i was wondering how these 2 subs stacked up against each other so i emailed svs and thought i'd share the results

here's the email i got back them them (i also asked about stacking the PB):


Hi OTK:

The PB13U comes with six screw-in elastomer (grippy rubber) feet which won't damage the subwoofer finish, provided you are reasonably careful when you stack the second subwoofer. With the weight of this subwoofer, and the six grippy feet, the chances of the top subwoofer "shaking off" are virtually zilch.

The PB13U has more internal enclosure volume and also has a deeper tuning point. As such, it a slightly stronger overall performer, and has a few Hz deeper extension and more clean output capability at the very deepest frequencies. With that said, many customers highly value the much smaller footprint and lighter weight of the PCU, and are willing to accept a bit less performance for these advantages. Both subs are world-class performers, regardless of their differences, much like the standard 'vette and the Z06. :^)

The zo6 will destroy a standard vette, I don't like that comparison. I am sure people will be happy with either.

I agree....the Z06 is a monster compared to its brother the regular vette!

man, that new e92 M3 looks like a Killer!!!

I want one!!! :(

nice hijack..

The M3 has always been one of my favorite cars.


Back to the topic here is what I know.....well heard.

The PB Ultra will go a little deeper with a little more "umph"....it will also be a BIG BOX that will clearly take 2 people to move.

The PC Ultra will play every bit as good from 20hz up as the PB-Ultra....but will lose out when things drop below 20hz.....it will be a 1 person mover that has a lot of placement options because of its 16inch diameter footprint..

It really is a tough choice....you have to give something to get something....size and moveability vs depth and "umph"r....

But granted the Depth and "umph" difference will not be NIGHT AND DAY!

I'd say that bgilly is about right, .... with some clarification needed.

You've got to hear the new Ultra in comparison to the previous version to really appreciate the step up in perfomance this new driver/amp combo brings to the table.

I have had a TV-12 PC Ultra for about 2+ years, driven it pretty hard, and always been extremely pleased. After 2+ weeks with the PC13 Ultra, the following 3 words pretty much sum up how it sounds for me:
- depth
- clean !!!
- sharp

I believe the PB13 Ultra will bring a degree more depth and output.

PB13's can't wait till my pair ships... only a week or so away

Tim I think you are right. You might have to hear it to believe it. Words are one thing, but the best judge is always our own ears!

I toiled over this for a bit. Forget about about the tiny shift in the FR... I wanted a a PB soley so I could watch the front-firing driver work its magic! The problem was the box would not quite fit where I wanted it. I love the way my set-up sounds with the sub under the screen. Even on its side the sub would have been just a few inches too tall.

Instead, I (again) went with a cylinder on its side. I've had it this way for a few years with my old Ultra and it sounds great with the new one.

The tiny bit of shift in the FR will not be noticable, except in bench-racing or in areas where you are running both subs to their limits. In the old days you could save on shipping going PC versus PB, but the PC had a 119lbs UPS sticker on it... not much to save after that. (By the way, way back in April of 2002 I got a 25-31 PCi... and paid $30 for shipping!)

Can't wait to here some feedback...They were to ship last week in the Rosenut and oak. Next week for all the rest.

And from what we have heard about the PC the LIMIT of these subs is pretty darn impressive and most people probably won't touch it....

Unless they are crazy like some of us!!! :D:eek:

Actually I think a better comparison would have been the PB13U and the PCU are both like the new (Blue Devil/SS/Z07) Corvette. Nothing is better for the money!

The zo6 will destroy a standard vette, I don't like that comparison. I am sure people will be happy with either.

Maybe the analogy was imperfect (as many are), but the '08 Vette with the optional exhaust, 436 HP, improved steering and shifter, and Z51 suspension runs 0-60 in just over 4 seconds, the 1320 in 12.5@115, and has a top speed of 190. It's nipping at the heels of the Z06 in most respects and both are amazing performers - that's the message I wanted to send with that analogy. :cool:

I agree, but in car terms and pure racing the difference between 12.5 vs 11.7 in 1/4 mile times is big. I think that a comparison between the 07 vette and the 08 vette like you described would be closer. Anyway, I would get either(cars or subs), you can't lose.

Sure, the 07 vs. 08 is a good analogy. :)

You're right, most people don't realize that 0.7 seconds at these traps speeds (115-120 MPH) translates into a fairly sizeable gap between the two vehicles - roughly 120 feet.

I am hearing great things from people who have received the subs so congrats. I think someone with a smaller room would get the PC and a bigger room the PB, unless they just needed a nice finish.

Right - that's the general idea. Not that the PCU can't work in a larger room (it can and does), but the 16" diameter footprint is very attractive for customers in smaller rooms where floor space is at a premium and high performance bass is still desired.

In larger rooms where floor space is generous, then the box becomes a more attractive (albeit larger and heavier) alternative, with the option of real wood veneers and gloss black.

Or in the horse racing world, everyone knows that Secretariat holds the all time record for the fastest Kentucky Derby ever ran in the 1973 race, but what many don't know is that the horse that finished second to Secretariat that day, Sham, holds the record for the second fastest Kentucky Derby time ever ran, only approximately 2/5 of a second off of Secretariat's pace, but yet that still translated into 2 lengths behind Secretariat at the finish line.

Of course, they were only running at about 50 MPH as they crossed the finish line though (as compared to 115-120). :p

Is it just me or does the PB13 have a more linear response than the PC13? Looking at the two graphs on SVS's site, it seems that is the case. Just another note to "ponder".

Just wondering if anybody has anything else to add. I'm considering replacing my 20-39PC+ with a new Ultra. The PC Ultra could go right where the 20-39PC+ has been, but I could also squeeze in a PB13, but it would be a tight fit in my room.

On AVtalk a reviewer is saying that the PBUltra is superior to the older PCUltra. He says it's deeper and more musical. He has both at the same time.
The old PC Ultra > PC+ > PCi

What exactly are we missing as we go down this list?
Supposedly Craig claims that the PCi has better musical characteristics than the PC+ series.
It appears that even at below reference levels like say 95 DB, that people are still hearing differences.
Sure is confusing when there's no agreement on anything.

nice hijack..

That is an awfully big box for 4 17" woofers!!!!! :confused:

Man my home theater would need to be a four car garage just to fit my sub and some furniture.........:D
