made" by HomeTheaterReview. Stocked with a fully discrete MOSFET amplifier capable of 5,000W peak RMS, eight-inch edge wound voice coil, prodigious precision-machined driver motor, FEA-optimized cast-aluminum basket, and fiberglass resin-composite 16-inch Ultra cone driver, the 122-pound SB16-Ultra exemplifies control, extension, effortlessness, tautness, strength, and oodles of power. Top it all off by controlling everything from your smartphone via SVS' intuitive app, which handles all DSP functions and stores custom presets. It couldn't be easier to fine-tune bass surpassing 16Hz at reference volumes from wherever you wish to sit.

"It's almost in a whole different category of low-frequency sound. May well be the best subwoofer ever made."
– HomeTheaterReview

"[It] was clear that a single SB16-Ultra could produce more than enough bass extension and slam in my large listening room."
– Larry Greenhill, Stereophile, Class A Recommended Component

Groundbreaking technology, rigorous design, and extreme testing in real-world and laboratory environments allow SB16-Ultra to achieve massive output levels, extreme low-frequency extension, near-perfect frequency response accuracy, and pinpoint transient response. One huge advancement that allows SB16-Ultra to handle the crushing force of a 16-inch driver is its eight-inch edge-wound voice coil, the largest ever deployed in a consumer subwoofer. It ensures ultra-low distortion, efficient heat dissipation, exceptional linearity, and nearly zero power compression. By nature, larger drivers are more difficult to control, but the cutting-edge voice coil design ensures accuracy in frequency response and speed in transients without becoming boomy.

"Competes with top-performing subs costing twice or more [its] price."
– Sound & Vision, Top Pick of the Year

Four dedicated toroidal ferrite magnets push the light, rigid, 16-inch driver and unleash a staggering 78mm peak to peak excursion and the highest levels of motor force and palpable SPLs. The driver cone consists of a premium fiberglass resin composite with optimal stiffness to mass ratio to maximize movement of air and sonic energy without distorting or losing control. Conservatively rated at 1,500 watts continuous, 5,000+ watts peak power, the SB16-Ultra Sledge STA-1500D amplifier's 64-Amp, 200-Volt MOSFETs serve as the sonic muscle. Discrete MOSFET output results in superior handling and tighter control of the amplifier power and represents a major upgrade over the integrated circuits found in most Class D subwoofers. SB16-Ultra also uses the industry's most advanced 50MHz Analog Devices Audio DSP with 56-bit filtering to handle the nearly limitless power, unleashing the ideal amount of low-frequency energy at just the right time.

Take our word for it – our that of the audio and home-theater press. You need to experience this subwoofer, backed by our 100% Money-Back Guarantee and SVS' five-year unconditional manufacturer's warranty.

"Fear-inducing SPLs. Bass that you feel as well as hear. Delicious weight and scale, without a trace of distortion. ...It's jaw-on-the-floor stuff."
– Home Cinema Choice

"...It will embarrass the audio systems in many commercial movie theaters."
– PCWorld

See Updates in Real Time, Adjust Settings When You Want with Bluetooth
For added convenience, two-way feedback shows updates in real time on both the app and subwoofer interface. Bluetooth connectivity allows adjustments to be made even when the subwoofer is not in sight. Control is also available via IR remote and an intuitive front panel display.

Smart, Nearly Indestructible Construction
SB16-Ultra is built with a double-thick MDF front baffle and rigid internal bracing to support the drive unit and ensure an acoustically inert environment. The highly reinforced internal design eliminates any coloration or resonance from the cabinet, even when deep low frequencies are played at reference sound-pressure levels.
