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.

Customer Reviews for SVS SB13-Ultra 1000 Watt DSP Controlled 13" Compact Sealed Subwoofer
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!
My setup isn't anything too elaborate or extraordinary. I have a Sony ES receiver delivering around 100w RMS to a full matched set of Klipsch Reference series speakers in a 5.1 configuration. This sub-woofer blends in nicely with my setup (after some tweaking) and I use it mainly for movies and video games, and occasionally for 2.1 music listening. It took a good 2-3 weeks to really break it in and get the placement just right, or at least close enough to just right while still maintaining a high WAF (wife acceptance factor) with regards to placement in the room. After 4 months of playing with it and doing some critical listening, I'm happy to say I'm extremely satisfied overall with my purchase, save one issue I'm going to detail below.
My issue - My only gripe is with the main power cord receptacle (where the female end of the power cord connects to the sub-woofer). It just doesn't seem to firmly sit in the main AC receptacle, and I've tried several other cords I have laying around. Simply stated, it just feels loose instead of being really tight like the receptacle on a computer power supply for instance. I have had the cord come slightly out of the receptacle at times, but it hasn't fully come out at any point. The power plug hasn't fallen out, but it really stands out like a sore thumb against the near perfect construction of the sub-woofer in general.
My suggestion would be to use a three prong power inlet instead of a two prong, even if the ground pin in the receptacle isn't connected to anything. I think this small change would make the receptacle hold the power cable much more solidly, and then I would say the construction is absolutely perfect.
