Bigger, much heavier, and using a more powerful Digital Signal Processor (DSP) amp than the new SB12NSD, the insanely good SB13Plus is styled to perfectly match with either the S-Series or M-Series SVS Speakers.  With more features and more amp power than we've ever offered before, it's almost certainly another industry standard.

The SB13Plus features audiophile 2nd order tuning, with power that will run flat and strong below 20hz in most rooms, with power and refinement which set new standards in this mid-sized sealed sub class.  Nothing compares really, certainly not at anything like this still reasonable price.

Brimming with state of the art features, and designed with the latest DSP controls, our new STA-1000D Sledge^TM amps provide access to all features via a simple to use LCD display.  The amp's slick intelligent feature control knob and extensive I/O jacks are neatly integrated into a whopping 1000 watt power stage.  Of course we include pro-quality XLR connections, it's virtually a new class of amp, and one that simply didn't exist until we developed it with our fabrication partner.

The hand-made SVS Plus 13 is an all new design using the basket from the famous SVS Ultra 13" subs, using a US voice-coil, precision built ferrite motor, with one piece black glass/pulp top cone.

Why step up to the SB13Plus from it's smaller, less expensive "SB" brother?  Well one look below at what's arguably the most powerful and most advanced new class of DSP-controlled, pro-grade power sub ever built ... and basically twice the power across the board over the already incredibly good SB12NSD.  Of course, it's considerably more expensive, in fact, about twice, but only a bit larger.  So if you have the need for power and the means to step up, you would be hard pressed to find a way to spend your money more wisely.

Make no mistake, you still want the big vented SVS subs for the biggest rooms.  "Space eats bass" and even SVS doesn't defy the laws of physics.  But we do bend the rules like no OEM when it comes to price, quality, design and performance (all backed up by our typically over the top" customer service).  Expect anything similar in size and price to wither under any comparison to the SB13Plus.  In fact in most moderately sized rooms this small, stout, high tech sub will provide better and more balanced performance than one of our famously large PC or PB subs.

Quality touches abound.  Start with just the front of this new sub.  The stylish new powder-coated perforated mesh is made exclusively for us to insanely high fit and finish tolerances.  Neo magnets, neoprene isolation gaskets, cast and chromed SVS badge.  Flip over the sub and look at the bottom to find our soft rubber cone threaded inserts.

Woofers are retained by precision USA high-strength steel nuts.  looks, quality, performance are evident in every part of this sub.  It's no accident.

At SVS we consistently use the best, NOT the least expensive suppliers when designing and building a new model.

Be it the swanky grill, or the incredibly new amp technology, they are all results of 3 years of tireless work with the top audio suppliers around the world, this is the quality you can hear, feel, see.  Pick up that SB13Plus grill, examine it closely, and you'll see those baffle gaskets to ensure quiet, resonance-free operation, even at high sound pressure levels.  Precision metal work like we demonstrate is rare in today's audio industry.  No less than eight rather robust magnets are thoughtfully covered with custom black rubber cups so they all look like, well, nothing at all.  Nearly as invisible as the matching neo pieces under the skin of our signature contrasting hand-laid charcoal black subwoofer central enclosure.

All this hardware is precisely hand built by SVS into this very compact mid-sized cabinet design tailor made for stacking.  With an approx. 17" cube form-factor and real wood or hand-polished gloss accent panels, this is the nuanced deep bass small sub few brands can match at twice the price.

Generously borrowing parts and technology from our Ultra sub, the look and feel of the SB13Plus will give pause to anyone poised to spend thousands of dollars more on some other brand.  Those expensive boutique subs have always been outclassed by SVS performance, but always before with "big boy" proportions.  No longer.

Right now, under direction of our US staff, cabinets, woofers, and cutting edge new amps are converging SVS's newly created Taiwan free trade zone (FTZ) assembly facility.  The first 10 pilot woofers were assembled in July at Tymphany, you might know them as the home of world-famous Vifa and Peerless brand tweeters and woofers.  The most storied brands in audio trust Tymphany to assemble their designs and SVSound is something of an unusual client, bringing our own famously "no hold barred" approach to the mainstream audio market, not behaving much differently than we did as the upstarts over 11 years ago.  With the most talented and deep design and assembly staff I've encountered in the audio world, SVS is likewise proud to provide them with some of the most challenging projects they've encountered.  Woofers that draw gasps from veteran sample team assemblers among them.

