SVS Ultra-13 High Output Subwoofer Driver

The "driver" (or "woofer") inside our subs is the heart of what has made SVS so famous in the audio world. The entirely new " Ultra-13" (as it's called in-house) seen here is arguably one of the finest you can own, at any price, and its only in our PB13-Ultra and its "Powered Cylinder" brother, the new PC-Ultra. This truly amazing woofer 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. We don't even ask the price till we're happy we've met the demanding standards we know you will demand yourself. Beautiful, bullet-proof, 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.

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" websites 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 box designs, the SVS PB13-Ultra can embarrass other subwoofers touting many thousands of watts (often based on "peak power" or other misleading terms). You can rely on our powerhouse Canadian built amps to provide the foundation for that amazing Ultra-13 woofer profiled above.

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 and Attention to Details

Details which even the most demanding customer might not notice are the sort of thing that makes an SVS subwoofer such as the PB13-Ultra so unique. Besides the fact your sub is packed with components normally only found in competitive products costing thousands more, are little things, like mounting its amp flush and secure in one of the nicest looking and best built "enclosures" in the world.  We use domestic components wherever possible and never accept less than furniture-grade materials for your home.  The PB13-Ultra…proudly built in our own US factory with the best quality components, and only available at SVS the Sound Authority.

More examples of thoughtful and unexpected features? Maybe you have a hard floor and it's time to setup your sub. You won't find hard plastic feet which would vibrate when you are playing hard. Instead we've adapted compliant elastomer cone "feet" which are 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.

Could we have slapped the amp, surface mounted  into a square edged vinyl wrapped (or faux wood finish) box made for a few dollars? Or perhaps used hard plastics, or failed to recess components for a perfect fit? Yes, we could have, but that's just not the SVS way.  We think you deserve better than "good enough" fit and finish.

Hand-finished hardwood construction

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 subwoofer enclosure than SVS.  Using a 1" medium density fiberboard (MDF) core with extremely high grade clear real wood veneers or high-tech, high-fashion black finishes, these subs make a statement before you even switch them on. Carefully rounded edges, invisible seams, hidden threaded metal fasteners are all standard fare for us. Our PB13-Ultra cabinet panels are meticulously assembled by experienced craftspeople as they would any fine furniture.   Hand built, and finished with a multi-step process that's sure to catch your eye each time you walk in the room.  With one of four stunning finishes this is as much art for your home theater or music room as it is a subwoofer! 

Colors to fit nearly any decor

Some companies give you few, if any choices on colors for your subwoofers.  With the PB13-Ultra we give you two stunningly beautiful imported natural wood finishes, plus immaculate "piano gloss", or tough and practical beauty in our industry-leading USA made fine textured black.  Select yours at the time of purchase and we'll have one on the way quickly. 

Front firing woofer with stylish removable grill

No matter how your rock rolls, or how low your organ goes, the shockwave's emanating from that high efficiency woofer propagate out from the front of the PB13-Ultra. Whether you prefer the "grill-less" for no-holds-barred "look at me" styling, or drop on the alluring custom black accent protective grill. Just because a subwoofer might be large (for maximum performance as this one is), doesn't mean it can't fit in with your decor.

And we don't make you mess with fussy plastic fasteners prone to breaking or ruining the look of our cabinets. Hidden under the surface of our finishes are small but powerful magnets that match with precisely located pairs in our grills so that the sub looks great in either configuration, with no visible means of retention at all. It might seem like magic the first time you put yours on, or take it off. But folks in the know have come to expect this sort of thing from SVS.

Precision Tuned High-Flow Port

Computer-designed, the new SVS 3.5" ports are stylish, have no visible screws the detract from the elegant curves of this simple but critical component. This new subwoofer needed something this special to fine-tune its performance. The high-flow, low noise ports are made exclusively for SVS, and update an industry standard found on our other products (the standard 3" flares). Inside our cabinets we actually bend the port tubing so you get incredible deep and clean bass, but without a larger cabinet or unsightly added parts. Our CURVE vent system is just one of many hidden aspects of our cutting edge design which might never see the light of day in your home. Yet, not including expensive parts like this simply isn't an option if you want to wring out every bit of performance for the customer. Built to accept the foam port plugs we include with each PB13-Ultra of course. Not one, or two, we slip in three of these into the large PB13-Ultra, and inside are the same sort of flares, helping your sub flow the air needed to make the famous SVS sound.  

Multiple extension design

Multiple depth or "extension" options allow you to easily create "lower than low" bass in seconds, with just a flip of a switch and use of specially designed foam plugs which are included with each sub.  As it is, the PB13-Ultra is configured to run exceptionally strong down to 20Hz and even lower (with all three ports firing). This is already far deeper than most subwoofers on the market, and since typical rooms will "gain" deep bass in this region, the standard "out of box setting" will provide strong response to around 15Hz with the preferred corner placement. This is extreme bass. Clean and powerful audio this deep is already exceptional and verges on the point of "subsonic" sound (which is that point where the ear is less an influence on your senses, yet you can still "feel" the bass). Above this point is where nearly all music and movie bass is centered, no matter if you are watching DVD's or listening to CD's or other forms of music.  It also is the most efficient mode for the PB13-Ultra, with amazing "sound pressure level" capacity, and incredible accuracy to the source material at all sound pressure levels, low or loud, even in larger rooms. 

Want deeper still?  If you are willing to give up a few decibels in SPL capacity above 20Hz (and the PB13-Ultra has more "headroom" than most folks will use), then insert one, or even two port plugs, click over the subsonic filter knob to the corresponding 15Hz or 10Hz position and you are ready to move your home.  Most users would experience strong output to around 15Hz with good placement in a typical room with a 20Hz setup.   This is the sort of sound that's literally frightening when done with clean power and low distortion. 

Response Curve

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.
