Product Information

An Incomparable Bass Experience

An unrelenting passion for awesome bass performance and engineering perfection guided every aspect of the PB16-Ultra subwoofer’s design. 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.

Massive New 16" SVS Ultra Driver with Unprecedented 8" Edge Wound Voice Coil

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” driver is the 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. 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 Xmech excursion (82mm Xmax) and the highest levels of motor force and palpable SPLs. The light and rigid 16” 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.

Stunningly Powerful, New Sledge Amplifier with Fully Discrete MOSFET Output

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” 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.

Innovative New Smartphone App for Subwoofer DSP and Control

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.

Acoustically Inert, Rigidly Braced Cabinet

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.

OK sub - better options for audiophiles out there
To get things off the start - these subs are loud - they play tonally fine. They are a little slow and muddy on reverb, along with a bass drop off with substantial power loss between 15-19hz which is unacceptable. I shouldn't have to increase volume levels to maintain a static SPL across all volume levels. I have not had this problem with superior subwoofers like the Axiom EP800 or JBL Gotham which maintain incredible pressure levels in the infrasonic range Was very disappointed with their output below 18hz-19hz. Considering the size and weight of these, they definitely dropped the ball with their amp and digital processing Great if you need loud, if you want accuracy and proper reproduction look elsewhere Tested with: -Kef Reference 5 tower mains -Emotiva Reference AV -860 sq ft square listening room 10ft ceiling

You won’t regret this purchase
Having had some typical name-brand subs over the years, I thought I had some good equipment. As I paid more attention, I started to notice all the distortion and lack of definition in sub-bass with the usual suspects when it comes to subs. I finally decided to step up to the PB16-Ultra. Only regret is not doing 2. The sub can be un-menacing, just adding to and filling out the sound stage. Or you can go animal-style and warp your walls and reality by cranking it up. It can do it all with ease. I’m hearing things from my music and movies I never noticed before, oh - and I’m feeling it too. The quality didn’t stop with the subwoofer either, it continued into customer service. Very responsive, very helpful. Shipping was perfect too.

simply the best, super, brilliant, stunning!!
These two subwoofers, used together with DIRAC sound / room correction are simply a revelation. The English language simply lacks words to describe the effects they have on your stereo and home theater system. Even tracks that seem to have no or little bass have added "air" and sound "cues" that help recreate the recording space. The recording room (or auditorium as it were) is eerily transposed into your listening room at home. These go deep......far, far below the limits of human hearing......and they do this at stunning, simply astounding dB levels. Actually, you may want to have a structural engineer look at your house after using these for a few months, they move that much air (just kidding). These will startle and terrify small children and animals. Be prepared. Damn the torpedoes, full speed ahead, and make sure your valuable china and crystal are pinned down securely.....even three or four rooms away. "The Boat" (the great German submarine film) is actually almost painful......especially when the depth-charges go off for the first time. You (and your neighbors) were warned........

First, I should note that I very rarely write a review about any product that I purchase. That being said, I have been enjoying high quality audio products for almost 20 years now. If you are a beginner or just someone that isn’t familiar with how to properly setup these subs and tune them to your space, please call a professional to help or even do it for you. SVS Customer Service is the best, but they are limited to the help they can provide over the phone. These subs are precise. They hit with authority and they command the space they are in. I highly recommend buying at least two. Dual subs are essential and if you are considering these subs, budget shouldn’t matter.

Purchased 2 of these, definitely feel the bass in music, movies, whatever the case may be. Extremely impressed with the sound, no distortion regardless of volume level. My setup is 7.2.4, all SVS speakers, Denon 6700 AVR, 212" screen in a 26' x 52' room with 13' ceiling. Simply amazing and thoroughly enjoy the SVS products. Highly recommend!!!
