Product Information

Heroic Performance; Black-Tie Elegance

Are there 17 square inches in your home to make room for the most critically acclaimed subwoofer on the planet? The SB13-Ultra 1000 Watt DSP Controlled 13" Compact Sealed Subwoofer is the most popular Ultra for more than its modest stature alone. This flagship of the SVS sealed models delivers superhero levels of power, detail, speed, and musicality. Yet, disguised in an elegant and compact cabinet, it goes practically unnoticed in any décor, until it's called into action. You'll quickly find the SB13's reputation is well deserved and its value unparalleled.

Sledge Amplifier STA-1000D

The Sledge STA-1000D amplifier is a perfect match for the Ultra 13 driver, packing 1000 watts of power and sophisticated DSP control. Comprehensive and extensive menu options are accessed via an intuitive single-knob interface and an easy-to-use LCD display. This will make your setup and integration with home theater or stereo system quick and simple.

Sheer power alone is not enough. The SB13-Ultra's amplifier equalization curve has been expertly optimized. Its roll-off is gradual, transient response superb, and group delay extremely low. This roll-off profile makes the most of available 'room gain', so that under optimal conditions, the SB13-Ultra can extend in room to 15Hz or deeper. Even more, these characteristics make it ideal to pair with other SB13-Ultras for multiple configurations.

SVS 13.5" High Output Driver

To equip the SB13, SVS's audio engineers started miles ahead of other subwoofers. Their advantage was the famed Ultra 13 driver, which they then optimized for a sealed application. They revised the motor geometry, added a unique voice coil, and added a custom gap extension plate. The result is a sealed subwoofer that delivers higher thermal power handling, more symmetrical force/displacement profile, lower distortion, and increased linear stroke. Only SVS engineers could start with the Ultra 13 driver, and only SVS engineers would push the envelope this far to deliver the clean, deep low end of the SB13-Ultra.

  • FEA-optimized motor with copper shorting sleeve to reduce gap induction and distortion
  • Unique and optimized bifilar wound, 3" diameter, ultra-high-power aluminum voice coil
  • Unique gap extension plate for additional linear stroke and reduced distortion
  • Dual linear-roll spiders and stitched parabolic surround for extreme excursion capability
  • Ultra-light and rigid Rohacell composite cone to provide excellent transient response




  • Dimensions (H x W x D): 17.4" x 17.4" x 18.5"
  • Weight: 92 lbs.
  • Driver size: 13.5"
  • Frequency response: 20 - 460Hz ± 3dB

Don't let the price fool you!!
Let me start by describing my reluctance to buy/audition this product. I didn't think for one minute that a subwoofer in this price range could convey the reallism I had searched for within movie soundtracks while offering the finesse I yearned for, for my music. Boy was I was wrong!!! I received my first SB13-Ultra near the beginning of last year. I placed the sub in my large main home theater (as recommended by SVS) and allowed the sub to break in for at least 24 hours. I then callibrated my system and sat back for a test drive. WOW!! The sub brought to life a sense of "being there" throughout movies, but was still able to provide the tight bottom end I had sought with all genre of music I love most. Forget the "45 day guarantee"...this sub now had a permanent new home! With Christmas approaching my quandary of what Santa could bring me was soon fulfilled by another SB13-Ultra!! Thanks Santa!! As before, I placed the sub, allowed break-in, calibrated, and hoped for the best. Ok...two of these beasts will pound you silly with brutal taut low end bass!! My wife and I were giddy like school children, wanting and needing to play through our entire movie/music library!! Two of these incredible subs have brought a sonic fullness to everything we've thrown at them. So, if anyone out there is on the fence as I was, BUY this sub (or two) if you can. You will not be sorry. A wholehearted recommendation for this sub and for SVS's customer support!!! Thank you SVS!!

Incredible Subs from a special company
After owning one of the original SVS cylinder subs for years, it was finally time to upgrade. I have a large room (20x24 with 14’ peaked ceiling) and two SB13-Ultra’s are simply amazing. Effortless, musical and very powerful. I personally like the fast attack transients of the sealed sub and given two of these things there is no lack of SPL or low-low end. They go perfectly with my LS-6’s, LS-C and RS750’s (surround). I also want to note that as SVS has grown, I’ve never once felt like the company lost any value in my being a customer - something one doesn’t see that often nowadays. An easy 5/5 rating across the board from me (and I’m pretty picky). Well done SVS!

