The SB16-Ultra's massive 16" woofer weighs 56 lbs!
The SB16-Ultra is SVS's flagship sealed-box subwoofer. Whether your entertainment tastes run to Hollywood mayhem or traditional jazz, this sub's way with low frequencies combines audiophile-pleasing accuracy and musicality with mind-boggling power.
This heroic design uses a high-output 16" driver and a smart 1500-watt amplifier, for effortless handling of even the most demanding bass passages in your favorite music and movies.
The SB16-Ultra features the biggest driver ever used in an SVS subwoofer. This lightweight yet rigid 16" cone is connected to an 8" edge-wound voice coil - the largest we've ever heard of in a consumer subwoofer. Large cones are by nature difficult to control, but that oversized voice coil ensures accurate frequency response and quick transients, for bass that never sounds "slow" or boomy.
It takes serious electronic muscle to power and control such a massive woofer cone, and the built-in Sledge STA-1500D amplifier is more than up to the task. Unlike many Class D amps, this one's discrete MOSFET outputs can deliver incredible amounts of current, helping it push that 16" woofer to extreme levels of performance. Keeping all this power under control is an advanced Analog Devices digital signal processor.
The third big innovation puts precise control over the SB16-Ultra at your fingertips. SVS's smartphone app gives you total control from your Apple® or Android® device. It handles all DSP functions and conveniently stores custom presets. For added convenience, 2-way feedback shows updates in real time on both the app and subwoofer display, and built-in Bluetooth® allows adjustments to be made even when the subwoofer is not in sight. You can also control the sub via the intuitive front-panel display, or with the supplied remote.
The SB16-Ultra's on-board tools for fine-tuning the sound include three digital parametric EQs with adjustable frequency, cut/boost, and Q values. Room Gain Compensation control gives you a way to help tame pesky room response issues, like the tendency of bass to become overpowering in smaller rooms. And of course you get fully adjustable phase compensation and digital crossover controls.
To make adjustments easier, SVS moved the LED display to the sub's front panel. And they also included stereo line-level RCA plus balanced XLR inputs and outputs for flexible connectivity with a wide range of audio gear, including high-end stereo preamps and A/V preamp/processors.
SVS SB16-Ultra owner's manual
16" High Output Woofer: The SVS PB16-Ultra power subwoofer employs a light and rigid 16" Ultra driver cone which consists of a premium fiberglass resin composite with optimal stiffness to mass ratio to maximize movement of air and sonic energy without ever distorting or losing control. Pushing the driver are four massive, dedicated toroidal ferrite magnets that unleash a staggering 95mm peak to peak Xmech excursion (82mm Xmax) and the highest levels of motor force and palpable SPLs. An 8" edge wound voice coil ensures ultra-low distortion and pinpoint control at the highest drive levels resulting in incredible output and low frequency extension. By nature, larger drivers are more difficult to control, but the unprecedented voice coil design ensures accuracy in frequency response and speed in transients without ever sounding boomy.
STA-1500D Sledge Amplifier: A conservatively rated 1,500 watts continuous / 5,000 watts peak power Sledge STA-1500D amplifier pushes the 16" driver to extreme levels of performance. This discrete MOSFET amplifier delivers astonishing levels of effortless, distortion-free power. This enormous amount of power is harnessed and controlled by an advanced 50MHz Analog Devices Audio DSP with 56-bit filtering to handle the nearly limitless power, only unleashing the perfect amount of low frequency energy at just the right time.
Acoustically Inert MDF Enclosure: The SVS PB16-Ultra powered subwoofer features a rigid MDF (Medium Density Fiberboard) cabinet with a double thick MDF front baffle and rigid internal bracing to support the massive drive unit and to ensure an acoustically inert environment. The highly reinforced internal design eliminates any chance of coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference sound pressure levels. Screw-in rubber feet and a non-resonant steel mesh grille further resist unwanted distortion or coloration caused by vibration.
Control Types: The SVS PB16-Ultra Subwoofer can be controlled from the new SVS Mobile App, an included IR Remote Control, or via the front-panel for unprecedented flexibility when optimizing performance for room layout, speakers, system set-up and more.
Control Functions: The following control functions are available.
Balanced & Unbalanced Connectivity: There are two types of input & output connectors on the PB16-Ultra powered sub; Balanced XLR and unbalanced RCA. There are Left/Right input and output channels for both types of connectors.
Auto/Standby & On Switch: If this switch is set to "Auto/Standby", it will automatically turn-on the powered subwoofer in the presence of an audio signal. If no signal is present for a period of several minutes, the powered subwoofer will enter "Standby" mode, where power consumption will be less than 0.5 watts. If this switch is set to "On", the amplifier will remain on continuously and will not enter "Standby" mode.
Trigger Input: The powered sub's 3.5mm Trigger Input (3V-12V) will automatically turn the subwoofer on/off when a signal is sent to it from another component in the system (typically the pre/pro or AV receiver). The other component in the system must be equipped with a trigger output feature and requires a TS 1/8" mono-minijack cable (sold separately)
Placement Options: If possible, place the subwoofer near the front stage, for best blending with the front and center loudspeaker channels.
