I'll also contact Ed and see what he says.

Thanks!

I've been running a pc12 plus and a pc13 ultra for about a year now; the combination is excellent, as long as they're well calibrated.

when calibrating, one must not forget to take into account the difference in max output of each sub. so that the smaller one is not overdriven.

 

if you listen to movies at Reference Level, then i suggest you use 2 pb13 ultras. because of room size.

room placement and a good calibration will also make a good difference.

My room is not sealed with a open staircase at both ends , 9ft ceilings . Attached to kitchen and dinning room . Aproximate size I'm not at home but my guess around 20x 30 feet and again not a sealed room.. At reference it's crazy it's like getting hit in the chest with a 2x4 a and LFE you feel before you hear it . I had no problem calibrating them at all they blend perfectly . I did contact SVS and if I remember correctly they said it wouldn't be a problem . I know if they recommended not to I wouldn't of did it . But call them for sure . I remember when I asked folks on the boards most were against it and said it shouldn't be done and could be a nightmare to calibrate them . I know they were just trying to help but were they wrong ! I couldn't be happier to this day going on 4 years and its been the only gear I've never felt the need to upgrade or change . Good luck with your choice either way you'll be very happy !

I see your PC12 is version (Bash) so you would not have problem on tour, the short Bash root model output and stops ringing for a very short period of time. In this way the driver is protected from on tour.

In your PC13 will not happen this, it is a DSP and simple when you reach the maximum, it will not let you do more than you can give the subwoofer.

It looks awesome, see PB13 PB12 + on in your living room (both are very similar in size), the model still is DSP + more.

Have you tried to separate subwoofers in different areas of the room? This would get more homogeneous response at all listening points, I would sacrifice the 6db of gain that you prefer to be stacked and more homogeneous response.

A hug.

If you guys want to talk about an odd SVS setup, I've been running a PB12plus with a pair of stacked SB12nsd's in my apartment for the past year or so. tongue.gif. Running through an AS-EQ1, everything is well integrated and (for the most part) sounds great in my living area.

BTW, I really should get around to taking some pics!

LOL!

Did you place that Logitech there on the floor or did you have it stacked on top and it fell there in front of the pluses during some Dubstep? wink.gif

No no!.. you got it all wrong. That’s what happens when you put two +’s to close to each other. rolleyes.gif

rolleyes.gif Hmm I see. My stacked SBs have only been together for a year or so. Perhaps they are taking things slow and will "get together" in a couple of years. I could use a second small sub for my bedroom. biggrin.gif

Hi!

Per Ed Mullen, he recommend to turn the Volume up of the SVS subwoofer to 0dB before running the Auto Calibration Test on the receiver. Here is the problem with turning the Volume up to 0dB, my receiver is telling me that I need to turn down the Volume on my SVS subwoofer. Ed said at 0dB, the SVS subwoofer will perform the best.

What do I do next?

I suppose the only thing to do is to turn down the Volume on the SVS subwoofer but the SVS subwoofer will not sound the best though. I am using a Pioneer receiver to do the Auto Calibration Test (MCACC).

Thanks for any advice!!

I have my sub at 0db and adjust the trim with my receiver, preamp, processor OPPO 105.
post #10966 of 15623
That is a great idea but the Pioneer will not let you adjust the trim during the auto calibration. I suppose I could go back and put the volume on the subwoofer back to 0dB.

Put the sub at 0db. On the Pioneer, adjust the sub's trim to 75db with an SPL meter at the main LP. Let MCACC run. This should give you a good result.

Thanks !! I had them split front stage and it sounded good but decided to corner load them and it seemed to make the sweet spot even bigger it fills the room with excellent LFE . I'm totally happy were they are couldn't Ask for or feel the need for more . Plus at around 150 pounds each its not easy moving those suckers around . Thanks for the advice though smile.gif

The only problem is that depending on the receiver, the sub's trim may not go low enough to allow 0 dB on the sub. On my previous AVR, a Pioneer 1020, the minimum trim was -12 dB I think, and this was not enough to get 75 dB with dual Pluses set at 0 dB in my small room. So I had to compromise and reduce gain on the subs.

That being said, this may not apply to Mantaray's situation (receiver, room, subs may be different). The 0 dB setting on the sub amp is ideal but if you're in a situation similar as the one I describe, the sub likely won't ever go near its limits and the performance hit from running the amp at, say, -10 dB, will be minimal.

But if I remember correctly, Mantaray needs all the power he can get, so he should at least try it. If the Pio's trim can't go low enough, a solution is to put another piece of equipment (this could be an attenuator; I use a MiniDSP) that allows attenuating the signal a bit more.
post #10971 of 15623
Since I never look at the back of my subs (2 SB12-NSD) while they're playing, I've never noticed the red limiter light next to the green light.. But today while watching a demo scene known for insane low bass (the server room scene from Pulse), at -5dB, I looked at the back of both subs and that red limiter light was on for both.

