Box Subwoofer Ultra Series
Out of stock. Check out news about the new SVS Ultra subwoofer family coming soon!
This SVS was the most eagerly awaited new model we've introduced. For months prior to its launch, customers eager to try the world's most powerful and most refined powered subwoofers just wanted to know two things about the PB12-Ultra/2.
When, and, how much? With new cabinets, it's better than ever.
While it's hardly inexpensive, the power, accuracy, and sheer technology of this top "Powered Box" SVS is really quite unusual. Just one of our proprietary woofers would out-gun many high-end subwoofers' performance with ease. But with two of the second generation TV-12, "Ultra" drivers? With 1,000 watts RMS of digital hybrid BASH power behind them?? With Parametric Equalizer features built in, and our famous three position variable extension??? Forget about it, nothing else comes close. This sub isn't "at the top of its class"... it is the class.
Feel free to compare this SVS to $5,000 subwoofers you have lusted over for years. Then rest easy knowing the new PB12-Ultra/2 will blow them all into the weeds (in a subtle, deeply accurate and "musical" sort of way naturally). So, the "how much"?
Now priced at a reasonable $2,299 in rich piano gloss black... just $2,199 in furniture-grade wood... or a staggering $1,999 with fine textured black. Just jump to the "buy it now" link for the finish of your choice. Have a friend, a fit and strong friend, standing by on delivery day. While incredibly well crafted, the PB12-Ultra/2 will require some muscle to move into place.
We've long been known for loading world-class components into affordable subwoofers, but this time we pulled out all the stops. The woofer below is arguably one of the best, if not THE best 12" in the world.
Made exclusively for us by famed driver house "TC-Sounds", there are quite a few subs priced $4,000 or more with a single driver that's not even as good. And we pack in two? If you have followed SVS for some time you know that's just business as usual.
Using other tried and true components like three of our massive 4" patented port flare assemblies, coupled with hand-finished hardwood construction on the cabinet, |

and a famed BASH amp with 1,000 watts RMS flowing to the woofers... well you know we held nothing back. That the PB12-Ultra/2 can be delivered with the below features for just under $2,000 in basic black and $2,200 in stunning woods is pretty amazing, even for us. [more]

Select yours at the time of purchase and we'll have one on the way quickly.
1000 Watt RMS Built-In BASH Amplifier
  Yet another high output full-featured digital switching amp born out of the partnership between SVS and Indigo Manufacturing, one of the most capable and largest original equipment manufacturers in the world. Built in Canada to exacting standards seldom seen in this price class, its rugged, clean layout and construction serves as a perfect complement to SVS Powered Boxes. Quite literally, thousands of man-hours are expended dialing in performance that perfectly matches the PB12-Ultra/2 woofers and its enclosure. As always, we even made sure our own logo graced this amp as a reminder that no other subwoofer manufacturer has it. And since you can only get one on your SVS, you won't see them floating around the various "do it yourself" e-tailers either. Isn't it nice to know your amp was made just for your sub?
Don't let the conservative real-world power rating deceive you. Given our latest US-made drivers and the exceptionally efficient SVS box designs, the SVS PB12-Ultra/2 can embarrass other subwoofers touting many thousands of watts.

More on BASH
BASH® is a proven class of amplification, answering the market needs for efficiency without compromising sound quality. BASH® is a patented "High Efficiency Linear Amplifier" circuit topology that has taken the best of Class D and Class AB and created a new Class of its own. By combining a fast response power converter with a linear amplifier, BASH® is able to maintain both class AB sonic performance and class D efficiency.
BASH® can produce high power levels without cost penalties typically associated with conventi onal amplifier designs. A linear amplifier rated at 100 Watts should be able to deliver 20 Watts continuously. If the same amplifier is to play musical transients that are 10dB louder than its rated power, the amplifier must be able to deliver 1000 watts dynamically. To deliver such dynamic power would require the internal power supply rails to be 300% higher, and the resulting power dissipated at 20 watts output to be 350% higher resulting in increases to heat sinks, power transformer, bulk capacitors, output devices and ultimately increases the cost.
BASH® provides customers new solutions, opens new markets, offers greater flexibility, and ultimately reduces the cost of amplification.

