The new 16-Ultra Series are the biggest and most powerful SVS subwoofers ever built and the culmination of all SVS engineering advancements, but that’s only part of the story.

SVS designed a completely new driver, amplifier and cabinet, scrutinized every design element and pioneered 3 game-changing subwoofer innovations to achieve unprecedented output levels, extreme low frequency extension, near-perfect frequency response accuracy, and pinpoint transient response.

One of these innovations would’ve made the 16-Ultra Series an engineering tour-de-force, but the combination of 3 subwoofer firsts and all new driver, amplifier and control platforms propel the SB16-Ultra and PB16-Ultra into the pantheon of all-time great audio products.


Massive All New 16” Ultra Driver with Unprecedented 8” Edge Wound Voice Coil.


Stunningly Powerful 1,500 Watts Continuous, 5,000+ Watts Peak Power Sledge Amplifier with Fully Discrete MOSFET Output.


Groundbreaking New Subwoofer Control and Bass Management Smartphone App for Apple® and Android® Devices.


Massive All New 16” Ultra Driver with Unprecedented 8” Edge Wound Voice Coil.

16” Driver with Record-Breaking 8” Edge Wound Voice Coil

To handle the crushing power of a 16” driver, SVS designed a massive 8” edge wound voice coil, the largest ever deployed in a consumer subwoofer. This innovation ensures ultra-low distortion and pinpoint control at the highest drive levels resulting in incredible output and low frequency extension, with accuracy in frequency response and speed in transients.

World-Class Driver Materials and Technology

Four of the heaviest toroidal ferrite magnets used in a consumer subwoofer generate unprecedented levels of magnetic force to drive the highest levels of excursion, SPL, and low frequency output. Cone material is a rigid but lightweight fiberglass resin composite that never flexes and conveys subtle and room-shaking low frequency effects with equal aplomb.


Stunningly Powerful 1,500 Watts Continuous, 5,000+ Watts Peak Power Sledge Amplifier with Fully Discrete MOSFET Output.

Fully Discrete MOSFET Output from Highly Efficient Class D Sledge Amplifier

Robust 64 Amp 200-Volt MOSFET’s provide the sonic muscle behind the astonishingly powerful 1,500 watts continuous, 5,000+ watts peak power amplifier with fully discrete output. MOSFET output offers far superior power handling and tighter control when compared to the integrated circuit output stage found in nearly all other Class D subwoofer amplifiers.

Sophisticated Analog Devices Audio DSP with Active Power Correction

Effortless power must be harnessed to ensure refined behavior and pristine output at the most demanding drive levels. The 16-Ultra Series subwoofers use the audio industry’s most advanced Analog Devices Audio DSP to handle the nearly limitless power so the perfect amount of low frequency energy is released at just the right time and just the right frequency. To ensure a steady flow of power, the amplifier uses an active Power Factor Correction (PFC) regulator to smooth input current to a clean and steady 360V DC, while using 30-50% less current than a subwoofer without PFC.


Groundbreaking New Subwoofer Control and Bass Management Smartphone App for Apple® and Android® Devices.

Subwoofer Control and DSP Is Easier and More Convenient than Ever

The 16-Ultra subwoofer app is the most powerful bass management and subwoofer control app ever developed and the easiest way ever to adjust volume, crossover frequencies, parametric EQ, polarity, room gain and all other DSP functions. It also features convenient custom presets for one-touch tuning in any room or system, from your favorite seat.

Bi-directional feedback shows adjustments in real time on both the app and subwoofer interface and Bluetooth connectivity allows control, even when the subwoofer is out of sight.
