Product Information

One Subwoofer to Rule Them All

An unrelenting passion for awesome bass performance and engineering perfection guided every aspect of the SB16-Ultra subwoofer’s design. Groundbreaking technology, rigorous design, and extreme testing in real world and laboratory environments allowed SVS to achieve massive output levels, extreme low frequency extension, near-perfect frequency response accuracy, and pinpoint transient response. The culmination of all SVS design advancements, SB16-Ultra represents the greatest leap forward in performance and innovation since the inception of subwoofers.

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 SB16-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 78mm peak to peak Xmech excursion (65mm 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 SB16-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 SB16-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 SB16-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 an equally robust cabinet design. The SB16-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.

Comparing with JL Audio Fathom f112
I am still early in the comparison process, but so fat the Fathom is superior. I am still recommending bases on price.

Clean Deep Sound
End game for sealed home use. Clean, tight, deep base. I have an open 1st floor plan with 10 foot ceilings and getting very good room gain.

What My Home Theater Was Missing
I've agonized over purchasing the SB16 Ultra for several years. I already had a decent 12" sub and some B&W 702S2 that seemed to deliver impressive bass. I finally made the decision after discussing with a SVS Tech and moving into a home that had a decent place to put it. Got everything hooked up and tuned then proceeded to watch one of my favorite movies Bladerunne 2049 (4KUHD). Eye popping is an understatement. Not overbearing or boomy. The word that comes to mind is 'concrete'. Solid. What I didn't hear, I felt through my feet and recliner. There wasn't anything it didn't shake off (or shake). No noisy excursion or port noise. Just an immersive experience. Sad that I waited this long to enjoy something this good.

It is amazing!! exceeded my
It is amazing!! exceeded my expectation. An amzing sub! Hits so hard if you want it to, Call Of Duty is so intense with this Sub. My wife said “ turn it down, someone is going to call the cops!” “ They will think there are real guns and exslposians!” And I cant forget to mention how beautiful the sub is. a work of art.

SB16-Ultra.... awsome bass.
I bought a pair of Wilson Audio WATTS/Puppies with a Krell amp and pre-amp. If you have ever listened to these speaker you would be amazed by the clarity of sound that they produce. I had a polk 12"sub for my surround system and when combined with this new system, that sub sounded awful. The polk could not keep up with the Wilson audio speakers. So the search for a new Sub began. I didn't want to spend another small fortune on a sub. I already owned a pair of Prime Elevations and decided to call SVS and see what they had to say. The person who helped knew my system first hand and instantly recommended the SB16-Ultra.... So I ordered it. When I I saw the box it came in, I was afraid it was going to be too big for the place I had available! But fortunately fo me the Sub fit perfectly. This is not a small speaker, but it should not be. It is well built and solid. It was Love at first sight.

The App and its ability to fine tune the woofer was CRITICAL for me. The SB16 was placed forward of the Wilson Audio speakers. I know this is not ideal but that is what I had to work with. But the saving grace was that I could change the phase of the woofer. After hours of listening and placement, I was able to match the timing of the bass with that of the Wilson's..... and OMG! the sound was phenomenal. The lower end of the system came through in a way that I can only describe as moving.

I had hooked up the speakers with the same RCA cable i was using before and thought that it was not quite perfect. Something was still off. I ordered a SUB4 woofer cable from Morrow audio. The speed and clarity of those cables took these woofers to a place i can only describe as sonically accurate. I could not only feel the bass, but more importantly I could hear it with immense clarity. The combined cable and SB16-Ultra woofer is Fast, precise, responsive, articulate and accurate. When the bass note is played, not only can I hear that note, but i can hear the resonance and subtle sounds imbedded in musical instruments. This additional clarity and ability is what allows a system to go from great to awesome. For the SB16 to match up precisely with the mains and all be in phase is nothing short of miraculous.

The SB16 is fast and accurate. It is capable and responsive. It is articulate and clear. It is everything a Sub should be. To be able to hear and feel the bass precisely at HIGH sound pressure levels is what was missing from my system. It is no small feat what this woofer is doing. I give this woofer the highest recommendation. Take the time to uses the APP to optimize the woofer to your setup. Use really good cables, you will hear and feel the difference. My only wish is that I had a bigger room so I could add another SB16!

Awesome Sub
Bought the SB16 and set it up. At first the volume was really low. I called support and was able to reach someone right away. They were able to work with me on the settings on my receiver. The Bass on this amazing music and movies sound great.

The Best Subwoofer For The Money
I have been using the SB16 ULTRA for about 3 weeks.... I use it mainly for .1 LFE for home theater and to add extra bass to fun hip hop, rap, and techno music. I corner loaded the sub in the back of the room...OMG! AMAZING! My sound system is incredible since the addition of the 16 Ultra.
I recommend that everyone with ears get their hands on one. This is the best subwoofer for the money, anywhere.

The SB16-Ultra is great. I
The SB16-Ultra is great. I was worried that the sealed version was going to lose a lot of very low frequency response but I was totally wrong! This thing hits everything very smoothly with no signs of stress, both in home theater settings and music. I also replaced a double 12" sub and a second single 12" sub all with this one sub... and I have more sound that is very crisp. I can't say enough...

Elephant in the room that you don't see.
This subwoofer is exactly how sound should be. You would never know that the powerful & satisfying low end effects can come out of a 20x20 box of joy that almost disappears into the shadows. The bass is so authoritative and subtle at the same time. It can be very discreet while reproducing music mix in movies and then slam your face when stuff blows up. Was watching Greyhound the other night and felt like the Captain on deck when the torpedos struck their targets. I had originally used the PB4000 but felt in my room that it was too "ringy" if that makes sense and lacked the tightness I wanted from a bass note. These subs really compliment the main speakers well without you even knowing, just a real even balanced tone from mids to lows. I am waiting on my second SB16 to complete my 7.2.4 Atmos setup!
