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

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.

Thank you for a great product. The SB, Ultra 13 Sub is just what you say it is. It matches up great with my Magnepan 1.6s. There is nothing not to like.

Unreal value for money. Highly recommended for high-end systems.
Got an outlet SB13-Ultra subwoofer at a great discount. Since I have a toddler at home, I don't mind getting an item with a few scratches at a discount, there will be more to come.

The sub arrived on time and, to my surprise, there was barely any visible scratch. Performance is also amazing, I set the HPF at 40Hz and volume to -25db so it blends amazingly with my (tube-powered) Magico S5s. I'll continue with room analysis and play with the parametric equalizer, though I am more than happy with the simple setup I currently have.

Value for money is just unbelievable, nothing comes close to it in my sound system. Highly recommended.

Excellent Sub
This is the best sub that I have owned. It is paired with B and W
803 Ds and B and W center channel. The blend among the speakers
and the SB 13 is exceptional as is the pure power of the sub.
The system is run by a Yamaha 2020.

The quality of the construction of this sub is simply the best that I
have seen. All and all a great speaker.

The SB13-Ultra by SVS is Outstanding
The SB13-Ultra by SVS was a replacement for a Sunfire TS-EQ subwoofer.
I was initially attracted to the SB13-Ultra by the universal praise of the product at numerous videophile and audiophile websites.
When I logged into the website, I was able to match my Phase Technology Audio Speakers to the SB13-Ultra. The site and staff were then able to select the subwoofer settings for my Denon AVR 5803 receiver.
I ordered the subwoofer. It was promptly delivered in secure packing in a few days. I unloaded the box, plugged in the subwoofer to my system, made the suggested settings, and voila...phenomenal panoramic sound in my system!
I did not need to call the SVS team for support as the suggested settings worked flawlessly. My audio system now has the best soundstage I have experienced in over 25 years of watching movies and listening to music.
I have waited four months from my date of purchase to write this review...the SB13-Ultra
continues to exceed my expectations. It is the most important feature of my seem-less 7.1 audio system.

Perfect supplement to my 805's
This sub exceeds my expectations! I wanted a little more punch in the low end from my 805's in a two channel music environment. The bass is so tight and precise that it is a seamless fit. I've been listening to a lot of music over again to experience the revamped system and all I can say is wow.

Extremely Satisfied
I purchased two SB13's and will never go back to one subwoofer again. I am actually rewatching my collection of Blu-rays as I didnt realize how good 7.1 really is. I also want to recognize the excellent customer support i recieved while setting up the subs using Audyssey on my Sound processor. The fine tuning after the Audyssey setup made all the difference!

The svs sb ultra 13 is so good I'm soon will be buying another one to compliment my very fast Martin Logan CLS in my listing room. The one I purchased last month is doing a fantastic job with my PSB theater system. Not a better deal out there for this level of performance .

I really didn't expect the addition of the SB13 Ultra subwoofer to have THIS much impact on my system. It's not like I didn't have an excellent subwoofer before.

Boy was I surprised. Sure, I expected the surround sound to benefit by the more powerful bass, but the real joy for me was how much the SB13 Ultra enhanced my music. And not just the bass performance, the entire experience of listening to my music was made better. Any music lover knows the euphoria that accompanies hearing familiar music in a new way. I am still working through all my favorite albums and enjoying them for the first time all over again!

Thank you, SVS for an amazing product!