Flush-mount Amp Configuration
What makes the PB12-Ultra/2 so unique? Well, besides the fact it’s packed with components normally only found in subs costing thousands, is that SVS sweats little details like mounting its amp flush, safe and secure in one of the nicest looking and best built box subwoofer in the world. Could we have slapped the amp, surface mounted into a square edged vinyl wrapped (or faux wood finish) box made for a few dollars?? Yes, we could have. All the advantages of a subwoofer box, with the convenience of an “all in one”, built-in amp. That’s the PB12-Ultra/2…proudly assembled in our Ohio factory with the best quality domestic and imported components , and only available at SV Subwoofers.
Integrated Base Plate with Down-firing Woofer and Floor Mounts
No matter how your rock rolls, or how low your organ goes, the shockwaves emanating from that high efficiency woofer propagate out from a fixed platform, our integrated base-plate. Not the floor, and not your ceiling. When you're in the midst of your favorite action movie scene you might wonder if such a stylish, modern looking enclosure can can really move your home theater (without moving around itself). Fortunately for SVS customers, all the drama will be on screen, and all around you in gut pounding, accurate bass. Your subwoofer will serenely be belting it out at all the right moments. Rock solid. Utterly unflappable. Once again, form follows function at SVS.
Want another example of thinking different? How about something simple, like putting our drivers in the preferred downward firing position. Easier said than done when slapping a grill is the typical low-cost solution! But doing it this way makes for the most stable enclosure. Its low center of gravity and an inherently well-protected woofer mean years of rock-solid performance. Bass that goes this low, starts there too.
So maybe you have a hard floor and it's time to setup your sub? You won't find hard plastic feet that might vibrate on your SV Subwoofer. Instead the default mounting configuration is a set of compliant foam disks perfectly suited for wood, vinyl or tile flooring. Because our subs have such a low center of gravity the same setup works just as well on thickly padded and carpeted floors too.
Precision Tuned High-Flow Port
Computer-designed and Patented, these high-flow, low noise ports are made in the USA and an industry standard. Why fix what ain't broke?? (But we do get them at a great price on your behalf...it helps when you are on a first name basis with the inventor!). 4" of free flowing internal space, and nearly 7" at their outer flare, these costly parts can breathe nearly as well as 6" straight ports. But just to be sure those killer woofers aren't constrained in any way, we pack THREE of them into the PB12-Ultra/2.
Multiple extension design 
Multiple extension modes allow you the customer to experiment with "lower than low" bass at their leisure. As it is, the PB12-Ultra/2 is configured stock to 25Hz (with all three ports firing), which will yield strong response to under 20Hz with mid-sized rooms and corner placement. Above this point is where most music and movie bass is centered. It also is the most efficient mode for the PB12-Ultra/2; with plaster shattering sound pressure level capacity, and incredible accuracy to the source material at all sound pressure levels, low or loud. Want deeper? If you willing to give up a few decibels above 25Hz (and the PB12-Ultra/2 has "headroom galore"), then insert one, or even two port plugs, click over the subsonic filter knob to the corresponding 20Hz or 16Hz position and you are there. Most users would experience strong output to around 15Hz with good placement in a typical room with a 20Hz setup and has proven very popular with the similarly configured PB12-Plus/2. This is the sort of bass that is just plain scary when done with low distortion. but it's one of the reasons SVS's are so famous! Whereas the PB12-Plus/2 will be more than enough capacity for many customers, the PB12-Ultra/2 brings a respectable improvement in total output for those that want it. Room size and shape will largely determine how much. Of course for those desirous of impeccable natural wood finishes the Ultra will be worth the price of admission even without more performance.
Hand-finished hardwood construction
Thousands of hours go into optimizing the materials, finish, bracing, and layout of every SVS, box or cylinder. Using state of the art computer assisted design (CAD) and our relentless regimen of simulations and extensive real-world measurements, no other manufacturer makes a more robust and acoustically inert enclosure than SVS. Using a 1" medium density fiberboard (MDF) core with extremely high grade clear real wood veneers, or high-tech black finishes, meticulously rounded edges, our PB12-Ultra/2 panels are meticulously machined using by hand or computer numerical controlled (CNC) tooling developed for high end cabinetry. Hand assembled, and finished with a multi-step process that's an SVS secret. With one of four stunning wood finishes (plus either piano gloss or fine textured black) this is as much fine furniture for your home theater or music room as it is a subwoofer!
Response Curve
* Smoothed, quasi-anechoic frequency response: Measured with high resolution instrumentation via "ground plane" technique, outdoors, at two meters' distance, a minimum of 70 feet from reflective boundaries. 25Hz (native) and 20Hz response indicated.
Note: In-room extension, with corner placement, will typically yield 3-5Hz greater linear extension than shown. Results will vary based on room size, seat distance from your SVS sub, and subwoofer location in the room. Chart does not depict maximum output of this model and is not directly comparable to other SVS models except for frequency response. |
