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!

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.

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
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.
