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.

Unbelievable sound quality. Its bass
Unbelievable sound quality. Its bass you can literally feel! Strongly considering pairing it with a second one, two subs has always been better than one. It's just that one already shakes my house pretty bad ;

Exceeds my expectations.
I was expecting lots of thump, which it delivers! But I wasn't expecting such incredible sound. I didn't know this sound quality existed within the recording.

Why doesn't everyone have two of these?
After moving to a larger space (50,000 cuft barndo livingroom) we needed more power than our two 12" ASW 650s could provide. I did not expect these to be as much of an improvement as they are. SVS knows what they are doing with the 45day return policy, I won't be giving these up. One complaint: The front grille is super-cool, but really invites 2 year olds to stuff toys down the front hole. I think I'll be building some sort of cage.

Very nice Subwoofer
Clean deep bass, and highly customizable to your listening needs. Great for the home theater or your music collection because this monster can be tamed sonically to play nicely when desired. However, if you want to shake the foundation of your home, as I usually do, this baby will happily oblige. Great purchase!

Excellent Purchase
I replaced a 20 year old velodyne 15” with the SB16 Ultra. The SB16 is smooth, crisp, with a rich low end. I couldn’t be happier with this purchase.

It's a beautiful thing
I purchased the PB16 Ultra a couple of months ago, but once it was in my house its dimensions were a little larger than what I was expecting. I worked with SVS support to swap out the PB for the SB; which truthfully suited my purpose more closely than the PB model (I'm more of an audiophile than a movie buff). My interaction with support was great. They were responsive and extremely pleasant. A couple of days later the PB was picked up and a couple of days later the SB delivered.

The SB16-Ultra is amazing!!! The sound quality is incredible. The fit and finish is dazzling! I can't wait to get the 500hrs of listening in for the driver to warm up and break in. My friends are blown away by the sound and feel, no doubt my neighbors do not appreciate it. Bottom line, awesome piece of musical equipment!

Still Impressed
It's been a month since I wrote my review. I felt compelled to submit an update. The SB16-Ultra has breathed new life into my system. I have always been very happy with my Theil CS3.5s and the sub I have been using, but the SB16 has taken the system to a new level. I am finally getting the balanced deep bass I have always craved. I find I am coming back home to my stereo and listening to it as much as I did when I first set it up. I am now wishing I had added this sub years ago. After more listening, I am finding the significant investment in this sub is more than worth it.

The Ultra sub woofer
I’ve had my Ultra sub up and running for about three weeks. Subs are usually very hard to integrate into a room and blend with an established stereo and movie system. With my stereo system the Ultra enhanced the music, not only with deeper bass, but by bringing out more of the auditorium ambience. The music is now much more inclusive. You really do feel as if you are almost there. With movies, again the bass is deeper but very nicely blended into the movie. It really adds realism to the movies. Again a nice improvement to the movie viewing event.

What I think is the best part of owning an Ultra sub is the customer service. it is the best Service I have ever dealt with. Ryan Wright is an excellent representative for Svsound. He, with many exchanges of emails, helped to set up my sub in what is for me a complex installation. Ryan had me try something that I never would have thought was a good idea. He was right. My system is much better because of his suggestions. By the way, Ryan approved a military discount. His Marine Corps appreciation was a very nice gesture. To conclude, this is a great sub. Try it in your system and work with Ryan to set it up. You’ll be glad you did.
