PC12-Plus – Extreme Performance Powered Cylinder
The original SVS subwoofer was a cylinder design, and this unique and elegant form factor has since become an iconic symbol of SVS performance heritage. With its generous enclosure size, triple high-flow ports, high-power amp, and heavy-duty woofer, the PC12-Plus has the power, headroom, and deep bass dynamics to easily handle the most demanding DVD passages at cinema playback levels in larger home theater rooms. Music is equally well-rendered – rock, jazz, pipe organ or classical – the PC12-Plus handles it all with accuracy and fidelity.


Plus-12 Woofer – Rugged and Refined
The exclusive SVS Plus-12 woofer is now in its 5th generation of refinement, and is the finest transducer available at this price point. This woofer is so overbuilt, our R&D engineers had to push it with over two-thousand watts before it even broke a sweat. And despite this ruggedness, the Plus-12 woofer delivers exceptional linearity, low-distortion, and excellent detail.

Customer Reviews:

Years ago I had a 16-46PCi subwoofer from SVS (long discontinued from what I can see). I loved it, but had to sell the beast due to a few different
reasons. After all those years in the wilderness, SVS finally finds it's way back into my living room, and in a big way. While the 16-46 was an
impressive sub, this PC12-Plus mops it off the floor.

The pros: I honestly don't know if this sub is good for my house. My old JBL did a
decent job with the tripod emergence scene from War of the Worlds, but the SVS shook the room so hard that I was actually scared. I heard bass
effects in Transformers and King Kong that were inaudible before. Through all this, the SVS never sounded like it was anywhere near breaking a sweat,
with even the heaviest bass sounding perfectly clean. The sub's ability to be tuned to one of three configurations helps this mean tube fit in to
almost any setup.

Cons: The only real big one is that the amplifier can be a bit confusing to configure. Much as I appreciate SVS's theory
behind making everything dependent on one knob, in some cases I would have preferred discreet controls. Also, there's no hiding this beast. It is
big, and it looks like it means business.

Inconclusive: I like good sound, but I'm not an audiophile, so I can't really nitpick about the
SVS in music situations. It sounds good, and I'm happy with it.

Most people that have never heard the intense subharmonic bass in modern
soundtracks are skeptical (If not downright dismissive) of such a relatively expensive purchase, especially when it's 'just a sub'. This SVS has so
far silenced two of those people, both of whom sat in awe of the massive power coming out of this tube.

I have the plus with the bash amp. I think the drivers are the same. Great sub. Very musical. The first night I had a movie on and the sub shook
and ac adapter out of the wall. If you watch a lot of blu-rays at high volume levels I would go with the ultra. I plan on upgrading soon. I'll be
keeping the plus in another room. I love SVS and their products. Customer for life.

I love the base from my PC12-Plus. It absolutely rocks the house and gives you the full movie experience. The woofer has not proven to be very
robust. I have had to replace it twice within 10 years. This second time they were very good about covering it under warranty. Replacement woofers
are not cheap. I hate to do it but I might turn the gain down to see if i can preserve the unit.

When I played the first CD on my new sub, the sound was amazing...rich and warm without being thumpy. Maybe it's the bottom-firing design and long
ports, but the sub seems to sound more natural than many others I have heard. When I played the first Blue Ray disc, the sound went to an all new
level. It was powerful and muscular, but still very natural. It's a terrific sounding sub overall, and I recommend it wholeheartedly to anyone who
wants a realistic sound for music and movies. I also like the form; mainly because it is different than the typical dorm-fridge box....although I
debated back and forth between the PC model and the PB model. I'm very happy with my decision...it looks great and sounds great. And hey...even my
wife likes it!

My PC12-Plus has been absolutely great. The sound is unbelievable and I had zero problems after two years of use. As an MIT electrical engineer,
SVS cylinders have the best sound for the buck. I refer to it as my obsidian beer keg.

I have had an earlier version of the PC plus (39 inches tall) for about 5 years and it has impressed virtually anyone who had the opportunity to hear
it. I must also mention something about the superb customer service I received. Recently we had a power surge in our house that burned out the BASH
amp. A local repair shop wanted $600 for the repair. When I went on-line and posted a message (AVS forum) whether this repair was worth it, someone
from SVS answered with a suggestion that I call them. A replacement amp was $200 for my model and an SVS tech walked me through the process of
removing the old amp and replacing it with the new. Everything worked perfectly and my cost was one third of going through a local shop. I was quite
impressed with the support I received. Thanks SVS.

This sub is an imposing unit. But if you have the physical and visual space, and want clean, true, seriously dynamic bass that will blow off your
socks, then this is it. There is no muddying mid-bass bloat. No, all that you will hear is that subterranean sound that is actually there. It
will make your movies come alive. There is a vast difference from what other manufacturers call subs.

I was looking to upgrade my home theater sound and it was suggested by many people to look at my replacing my current sub since the area it was now in
was a bit large for it's capabilities. I contacted SVS who worked with me to find a sub that not only would give me a lot of bass response but also
fit into my room well. Deep Bass response over my trusty MK sub which was a huge improvement for my home theater.

One thing nice about
this sub is it can be pushed in a corner or behind something but remember this sub is tall compared to box subs so keep that in mind.

First of all the customer service from SVS is outstanding. It took a week for an international delivery which is excellent. This sub is just amazing
and equally suited to music and home theatre. The scene from 2012 felt as if it was happening right there. My music has never sounded better this.
This is an excellent subwoofer and can handle any you throw at it. This is well worth the price.

picked up a used plus for system ,i have had it for 3 days its very very good, i just picked up a new pc12nsd also for same room, i find the plus has
a little more depth and the gain setting is at 10am were the nsd is at 12 when calibrated. both together are amazing, i played 1 then the other and
would say the plus is just a bit better the nsd is very close .on movies they both move lots of air and go very deep, music i like the nsd a bit
better seemed smoother not sure why. but at end of day the 2 together are a perfect match in the room, both great subs no matter which 1 you get
