Box Subwoofer PB12-Plus Series

Not quite sure where your sub's parts come from?  How about a small factory in rural Ohio?  The new PB12-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 and a protective front grill that's just plain cool, 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" subwoofer 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, you have your hands full. 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 solid year of developmental work and experimentation with emerging materials and design, all put through a gauntlet of extreme testing in our R/D labs.  

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?

525 Watt RMS Built-In BASH Amplifier

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. Again, untold man-hours were expended dialing in performance that perfectly matches the new PB12-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 US-made drivers and the exceptionally efficient SVS box designs, the SVS PB12-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.

Front firing port/woofer baffle orientation

The shockwaves emanating from that high efficiency woofer propagate in perfect synch with our team's tuned ports. 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 an acoustical alignment that takes advantage of a whopping 1.5" front baffle and stout internal braces all cut with computer controlled precision.  Building cabinets this way makes for a supremely solid and stable enclosure. Its low center of gravity and an well-protected woofer mean years of rock-solid performance.

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 synthetic rubber cone feet, precision threaded into steel inserts, all removable of course. Because our subs have such a low center of gravity the same setup works just as well on thickly padded and carpeted floors or tile, wood or stone, without missing a beat.

Proprietary 3" high flow inner and outer port flaring

 Previous generations of SVS subs used effective but rather more common plastic fittings which required surface mounted screws and finicky foam seals. No longer. This generation of Powered Box and Cylinder subwoofers utilize costly proprietary injection molded port flares which look better, neatly integrating with the surrounding baffle with screwless seals which allow even more compact alignment than before. Computer-designed and made exclusively for SVS, these high-flow, low-noise ports are matched internally with American made flares which complement the free-flowing 3" internal diameter high-temp ABS vent tubing. Again, we don't just put audio eye-candy where customers can marvel over their elegant fit and finish. But rather, inside too where few will ever see. Form is always dictated by function at SVS. Whether you ever see it or not, we just can't hold back content when performance is at stake. Call us detail oriented" if you wish. These are quality touches you can hear, and feel.

Variable tuning design with new sealed mode

Multiple ways to configure your extension (how deep a sub goes) means you can experiment with "lower than low" bass at your leisure, and in seconds.  In stock mode the new PB12-Plus is set to 20Hz  (with all three ports firing),  which will yield strong response to under 15Hz in mid-sized rooms and corner placement.  Above this point is where 99% of all music and movie bass is centered.  It also is the most efficient mode for the PB12-Plus, with amazing sound pressure level capacity, and incredible accuracy to the source material at all sound pressure levels, low or loud.  Higher output 25hz mode is still there for max output for head-bangers in the audience. But if you want deeper? Then insert one of the included computer cut foam plugs, click over the subsonic filter knob to the corresponding 15Hz mode, and you are there, pushing spine-tingling subsonic bass to 10hz if not below.   This is the sort of bass that is just plain scary when done with low distortion and authoritative half-kilowatt power reserves.  And with the new PB12-Plus there's the first use of a true sealed mode too, for optimal roll off characteristics which many bass purists demand. SVS builds right-priced world-class subs to serve many masters. You.

Hand-finished hybrid veneer and low gloss polymer accents

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 (1.5" on the front baffle) with extremely high grade clear real wood veneers, and rounded edges, our new PB12-Plus panels are meticulously machined  with procedures reserved for the best high end cabinetry.   Hand assembled, and finished with a multi-step process that's an SVS secret.  With one of two stunning wood finishes, or always alluring piano gloss black, this is as much fine furniture for your home theater or music room as it is a subwoofer! 

Colors to fit nearly any decor

Oak

Gloss Black

Rosewood

Most companies give you few, if any choices on colors for your subwoofers.  With the PB12-Plus we give you four stunningly beautiful natural wood finishes done on clear hardwood, plus immaculate "piano gloss" or fine textured black.  Select yours at the time of purchase and we'll have one on the way quickly.  Digital monitors and imagery can vary.

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. 20 and 16Hz response indicated.

Note: Tuned for mid-sized rooms. 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.
