SB12-NSD – The Gold Standard In Compact
Sealed Subwoofers
Don't let the diminutive size of the SB12-NSD fool you – this fully pedigreed SVS cranks out so much tight and clean bass, you might actually start looking around the room to find the larger hidden subwoofer. Our secret? Top-shelf components, the most sophisticated DSP software and chipsets in the industry, and a relentless obsession to extract more bass performance from this size package than any other brand.


NSD-12 Driver – Best In Class Performance
SVS never stops improving the breed, and our newest NSD-12 has even better all-round performance than its predecessor. A more linear force/displacement profile, improved transient response with less 'overhang', and even wider bandwidth elevate the NSD-12 transducer to best-in-class performance. What does all this mean to the enthusiast? Bass so tight, clean and accurate you'll catch yourself toe-tapping to all your classic jazz bass riffs.

Customer Reviews:

Worked exactly like expected. I was going to get the SB-13plus but didn't because the American Cherry finish currently offered on the plus wouldn't
match my decor. Instead I grabbed two of these.

Due to their diminutive size and relative lightness, setting these up was a snap. The
"piano black" finish might not actually quite match the gorgeous luster of a true grand piano, but I like it. While reflective, it wasn't
so reflective that it causes problems when I'm running my projector with the lights off.

The bass is accurate and quick. With two subs,
I can't comment on the maximum SPL of them. To put it simply, my ears hurt too much before I can get the limiters on the subs to kick in. They're
set up in a 20x15 room that's fully open in the back to a kitchen and dining room. Not the best room for bass, but two 12's don't seem to mind. The
big plus, too, is that the bass is very even throughout the room.

I will say that running the "Mass Effect 3:Take Earth Back"
trailer through them was a giddy experience. The 3:32 minute trailer has both musical (synth) bass and monstrous (alien ships/explosions) bass in it.
It's fun when your flatware starts shaking in your kitchen. Running music through them has been enlightening. My old subwoofer sounds limp compared
to what these can do.

The only thing these really lack is power in the infrasonic frequency range. Yes, they'll make the ground shake, but
they can't massage my organs like a ported 13-15" monster can. On the bright side, though, these didn't make me want to toss my cookies. />

I received my SB12 about 2 weeks ago and have been completely blown away. I was nervous given the size of our room (20 foot ceilings) that there
wouldn't be enough output given some user reviews and comments. After 2 weeks I have no idea what people are talking about. I have the gain at about
25% and this thing is LOUD. It is also incredibly accurate. Based on everything I've read I think I prefer a "musical" sub and the SB12 fits
that to a T. I also got the piano black finish and it is beautiful. This sits in our living room and looks like a nice piece of furniture instead of
an ugly box.

This little sub blew away my expectations. I was nervous it wouldn't be big enough for my modest Ht. wow was I wrong. I have owned a 20-36cs+ in a
12x12 room and this little sub comes VERY close to its output in my new 13x17x8 room which opens into a kitchen.

Thanks for all the quick
replies from svs helping me make this decision...I was gone from subs for 6 years and now I am back in the svs family and they treat me like I never
left. Cants say enough about SVS!!

This thing may be quite diminutive in stature, but it certainly doesn't hold back. Sure it may not be the loudest sub on the planet, it is a sealed
design after all. It still gets plenty loud for most people and further it is incredibly tight, controlled, and very musical. Now, all I have to do is
get a few objects to stop vibrating when this thing hits.

The SB12-NSD has lived up to my expectations and more! After having this in my possession for a few months now, and ran it through its paces with
both music and movies, i have been absolutely thrilled with its performance in my roughly 17x15 room. It hits hard and sounds great. Perfect purchase
to complete my system. Thanks again for the recommendation to purchase this model. The glossy black finish looks great and clean like a fine grand
piano.

I've had this sub a little over a year. It arrived when promised, double-boxed in very sturdy materials. Set-up easy easy and I was able to get a
pretty good placement with minimal moving it around the room and adjusting the phase control.

My listening preferences are weighted 60-40
toward musical accuracy vs. cinematic rumbling. Accordingly, this 12-incher has surpassed my expectations. It is tight, clean and musical. It does
especially well on string bass in jazz recordings.

WAF required that I not put something huge and boxy in the living room and this
relatively compact cabinet provided a lot of placement options. The quality of craftsmanship is high -- the joints on the rounded corners are seamless
all the way around and I love the curved metal grill. I use it with Energy Veritas 2.2 speakers, which will go down to a legitimate 35 hz on their
own. But the bass from the SB-12 NSD has more detail, not to mention much more depth.

