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.

It's worth it
Well I'm happy to say that I'm a proud owner of the sb-16 ultra. I decided to upgrade from the sb-4000 to see if the ultra had the extra steam needed during movies with DEEP LFE information such as Blade Runner 2049, Batman, Venom etc. and surely it does! This thing has to be more than 300rms watts difference. I'm seeing a 4dB increase in my room from the sb-4000 and that's massive! It's not to say the sb-4000 can't hold its own because that subwoofer is impressive in its own right hands down, but if you like to listen VERY loud and want a subwoofer that's more than solid than I'd recommend the ultra line up. I haven't has any issues whatsoever with ultra, it's clean sounding, its extremely fast for a woofer of its size. Doesn't matter what you throw at it, it'll keep up. from heavy metal, pop, hip hop, jazz. it will handle them all with finesse not to mention its a lovely looking subwoofer. My sb-4000 was ash, which looked good but this time I went gloss and boy does it look elegant! Would I say get this product? YES! I'm using the XLR input with Straight Wire Rhapsody 3 XLR to XLR cable and imo the sub is tighter and quicker versus the RCA Blue Jean cable I was using. Anyhow, buy the sb-16 ultra you won't regret it. Its worth it!

Wonderful subwoofer (tip: in large spaces, try both types of feet)
Our living room is where bass goes to die. It's part of an open floor plan entry/kitchen/living/two open loft bedrooms area totaling about 1,400 square feet with ceilings averaging above 9', with three openings to the other 1,300 sq ft of the house. It's too much cubic volume to pressurize with bass from one subwoofer.

Despite this challenge, the SB16-Ultra produces precise, rich, deep, satisfying bass from a listening position about 12' from the speakers and centrally placed sub (rolled off at 45 hz, 18 db/octave to supplement my near-full-range stereo speakers). We listen to a wide range of music including jazz, pop, classical, and hip hop, often at fairly high volumes, and the SB16 Ultra always delivers.

The only real surprise was finding out that the stock hard (nylon?) conical feet that came with the subwoofer worked MUCH better in our space than the optional $50 rubber feet. The sub has just the right degree of palpable impact with the stock feet. I put on the optional rubber feet, and the impact of the sub DISAPPEARED in our large listening space. It didn't matter how much I turned up the gain; my wife and I were sad. The stock feet went back on and all was well. So please don't assume that the optional rubber feet are best for a large space; the stock feet may be best. Happy listening!

SB 4000
I first purchased the sb 16. What an incredible sub. It was a bit more than i needed. The folks at SVS suggested the SB 3000. I tried it and it wasn’t enough for my requirements. SVS suggested the SB 4000 and omg it is perfect. The cool thing about these guys is you can call them and work through your needs. Very customer focused, best service I can remember. They helped me set up my sub and it sounds perfect.

Good accuracy
The sub is good and I am comparing it to other high end subs including the paradigm Servo 15 V2. I have two and especially like the app and the ability to use one remote. I can ensure phase angle, roll off and slope are identical. It has brought out the texture in bass lines.

Ultra is right
Matched this sub to my recently purchased PSB Stratus Gold i and used the recommended settings from SVS that matches it to these speakers. Flat out, made the sound huge! Crystal clear, match perfectly and has contributed to exceptional sound from my system.

The top of the line SB16-Ultra
Once you get to the top, if's hard - next to impossible - to go back. The SB16-Ultra is the pinnavle of "big bass" and holds its own against any and all competitors, and puts most of them to shame.

With the power this baby brings, there is simply no way to beat the bass this sealed unit pumps out!

SVS SB16-Ultra, the ear tickler ??
The SVS SB16-Ultra Subwoofer is an amazing piece of Audio equipment, right off the box you see the quality and dedication that went on the production of this “BEAST” of a Subwoofer. The materials that are used on these Subs are of high quality, I know because I took a peak inside, from the rear of course, I took great care when removing the amplifier, I did used an old “credit card” in order not to damage it’s pristine and shiny look and to avoid any scratches to the finish, I couldn’t contain myself but I had to see the entrails of it for myself, the cabinet is well made, thicker than other Subs that I’ve owned before, the center reinforcement as well as the overall cabinet gives it’s sturdiness and rigidity. I was amazed the first time I heard this “BEAST” I’ve felt and love the authoritative sound and punch this Sub delivers, I was missing out much of my music and movie content with my previous Sub. SVS SB16-Ultra is the new “Boss,” and a game changer. My neighbors ears get tickled ?? every time I listen to music or watch heavy Sci-Fi action movies. Too bad for them, I enjoy every minute of it! ??????

By the way SVS, thanks for the extent of your customer care and for the $200.00 refund, due to a price reduction I was not aware of.

Thanks SVS, you “REALLY” did it again!
