PC12-Plus features and components

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 exclusive machined wood dowels are used to offset our signature baseplate, an enhancement borrowed from its bigger brother, the PC13-Ultra. The famous SVS Powered Cylinder form factor bulked up in several areas to handle the extreme power and ensure similarly extreme accuracy and durability.

Keeping our mammoth woofers down low is 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. 

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.

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 flares are an SVS exclusive and inspired by the parts done for our Ultra subs. An impressively sculpted 3" inner diameter, these have easy-breathing ports both inside and out. .

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. How they work when coupled with our premium woofers is something all our customers appreciate immediately, our of the box and years down the road. 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". Get the true sealed sub sound some purists crave by picking that customized amp setting, and dropping in all three plugs. 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.

525 Watt RMS Built-In BASH Amplifier

Yet another high output full-featured digital switching amp born our of the partnership between SVS and Sonavox  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 Cylinders. Again, untold man-hours were expended dialing in performance that perfectly matches the new PC12-Plus 12.4 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" 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 Ohio-built drivers and the exceptionally efficient vented designs, the SVS PC12-Plus can embarrass other subwoofers touting many thousands of watts.

Variable crossover (with bypass), defeat-able auto-on, variable phase, variable subsonic, Parametric EQ, high-level and low-level inputs, detachable power cord,  and LOADS of power!  This is one amp you can count on to provide years of accurate, deep and powerful bass.  Get the BASH advantage on your SVS now.

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 PC12-NSD and PC12-Plus and new PC13-Ultra subwoofers…only available at SVS.

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.