If you're chasing high decibels and SPLs, as many
sub owners are, you probably should look elsewhere. Although this sub will get loud enough and low enough to shake my den on certain DVDs, it can't
compete with much bigger ported boxes. But that's not what I was looking for.

If you want slam in your movies, very accurate, detailed bass
in your music, more than adequate power and a nice-looking cabinet that isn't the size of a small refrigerator, you can't beat this sub.

My
only quibble is that I would have liked a wood-grain finish option to better match it with my speakers. I don't mind the textured finish and it's very
durable. But I would have gladly paid more to get a black oak or ash-type finish.

Look no further this sub is incredible.

A friend of mine swears by SVS subwoofers (who has on older SVS sub). At first I was skeptical
because I've never had a chance to listen to one first. However, after reading excellent reviews on the forums and you get a 45 day trial or your
money back, why not.

This sub puts out accurate clean bass that I've never heard from a sub before. A great choice for either home
theater or music. Now I know why SVS offers a trial period because they know you are not going to send it back.

Other thoughts...fast
delivery, quality build, quality sound and would be a 1500+ sub if it was sold at a retail store. Why not buy factory direct and get more for your
money.

Great Sub, especially for the money, delivery on time, product packed with care, sound is what was promised.

I added this sub to my current SVS setup and have been thrilled ever since. It has been quoted elsewhere as the sub, that "make's your neighbors
hate you, and your friends envious." This is all true. This sub is so impressive that it even won my wife over, who is the most frugal and
anti-audophile on the planet. Even she agrees that this sub simply belongs in our home theater. Go for it, you won't regret it.

I have the SB12 Plus, and it is the best subwoofer in the universe. I researched for weeks before making my decision on which product to buy, and I
feel I could not have chosen any better. The sound is so very clean and undistorted at any volume, the unit is so well constructed, and my rosewood
model is beautiful! I could not be happier, and recommend this subwoofer to everyone who will listen. Oh, and the price was incredibly low compared
to other products -- much higher quality for a lower price.

I have wanted to own an SVS sub for nearly a decade but just didn't have the chance to build my dream home theater. In 2010, I finally got that chance
and selected this sub based on great company reputation and being the fact this was the most affordable sub. After emailing SVS, they assured me that
my smaller room volume would be very well served by this sub. They were absolutely correct and using the Audissey automatic calibration feature on my
receiver, the set up was a breeze! My SB12-NSD sits nearly hidden in the corner yet any movie with a deep bass sound track is brought to life. I have
my receiver set to "night mode" all the time but still I have to be careful to keep the volume down when my daughter is sleeping.
/>My only advice for anyone considering ANY SV Sub - make sure your HT room is well insulated from bass sound so you can get maximum enjoyment at
near-reference volumes for movies. This is also a great musical sub with tight bass and relatively compact size to fit in your main living areas.

I really don't write reviews on products, But this one really deserved it. Look no further if you are looking for a tight clean sound, no distortion
and that can keep up with the bigger ones. This is the one for you. My only regret is not getting a second one.

Incredible sub! I did a ton of research, both online at home theater forums and in person listening to some bigger name brands like Polk Audio,
Energy, JBL and even got to listen to an Elemental Design Audio sub. After considering the quality associated with SVS, the fact that fellow
audiophiles hold SVS in the highest regard and that it was started by S and V after they met on Home Theater Forum, I decided to go with the SB12-NSD
before ever listening to it.
First, it's heavy, solid, well constructed, and looks great! I could not ask for SVS to have put more quality into
this sub, it's perfected sealed subwoofer construction.
Second, frequency response is as flat as the chart they post indicates. It sounds
phenomenal in any room because of this and requires much less positional adjustment to get a great full sound. (Most subwoofers require you to place
them in very specific positions in room corners so that the less accentuated frequencies get a little geometric boost in audibility, but the SB12-NSD
absolutely does not.)
Third, this subwoofer has more detail and articulation across the range of lower frequencies than I previously thought
possible. I'm a stickler for non-boomy subwoofers and this SVS sub made my musician ears jump up and down and cheer! Amazing musicality I've never
heard in any sub before.
All around perfect sealed sub for mid-large rooms. Outperforms subs priced >$1500 easily. Great value! This or the
larger SB13-PLUS are the very high standard bars for sealed subs.
