SVS 12" NSD-AL Woofer
 SVS has long built its own woofers. The NSD-AL is one of a continuous evolution back many years now. While affordable there is nothing much "off the shelf" in the nature of this woofer, the heart of any sub. Every part was selected for maximum performance and with this latest NSD rev, we've even put on the stiff, costly and oh so attractive powder-coated aluminum cone stolen from our equally famous Plus 12.3 woofer.
The logo? LASER etched. Call us suckers for slick cosmetics when we can sneak it in the build of material. See, even though it costs much more than the excellent but rather plain "poly" cone of earlier PCi subwoofers, our "cycle time" on the Ohio assembly line goes down with Aluminum.
So you get a nicer looking woofer (hidden though it might be) and we are able to satisfy world-demand on an even more efficient basis, efficiency counts more than ever today.
With the newer deeper tuned enclosure and another round of refinements from our stalwart BASH amp chassis, you can better frequency response, and know your sub is capable of an even greater pounding than ever. Yet like all SVS products, it's still supremely accurate on anything from Jazz to
Jurassic Park. Using dual spiders, an American made
voice coil and precision over-hung motor structure, the NSD woofer might not
win every beauty contest, but you'll care little about that when
you hear how it works.
- SVS designed, US-built, high-temp aluminum voice coil with Mil-spec polyimide insulation
- Double-stacked, select-grade ferrite magnet
- Dual, progressive custom spiders with integrated tinsel leads
- Heavy-gauge, deep-stamped steel basket
- High-excursion, custom NBR surround (Nitrile Buna-N Rubber)
- High-strength/low-mass aluminum powder-coated cone with LASER etched SVS logo
- Polyamide former/bobbin
for max temp tolerance
- Low-carbon 1008 steel single-piece T-Yoke and gap plate (electrophoresis finish)
- Absolute highest quality acrylic adhesives used throughout
- Extra-high efficiency, extended long throw design
325 Watt built-In BASH amplifier
 This high output full-featured digital switching amp was designed by SVS in partnership with 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 compliment to SVS Powered Cylinders. Quite literally, thousands of man-hours were expended dialing in performance that perfectly matched our NSD woofer and the rest of the PC12-NSD enclosure. 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 cylinder design, the SVS PC12-NSD can embarrass other subwoofers touting thousands of watts. The only thing as radical as this amp's performance is the mounting we designed to flush fit the amp to our custom polymer wrapped industrial strength enclosure tubing. Only the design team at SVS figured out how to do it!
Variable crossover (with bypass), defeat-able auto-on, high-level and low-level inputs, detachable power cord, continuously variable phase control 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.
 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 PC-Plus subwoofers…only available at SVS.
Integrated baseplate with downfiring woofer and compliant floor mounts
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.
Want another example of thinking outside the box? How about something simple, like putting our Powered Cylinder drivers in the downward firing position. 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 that might vibrate on your SV Subwoofer. Instead the default mounting configuration is a set of compliant disks 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 too.
 Precision-tuned, high-flow 4" port
Computer Designed and Patented, these high-flow, low noise ports are made in the USA and an industry standard. Why fix what ain' t broke?? (But we do get them at a great price on your behalf...it helps when you are on a first name basis with the inventor!).
Each is precision fit with high quality, high efficiency foam seals and those flares aren't just there where you can see them, but inside where airflow starts. Form and function run hand in hand here at SVS.
 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.
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 MDF baffles, and costly high-end fabrics. All still brought to you at affordable prices. And we think that logo is pretty hot too.
Newly tuned deep frequency response for flat and natural bass in your room
* 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.
Note: Tuned for mid-sized rooms, providing flat powerful repsonse with enhanced bandwidth uniformity. 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. This chart does not depict maximum output of this model, and is not directly comparable to other SVS models except for frequency response.
