PC-Ultra Powered Features

Not everyone "needs" a subwoofer this good, but nearly everyone we speak to simply lusts over the components that fill the SVS PC-Ultra, even before they switch it on.  More proof that people know the best when they see it. Below you see it already maybe. The business end of this new sub, with baseplate removed for viewing. This is serious hardware for serious audio lovers.

Make no mistake, while you can pay far far more, bass doesn't get much better than what comes from this subwoofer, certainly not with such a compact "foot-print".  Since we look at all manner of products  from all sorts of OEMs in our comparative research, we're quite confident in saying you can easily spend twice as much on a subwoofer, and not come even close to the depth, power or accuracy of the new PC-Ultra.  The reasons for this are simple, the heart (our Ultra-13" woofer) and the brains (the 750 watt Bash amp) are the best components we could design and build, and afford to put in a sub this, well... affordable.

Like its paired woofer, the new PC-Ultra amp was a similar exercise in the quest for performance first and foremost.  We took a very costly and perfectly adequate 500 watt RMS amp we'd developed with Indigo Manufacturing in Toronto Canada, and went and made it better by bumping up power considerably (to 750 watts) and loaded on features at the same time.  More reliable, more capable of the incredible transients, the Ultra woofer can handle, and still includes the one piece drop-in design that makes replacement (in the rare situation it should ever be needed) literally a 10 minute job with a screwdriver. The on-board Parametric Equalizer (PEQ), room compensation, and new connection options are all there for expert users fine tuning in-room frequency response.

SVS Ultra-13 High Output Subwoofer Driver

The "driver" (or "woofer") inside our subs the heart of what has made SVS so famous in the audio world. The entirely new " Ultra-13" woofer (as it's called in-house) seen here is arguably one of the finest you can own, at any price, and it's only in our new PC-Ultra and its "Powered Box " brother, the PB13-Ultra. This truly amazing driver is built exclusively by us, exclusively for you. Virtually every part was designed by our Ohio-based crew with an eye towards the best performance possible first, and count cost second. Fact is, we don't even ask the price till we're happy we've met the demanding standards we know you will demand yourself. Beautiful, incredibly durable, and with high-tech features the most tech savvy audiophile in your home will envy.

For starters, check out the stunning SVS die cast "basket" which holds the rest of our painstakingly researched parts. Also prominent are materials from the aerospace industry such as the front "cone", and superior USA made" voice-coils" deep inside. Many critical parts are invisible, yet vital to long life, not to mention the brutal yet subtle demands your movies and music will place upon this gem. Many features are innovations virtually no other brands will use even if you do spend far more, often thousands more. It's the advantage of buying factory direct -- we spare little expense when it comes to ensuring the core technology runs strong and deep today, and will humble far more expensive products on the market for many years to come.

Let us know if you have any questions, technical or simple, about our amazing Ultra-13 woofer. It's the heart of every world-class SVS Ultra sub.

Integrated Base Plate with Down-firing Woofer and Compliant Floor Mounts

No matter how your rock rolls, or how low your organ goes, the shock waves 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.  A quad set of our eExclusive machined wood dowels are used to offset our signature baseplate with this Ultra. Even internal bracing is used for the fist time to support the massive Ultra-13 woofer. The famous SVS Powered Cylinder form factor bulked up in several areas to handle the extreme power and ensure similarly extreme accuracy and durability..

Want another example of thinking outside the box? How about something simple, like putting our drivers in the preferred downward firing position. Easier said than done in a slender column oriented subwoofer. 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.  Who needs a top-heavy sub?  Get an SVS powered cylinder and forget that.

So maybe you have a hard floor and it's time to setup your sub? You won't find hard plastic feet or metal spikes that will  vibrate on your SV Subwoofer. Instead the default mounting configuration is a set of compliant 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.

Architectural-Grade. Black Fabric Exterior

Some audio enclosures and grills are made from some pretty cheap materials. At SVS we don't cut corners in an effort to increase profits. We just hand select excellent materials that we'd want (and have) in our own homes. Specially laminated and extra thick 1.5" birch baffles, and costly high-end fabrics. All still brought to you at affordable prices.

Exclusive SVS "Tri-Power" High Flow Ports

As always, ordinary ports won't do to vent the intense pressures and frequencies of our ported subwoofers. These new PC-Ultra flares are an SVS exclusive, whopping 3.5" inner diameter (ID) and still heavily flared (both inside the sub and the outer flare, too) needed to allow the massive Ultra-13 woofer to belt out music or movie audio and still keep that tiny "footprint" of the Powered Cylinder shape. You can rest assured they are costly, but just because some makers skimp by without them doesn't mean any of your SVS subwoofers ever will.

Precision machined to mount flush with high-density seals, and flanked by enhanced hand laminated black finished Baltic Birch end-caps (a whopping 1.5" thick). You will want to keep peeking under our specially damped 15" black mesh grill just to see them.

If you think these look like highly engineered bass tuning ports... you'd be right, only our new Ultra models come with them. How they work, when coupled with an SVS driver, is something Ultra customer often can't quite believe even when they hear it. Want even deeper bass?? Take just a few seconds and Insert one of the included "port blockers" (one is inserted into a port area photo below) and you have taken your subwoofer nearly 5Hz lower in "tune". Drop it another few Hz by inserting two. Great for those intent on tweaking their sound as they want it in their room.

Resonance Free, Protective Top Port Grill

No driver to damage up top there, but who needs the kids dropping their toy cars into your sub? Specially modified for total resonance damping, these stylish grills are as good looking as they are functional. Did we mention that the special damping features were added because we once detected a hint of harmonics emanating from the grill (on a special test tone)? Yes, someone did sweat the details on the performance of each component in your next sub.  We're the largest user of these grills in the entire industry.  Some OEMs have people buy their own grills. 

We can't figure that out either.

750 Watt RMS Built-In BASH Amplifier

It's an old song if you've followed SVS's rise to prominence in the audio world, but here's yet another high output full-featured digital switching amp born our 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 new PB13-Ultra woofer 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" web sites either. Isn't it nice to know your amp was made just for your sub?

Power ratings are perhaps the least reliable way to judge a subwoofer's performance in the real-world, but don't let the conservative real-world power rating deceive you. Given our latest woofers and the exceptionally efficient SVS cylinder designs, the SVS PC-Ultra can embarrass other subwoofers touting many thousands of watts (often based on "peak power" or other misleading terms).

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 conventional 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 SVS PC-type subwoofers so unique? Well, besides being packed with components normally only found in subs costing thousands more, is the fact only SVS figured out how to take a state of the art “plate amp” and mount it flush, safe and secure in the nicest looking and best built cylinder subwoofer in the world. Countless designs were tested and what finally made the cut was something so robust, so effective and so elegant that SVS simply had to build it. All the advantages of a subwoofer cylinder, with the convenience of an “all in one”, built-in amp. That’s the PCi and PC-Plus and new PC-Ultra subwoofers…only available at SVS.

Frequency Response For The Real World

Technical notes: 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. 20 and 15Hz, 10 and sealed modes indicated.

15 Hz, 10 Hz, and sealed FRs are deliberately over damped in order to provide a gentle roll-off when measured under quasi-anechoic conditions.  This increases available system headroom, and also makes better use of available "room gain" (i.e., the acoustic transfer function of the room) to achieve a flatter in-room response."

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.
