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.

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!

Trade up experience
I took advantage of the trade-up program and moved from my SB3000 to the SB 16 Ultra. I'm totally happy with the Ultra - and Nancy with customer service made the whole experience surprisingly smooth. She was awesome from beginning to end. I really like and respect the way SVS does business.

Never cared to write a review; that's how good this one is!
No, I haven't been paid or even offered a discount for this review.

These people do their jobs out of love; money cannot buy the care, support, and dedication they have been showing over the years.

Now, when it comes to the sound, please, use the SVS interconnect cable, even if you believe it's snake oil. I have been building amps/speakers since 1978, and I can assure you, you'd have to pay 10x+ for anything marginally better. If you have only $10k in your system, this is your place to buy. For $300k+, you might want to spend more, but I'm not sure that all the line conditioners in a city will not take the dynamics out of your system in return for some relatively-stable sound image... You whole house, including the breakers would need to be re-wired and even at that point, nothing will be guaranteed.

The parameters of this sub are actually accurate. If you experience any lag or reverb, it's your amp.

Ultimately, it's up to you, but SVS also offers a 45-day unconditional return policy, which only bottom-feeders would take advantage of, but once you try these subs with the right interconnect cables on the right amp, you'll find this is a keeper. Placing it is another challenge, but in general, you want to make sure it's directed towards the longest end in your living room (or wherever your listening place is) in order to give the bass the longest way to run its course.

No 45 day trial necessary after a week and getting it dialed in this SB-16 Ultra is not being returned. Extraordinary how this one component can transform an entire system into a movie theater and live soundstage music performance. I thought my previous Klipsch R-115SW was good but this SB-16 is on a whole different level and quality of bass. My jaw drops like it never has before on movie scenes I’ve watched many times before and songs I’ve listened to numerous times. Even at sheer high volumes the SB-16 Ultra keeps asking for more with almost unlimited headroom. By far, the best purchase for my AV system.

Svs for life
So this isn't my first review and this is far from my first SVS purchase. I started with two pc2000s 6 years ago and ended up with two sb 16 ultras a few years later. Well life happened and I had to say goodbye to them. Started back on my journey 6 months ago and started with 2 pc2000 pros again. Traded up to pc4000 and traded up again to sb16 ultra. Very long story short, I ended back where I was a couple years ago and couldn't be happier. My experience with the SVS team has always been of the highest calibur; I mean it, I haven't had better customer service with any other company ever. I remain a loyal customer of svs for this reason and also top notch quality of what I can only describe as the deepest, cleanest bass I've ever heard. A winning two-punch combo.

Unreal performance
I calibrate home theaters but don't often do so in those utilizing SVS subs. In my most recent job, there were 4 SVS SB16's installed - one in each corner - and a not very large room. I used REW to align the 4 subs and decided to see what (in this case) Audyssey could do with no help (e.g. PEQs in the subs or externally). Results: RULER FLAT response from about 115Hz down to (drum roll please) 11Hz. Room gain is our friend. And sonically, it was WAY better than I expected. Tight. No bass bloat. No "thumpiness". This theater was properly passively treated. We played some demo cuts from various movies at or above reference and the subs never made any nasty sounds. I have recently purchased and SVS SB-3000 to be used along side a higher end "soundbar". After the experience noted above, I can't wait to hear the results.

So worth it!
Unfortunately, I did some indecisive waffling with regard to this purchase. I started out buying the 2.1 prime wireless setup. Considering its specs and price point, it was pretty awesome. Shortly afterwards, my brother convinced me that I should get the 3000 micro subwoofer instead of the SB-1000 pro it came with. I pondered that for a bit, but, as he is the true audiophile in the family, I decided to follow his advice despite the added price tag. You will notice of course what this review is supposed to be about ??. After getting everything set up I decided that, while awesome, I wasn't quite satisfied yet. 2.1 with the micro sounded great....but I could do even better said my brain. Thanks to the very generous return policy and amazing customer service that SVS seems to have, I am currently enjoying my final rendition of music and movie awesomeness. I have the Ultra Surround setup paired with the SB-16 Ultra sub all powered by a Denon X2700H receiver. This system is the best I have ever heard much less owned. And for a good deal less than I would have paid for a few of the other brands I considered.
