"Smile-inducing bass, the kinetic energy reached deafening reference listening levels…My jaw was stuck ajar…Highly Recommended."
"Reproduced rippling, subterranean bass notes that go from audible to sensory… The best subwoofer I’ve heard.”
“SVS has taken clean, deep bass to another level. The 16-Ultras push the envelope in every respect.”
"The power and depth of the bass this sub produces makes AV experiences more visceral. There was never an instance where the demands of what I listened to exceeded what the PB16-Utra could deliver. The best-performing, highest-impact sub I’ve heard."
"Tight and natural sounding. The SVS SB16-Ultra was capable of subtlety but also brought grandeur when asked. Hit hard when it needed to and had a soft touch in those moments when less-is-more. It never strained at any volume, no matter how loud I cranked it. At times beautiful and other times thunderous. A top-notch subwoofer."
"Spending 2.5-3 times more money won’t guarantee better performance. A single SB16-Utra sounds better than any single $4000 subwoofer. I can’t over-state how good the SB16-Ultra sounds, makes me want to use every possible over-the-top adjective, and on top of the sound quality, it plays so loudly and so cleanly. Very strong bass that drives performance to you-are-there levels with more dynamic impact leading to a more visceral and exciting (adrenaline?) listening experience."

"Hearing, or feeling, subsonic notes is a treat and I thank SVS for engineering and producing a subwoofer that is capable of doing this while maintaining quality sound with low distortion. Bravo! A monster of a sub. Incredible depth and detail and perfect for intense, bone crushing bass. Competes with subwoofers costing much more."
"Within minutes of testing it for the first time, we loved it unconditionally. Watching a movie through a 5.1 system, or listening to music, is revelatory and is some of the best fun we’ve had with a piece of audio equipment. The PB16-Ultra is the single best home subwoofer available today."
"No matter the material I threw at it, the sub delivered bass that was massive yet tight and lightning fast. Had no problem energizing the air in my large family room, producing tactile bass that hammered my chest, and delivering next-level bass realism, letting you feel the soundtrack and experience the action more deeply. The SB16-Ultra is a force multiplier, improving the performance of any system you add it to. I give it my highest recommendation."
“I've heard almost all of the top subwoofers currently on the market. The SB16-Ultra sounds like none of them. It's almost in a whole different category of low-frequency sound.”
"This is the scariest subwoofer I’ve ever played with. I am not able to go to the limit on this subwoofer. It makes the fur on my arms stand up."

"Instead of bass that booms, it's bass that hits, and it hits hard. Deep and authoritative, the SB16-Ultra can flex its ample muscle and deliver impressively clean output and very high sound pressure levels and it has features and aesthetics that are unmatched. Betters the competition in every way."
"Extraordinary. Hit the air like a hammer. The sounds grabbed us with two hands and dragged us into the middle of the action. The most outstanding subwoofer for combining power and high precision ever."
"SVS has outdone themselves. This is a 'move the bar' type of product. It does everything exceptionally well, never revealing a single weakness. The 16-Ultra subwoofers expertly blends precision and power into one cohesive package, remaining composed at all times. Makes everything sound good."
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, extremelow 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.
PB16-Ultra features a massive 16” Ultra driver with astonishing 8" edge wound voice coil, a stunningly powerful 1,500 watts continuous, 5,000+ watts peak power Sledge amplifier with fully discrete MOSFET output, triple 3.5" front-firing high-flow ports and an innovative subwoofer control and DSP smartphone app with custom presets for precise tuning. The ultimate ported box subwoofer.
An unrelenting passion for breathtaking bass performance and engineering perfection guided every aspect of the PB16-Ultra subwoofer’s development. Groundbreaking technology, rigorous design and extreme testing in real world and laboratory environments allowed SVS to achieve unmatched low frequency extension and output capabilities all while keeping it amazingly detailed and articulate. The culmination of all SVS design advancements, PB16-Ultra represents an incomparable bass experience. Nothing else comes close.
One of these groundbreaking innovations would’ve been enough to make the PB16-Ultra an engineering tour-de-force, but the combination of 3 subwoofer firsts propels the SVS PB16-Ultra into the pantheon of all-time great audio products.
When designing the biggest and most formidable driver ever used in an SVS subwoofer, it was of utmost importance to meet or exceed the same supreme standards of control and accuracy as every other subwoofer SVS manufactures. One huge advancement that allows the PB16-Ultra to handle the crushing force of a 16-inch driver is the 8-inch 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. 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.
Pushing the driver are four massive, dedicated toroidal ferrite magnets that unleash a staggering 95mm peak to peak excursion and the highest levels of motor force and palpable SPLs. The light and rigid 16-inch Ultra driver cone 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.
Conservatively rated at 1,500 watts continuous, 5,000+ watts peak power, the PB16-Ultra Sledge STA-1500D amplifier’s 64 Amp 200-Volt MOSFETs are the sonic muscle behind arguably the most powerful and highest fidelity subwoofer amplifier ever developed. Discrete MOSFET output unbridles the nearly limitless power in the Sledge amplifier and pushes the 16-inch driver to extreme levels of performance. They also represent an upgrade over the less robust integrated circuit output stages found in nearly all other Class D subwoofer amplifiers.
Effortless power must be harnessed to ensure refined behavior and pristine output at the most demanding drive levels. To achieve this, the PB16-Ultra subwoofer uses the audio industry’s most advanced 50 MHz Analog Devices Audio DSP with 56bit filtering to handle the nearly limitless power, only unleashing the perfect amount of low frequency energy at just the right time.
Compatible with Apple® and Android® platforms, the innovative PB16-Ultra smartphone app unleashes the full depth, force and nuance of the world’s finest subwoofer. The groundbreaking SVS subwoofer app controls all DSP functions and conveniently stores custom presets. It’s the easiest way ever to fine tune bass surpassing 16Hz at reference volumes from the comfort of your favorite seat.
For added convenience, 2-way feedback shows updates in real time on both the app and subwoofer interface and 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.
A subwoofer capable of creating such extreme levels of sonic energy requires a formidable cabinet design. The PB16-Ultra is built 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.