So what exactly does that mean? Is it causing any kind of damage to the sub, or is it some sort of safety kinda like a rev limiter on some cars (cuts power when you pass the red zone without shifting..)??

Thx.

Don't worry. The limiter LED lighting up means the limiter was active during that scene, preventing any damage to your sub. Typically the limiter is very smooth and effective on SVS subs and you probably won't even hear distortion. The sub simply won't play any louder. That scene is pretty hard on the subs indeed and I heard that the Pulse DVD comes with a warning sticker because it can cause damage to A/V equipment...

If the LED simply flickers, this is perfectly normal and not a source of concern whatsoever. If the LED is continuous for, say, more than a whole second or two, then that means that you're really pushing the subs to their limits, and if you ever want to get more output, an upgrade would be required. That red LED has been called the "upgrade LED" in the past for that reason biggrin.gif (funny, there's no limiter LED on the Plus and Ultra...)

So again, don't worry, you're unlikely to damage the sub. The LED is just a reminder that your investment is protected. On top of that, the SB12 is a sealed sub so it's even harder to push the driver to excursions that could damage it.
post #10973 of 15623

Perfect, thx very much, great post.

I'll remember that upgrade LED thing.. I like it.. next time it goes off I'll show the wife the flickering red lights and tell her we got a problem and need to upgrade asap wink.gif

She knows I can get great return on selling the two SB12's, I sold a cylinder recently and she was very impressed for what I got for it vs. what I paid 6-7 years ago.. Anyways I'm not there yet.. just got those subs a few months ago.. very satisfied with them biggrin.gif

The only 'problem' with my room is that it's not sealed, two large (double door size..) openings to the rest of the house.. bass is still very tight throughout though cool.gif

Some subwoofers (such as the SVS Plus and Ultras, and the above-mentionned Hsu VTF) have port plugs that can be used in conjunction with DSP settings to change the tuning. For example the resonance frequency can be changed to 16 Hz at the cost of a lower output by blocking one port (and changing the DSP setting). They can also be used in sealed mode by blocking all ports. Having no port the SB13 cannot be tuned differently.

Neutro... I've slowly been working my way through this entire thread. I started out by reading the past six month's posts first... and as time has allowed, I've been trying to absorb the rest, starting from the beginning.

At any rate... for some time now, I've been wanting to thank you for providing the rest of us with such well-thought-out and uniquely unbiased explanations of what you've learned, in the course of your own explorations into the world of the near-subsonic.

The answer I've quoted above -- which I just read this afternoon -- has prompted me to finally do so.

Your ability to explain so many of these technicalities, in language that is clearly understandable for those of us who are trying to learn, is both rare, and quite simply invaluable. Reading your explanations is a pleasure... and I am constantly reminded by them of the late, great, quantum physicist Richard Feynman, and his similarly uncanny ability to explain, in "layman's" terms, the most abstract concepts comprised within the quantum world.

Consequently -- based to a very large extent on your posts -- about a month ago, I bought an SVS SB12-NSD (which I absolutely L-O-V-E) and will very likely be purchasing its twin, this fall.

So... thank you. And please continue to keep up the great work!

By the way guys, very interesting (if a bit heated) thread here nominally about Seaton Submersives. But it's not everyday you see Mark Seaton (of Seaton Sound), Nathan Funk (of Funk Audio), Josh Ricci (of data-bass) and Tom Vodhanel (co-founder of SVS and PowerSoundAudio) in the same thread.

Josh Ricci's post about CEA 2010 is quite interesting, and since he praises SVS, I wanted to point that out here. Here's what he had to say:
Quote:

Most of them simply will not make overtly bad noises even during CEA-2010 output testing. On the other hand a LOT of other subs are not sounding too good when driven to the max during CEA-2010. Most of them in fact. They may be still passing CEA-2010 but you can't tell this stuff from looking at the measurements. SVS have their limiter and system protections down to a science. Their measurements are always good, the distortion is held down and the data on their products is very accurate. They also make good design decisions with most of their subs that make sense for the product niche IMO. Some units I have encountered made me scratch my head and wonder whether anyone verified the final design or knew what they were doing in the first place. But despite doing nearly everything else well...because the SVS units are not the absolute loudest subs on the block anymore they seem to often get dismissed around here.

Just wanted to share the warm and fuzzy feeling to other SVS owners.

Seriously, I don't know what to say after that, other than it will certainly encourage me to continue filling that thread (and others, as I recently got hints that I should perhaps explore other areas of the subwoofer forum tongue.gif) with small essays about what I think I understand about acoustics.