Now with state of the art audio DSP, fine tuning from our engineers have blunted the impact of physics ... this new small subwoofer is so flat, so deep and so powerful you might even question why bigger subs exist. Big subs exist for the largest spaces of course, but for more modestly sized rooms,in the USA and around the world, SVS power and performance wasn't an option. Even for those that will put our biggest subs in the smallest spaces, they can be wholly overrun with "room gain" which takes the lowest octaves of bass, and can blow them right thru your roof. DSP controlled power finely tuned by our staff using tough "CEA 2010" test standards have created something genuinely special in the world of small subs.

That “something special” is an unprecedented level of control and interaction which matches a sub's size to your space better than ever before.

While woofer production heats up at Tymphany, another SVS team is in place in Taipei, Taiwan to monitor production of our new STA-1000D Sledge™ amps.  If you follow technology you know that many of the world’s most advanced electronics still emanate from here.  BASH platforms had already  been poised to shift production to China and not to factories under our control.

Our famously over-built cabinets are The cabinets are built to our “brick house” standards with internal bracing, and for the first time American Cherry, and Black Oak veneers, joining stalwarts Natural Oak and Gloss Black.  First production samples weathered stormy shows in Malaysia, Singapore, Taipei, Europe and USA this summer, where refinements and fixes took place.  Main production started in early September with first USA shipping to customers here mid-December.

While earlier BASH platforms served SVS customers of our big vented subs well over the years, durability lagged that of our virtually bullet-proof woofers. And our new “SB” line of sealed subs simply begged for an entirely new level of sophistication on pre-amp controls, limiters, filters and control features.  Our partner on the kilowatt STA-1000D was chosen first as maker of our already legendary AS-EQ1 subwoofer EQ, the world’s most sophisticated bass equalizer still today.  In fact, they are actually far better known for providing pro-amps in hugely powerful platforms which rarely trickle down to the consumer world.  Not only that, working closely with Formosa-Audiomate we created what we believe to be the easiest to use and intuitive feature-set ever done for premium subwoofers. 

With a few minutes and with one knob you know why we call it the Intelligent Feature Controller™  or “IFC” for short. In both 1000 watt and 800 watt versions (the latter coming soon to the more efficient PC12-Plus and PB12-Plus subs) these amps simply didn't exist before we created them. Others are sure to emulate now, the hazards of being a technology leader. Just don't expect anyone to pack this kind of technology into a package you can actually afford.

Here's a list of the menu structure in the new STA1000D amp that powers the SB13-Plus. See the (above) downloadable User Manual for a more detailed discussion of each:

Why a small sealed sub?  Millions of small rooms just like yours.  The new SVS SB13-Plus represents a more intelligent way to make ultra deep bass:

If you have a big open room (and there are no shortage of homes with all-purpose “great rooms” in the US) then one of our more traditional ported box (PB) or cylinder (PC) subs are still the most appropriate choices.  Not only are they marvelously efficient, they provide gobs of deep, low distortion, high power bass, with impeccable quality and style.  So if you have lots of space, get a lot of subwoofer – and now with our Sledge™ DSP amps, the big vented cylinders and box subs are decidedly better than ever.

But if you have a small to mid-size room (like millions of us), the “right sized” SB13-Plus is a perfect choice, simply because there’s less space to fill and also because rooms this size naturally boost the low-end bass response (a phenomenon known as “room gain”).  To take advantage of this room gain, we designed the frequency response of the SB13-Plus for a very shallow roll-off profile.  So when placed in a small to mid-size room, SB13-Plus will couple with the available room gain and will typically exhibit a flat response to 10 Hz.  This is the type of subterranean bass which cannot be heard, but it can be felt as a presence in the room and it lends foundation and solidity to the sound track.      

Below is a graph of the SB13-Plus "quasi-anechoic" (purple trace) vs. "in-room" (green trace) in a 2000 ft^3 theater room.  Note how the in-room response is notably flat to 10 Hz with room gain typical of such a space:
