PC12-Plus features and components -- continued.

Not quite sure where your sub's parts come from? How about a small factory in rural Ohio? The new PC12-Plus is another example of a component set we're quite proud to highlight in detail. If a sub's brain is the amplifier, then the heart must be the woofer. The fourth generation Plus woofer (which we call the Plus 12.4) again runs counter to virtually every trend in the industry: It's made by us, it's made by hand in our Ohio factory, and we released it when we were good and ready, knowing full well that its predecessor was already unmatched in this price class. It rivals its more expensive Ultra brother, taking the Plus legacy and upping the ante in every performance aspect a bit more.

But a world-class woofer is only part of the picture. Using other high performance parts like our new proprietary 3" port flare assemblies, painstakingly refined amp, and an elegant protective top grill, buying something else just got harder.

Wonder why most audio brands don't bother to show off the parts in their subwoofers?

SVS "Plus 12.4" driver: The legend continues, with the heart of any sub

When you start out to better a design as good as the third generation SVS Plus woofer (still the heart of our overachieving SB12-Plus micro-sub), you have your work cut out. Rivaling drivers from the most expensive boutique brands in the world it's compact, impeccably assembled by hand in our own factory and sports durability and innovations even the vaunted Plus drivers of old never managed. Our top designers spent a year of developmental work and experimentation with emerging materials and design, all put through a gauntlet of extreme testing in our R/D labs. We don't like your sub to ever break.

Check out touches like the one piece surround/gasket, sewn cone seams and aerospace adhesives (well, that's a bit tough to see, but trust us, it's there) much of which was lifted right off the Ultra line's unmatched 13.5" wonder woofer. And again, rather than sub-contract this bread-and-butter component, all the custom design and assembly was done in-house, where production is done in small batches for quality. Innovative assembly techniques no one else uses means we can do that, yet still keep up with demand from markets spanning the globe today. In a day when whole product lines, whole brands, are routinely sent to lowest cost bidders overseas, your Plus woofer bucks the trend, again.

What sort of driver does your old subwoofer have?

• Bifilar wound, 3」 USA Aluminum Voice Coil
• Polyimide impregnated fiberglass former/bobbin
• Single, composite layered, linear roll spider
• Spider-Integrated power leads
• Nickel-plated high-tension spring terminals
• Parabolic SBR surround
• Proprietary integrated injection molded gasket/surround
• Composite pulp/fiberglass press layered cone with sublimated SVS logo
• Low carbon 1008 steel components, electrophoresis black plating
• Dual Genox 8H/Y-35 high grade ferrite magnets
• Oversized pole vent for greater cooling and low noise

Integrated Base Plate with Down-firing Woofer

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.

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.

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. And we think that logo is pretty hot too.

Frequency Response For The Real World

* Tuned for mid-sized rooms. 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. 20Hz (native) 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.