After much research and debating on which subwoofer to choose for my system, I finally settled on the SVS. The 45 day money back guarantee was a determining factor in my decision. I have had the subwoofer for two weeks now. It is AWESOME. I am very satisfied with its performance. I have been very happy with all of my interactions with SVS company. They have been very helpful in all of my interactions. This is a very high quality product and the perfect addition to my system.

Well, all I can say is WOW. The sub was very easy to integrate into my system. It literally disappears into the sound stage. The bass is tight and well defined. Bass solos now sound like notes, instead of a low undefined rumble. I have only had the SB13-Ultra for five days and all my spare time is being spent listening to the music that I have never known existed on my cds. It also looks beautiful in the high gloss finish.

This is what a Sub is supposed to be.
I have had my Ultra13 for a couple of years now, so, this is not a 'fanboy' knee-jerk reaction. I use the '13' strictly for music, and I do put a lot of 'passion' into my system, and having my system sound realistic to me is important. This Sub is just what I have always wanted, and at the right price. I am currently using it to cover the under 300 Hz area, along with my Horns, which do the 300 Hz up region. So, this has been a wonderful test of the Ultra's musicality, not just the 'sub' Hz regions. Drums, upright bass, electric bass and all other instruments are simply perfect. Thank you SVS, it is nice to find an audio company that delivers the sound I have desired, while pricing it's items at a completely reasonable price.

The Search for Perfection is over!!
Not sure how I came across this site, but consider myself extremely lucky to now be the proud owner of two AMAZING SB13 Ultra's. I started out reading the specs on all the different SVS subs and trying to figure out how I would convince the wife a SVS sub was absolutely necessary. I almost didn't purchase thinking the competition must be better because it costs more. I read through the reviews on this site, other AV forums, and even got sucked into hours of You Tube videos. I decided I should at least have an open mind, so I scurried on down to Best Buy where they had a Martin Logan Dynamo 1500x and the SB13 Ultra. Even though the 1500x has a bigger driver, the SB13 had more pound and cleaner transitions. It took me about 30 seconds to realize the SB13 was something special, and I purchased one a few days later. I have a medium size room, and I was a little worried the SB13 just wouldn't have enough of an impact to really get those hard deep notes in action films. Once i got it set up and dialed in I immediately knew I had chosen wisely. After listening a little, I realized I enjoyed the pounding bass so much I basically turned it up to about 80%. When doing so, there was kind of a lingering annoying bass sound overpowering my speakers. I fiddled around with the AVR and was able to increase the gain on the lower frequencies, and lower the gain on those frequencies above about 65hz. That did the trick and now I get more impact with no background bass noise. It blends so well and really allows you to enjoy all genres of movies. My experience was so great, that I just purchased another one for the family room. I have a feeling the SB16 will be on my Christmas list this year!!

Amazing Sub with Small Footprint
I was turned on to SVS by the manufacturer of my in-ceiling speakers (Noble Fidelity). He indicated that SVS has some of the best subwoofers in the industry for reasonable prices. Although I really wanted a ported subwoofer for my in-home theater, I couldn't get my wife comfortable with the sheer size of the box. We settled on this smaller sealed subwoofer, but opted for the top-of-the-line model, and we couldn't be happier with it. As SVS suggested, after hooking everything up and calibrating it via Onkyo's Audyssey, I called SVS customer support to make sure I had the optimal settings to get the most out of the subwoofer. The representative was very friendly and knowledgeable and confirmed I had everything right where it should be. The sound and force from this subwoofer is unbelievable. I've never experienced such clean bass as this produces. I'm still tweaking the power up and down to get it just right as it truly is possible with this subwoofer to have too much bass (although for movies that threshold for me is pretty high). We are hearing bass in songs/movies that prior subwoofers failed to output. You literally feel the force of this subwoofer in your body and movies become life-like. Although more than I ever contemplated spending on a subwoofer, I feel this purchase will provide great listening and value for many years to come. I would highly recommend this subwoofer for anyone looking for top-of-the-line audio.

5 star product, 10 star service!
I purchased a pair of SB13-Ultras 5 months ago and wanted to spend several months living with them before sharing my thoughts. The short version: My wife and I absolutely love them and consider them a true bargain.

I sent an email to SVS, prior to purchase, inquiring about which subwoofer might best fit my existing system. To my amazement, Ed Mullen (Director, Technology and Customer Relations) responded to my email within a few hours and asked me to call him. I called Ed and was blown away by the amount of time that he spent with me, on the phone. Ed was genuinely interested in what goals I was hoping to achieve in adding some subwoofers to my system. Ed asked me to send him specifications on my system and, if possible, photos. I did as Ed requested and he was able to make an informed recommendation, based on my actual needs. As stated above, I ended up ordering a pair of the SB-13 Ultras and it has been sonic nirvana ever since. Kudos to Ed for the outstanding customer assistance. I even received a follow up email from the Gary Yacoubian, the president of the company! Wow! These guys actually made this customer feel like I was important to them. I have never experienced such excellent customer service (especially considering that there was never any pressure to buy one of their subwoofers; they seemed genuinely more interested in making sure that I was making a rational decision about adding subwoofers to my existing system).

Ordering was simple and intuitive (online). The subwoofers arrived very quickly (a few days) and were extremely well packed. I'm 5'9" and 165 Lbs and had no trouble (with the help of a dolly) getting the subwoofers downstairs to my media room and unpacked.

I opted for the piano black finish and it is exquisite. Aesthetics are a very personal thing, but these subs look beautiful to me. The fit and finish of both subs is flawless. My wife and I are empty nesters and have no pets, so in five months the subs have not acquired any fingerprints or pet hair. My wife dusts them occassionally with nothing more than a dry lint free cloth. They still look brand new.

The need for the subs stems from the type of listening that my wife and I do. We enjoy watching movies at theater volumes and our media room is a very large room. We needed greater volume output and deeper lows. We do also occassionally enjoy music through our system, but it is primarily used for Home Theater.

Setup was fairly straightforward. The system is as follows: Both subs are connected to a Marantz AV7701 pre/pro via 15' XLR cables. The subs were added to an existing 7 channel surround Home Theater system (although, the Center Channel is split to run two Center Channels). All front channel speakers are being driven by Emotiva monoblocks and the surrounds are being driven by an Emotiva XPA-5 amp. Front speakers are large full range speakers. In spite of plenty of power in the electronics and Large full range fronts, we just weren't quite satisfied with the output of our system prior to the addition of the subs.

Placement was limited, due to factors beyond our control. Both subs are located at the front of the room near the mains. The left sub is in a fixed position and can not be moved. I played a little with the positioning of the right sub and ultimately decided on the original location (where I had first placed it) next to the right main.

The subs have changed our Home Theater experience in a measurably satisfying way. I had considered the purchase of tactile stimulators, previously, but no longer feel the need for them (after adding these subs). We achieved all that we had hoped to with this pair of SB13-Ultras: deep, rich, solid, powerful (you can feel it in your gut) bass that is only there when it is supposed to be and never feels like it is calling attention to itself or "in the way," of the experience.

This pair of subs has replaced an Earthquake Supernova 15 mkV (which we really liked). Wow, we never knew what we were missing.

For us, our money was well spent. I only wish that we had purchased these subs sooner.

My thanks to both Gary and Ed for their exemplary assistance and to all the designers involved in bringing this amazing sub to market. My wife and I are daily enjoying the fruits of your labors!

Incredible Subwoofer for Music and Movies
I originally purchased dual SVS SB12-NSD's on the Black Friday special to use in my basement theater (18x18x8). I figured two of them would be great. After a few days of continuous listening to music and watching a few movies, I was not really impressed. The bass was quick and punchy, but there was little extension to lower frequencies. I didn’t get the feeling of being punched in the chest. If I had to describe their performance, it was more like a hard vibration than it was smooth and detailed. On Cyber Monday I got a steal on two SB13 Ultra’s and was blown away by their performance. Sure, even on their sale they were 2.5 times the price of the SB12-NSD’s, but I was tired of trying different subwoofers…so I decided to just put my money where my mouth was and go for one of the best. I listen to a lot of music, but still wanted a subwoofer to perform extremely well for movies. I initially had one SB13 Ultra set up in the front of the room, to the left of my right main speaker. The performance was incredible, but I wanted to balance out the bass in the room a bit, so the second really helped. After running Audyssey on my Denon receiver, the volume on the subwoofers was pretty low. The receiver set them to -12dB when leveled out. Read the instructions from SVS…increase the subwoofer level output on the receiver before you increase the volume level on the actual subwoofer. The bass will be much more detailed and smooth. I mentioned the SB12-NSD’s were a bit hard sounding, while these are very smooth and have much better low end extension. You feel these in your chest. The SB12-NSD’s rattled the walls and everything from the vibration, while these rattle much less as they deliver much more smooth bass. I’m sure the new SB-4000’s are even better…so don’t hesitate to buy the SB13 Ultra if you can still find them, or the newer SB-4000.

I had one SB13 Ultra arrive with a dented grill, so I contacted SVS and they sent a replacement to me the next day, no questions asked. Incredible customer service to support their excellent products.
