So you fixed one sub and the other got fixed too ??? That's even weirder. Now I'm confused. But I'm really glad you got this fixed.


Apparently yes. No more flapping sounds on both subs now. That is kind of strange though. Maybe I will send Ed Mullen from SVS an email.

Lecter, did you actually hear the flapping on your sub or was the flapping only on your recording?
Done, never heard any flapping w/ my own ears, only vids captured on my phone.

In the hyghwayman's case, either the flapping sound are there but drowned by other sounds, or the flapping sounds are just an artifact of phone recording.
It's all my phones fault.

My problem with the flapping sounds are fixed or completely gone!!!

Ed Mullen from SVS helped me to solved the flapping sounds. I no longer need to turn down the Trim Level on the receiver anymore. These Pluses sounds so good now that I wanted to turn UP the Trim Level. LOL!

What a difference the Pluses sounds now!!

Do you want to know what was the issue that made the flapping sounds?
That is so cool to read your issue has been resolved, Hip Hip Hooray!!! cool.gifcool.gifbiggrin.gifcool.gifcool.gifcool.gif

That should always occur before the driver starts making unpleasant sounds. As I said before, SVS is famous for their approach to limiters. While I suppose anything is possible, I still have a hard time believing it's being breached.

Then SVS should review this problem and offer a solution to all those affected by this problem ...
It is strange that this is happening, I had a PC13 dsp (sold it because I liked more the PB12 + box format) and not toward the noise. Then on the PB12 + dsp something wrong But which?

  • I think Mantaray could clearly hear the flapping noises.
  • It could be that the sound from the rest of the setup is masking the flapping sound. I know I for one was straining to try to listen to any flapping sounds, but my ears were already ringing from the sheer output from all other speakers.
  • It could indeed be the shockwave from the drive at close range, hitting the phone mic, that causes that sound. In my case the phone was not directly in front of the driver.

Lecter, did you actually hear the flapping on your sub or was the flapping only on your recording?

Actually one is the effect of the shock wave with the microphone of the phone and another very different than I to 2 m away listening. It really sounds as if the driver hit with something in the area of the coil ...

When I step back and sledge amp volume, I can get a lot more tour and not hear any of those noises torn on the driver.

What I do not understand is why would it effect to other Plus? Because the other Plus wiring was fine or correct. For some reasons, the flapping sounds was produced on both subs. Is it because I am using the Y adapter?

So if you have the flapping sounds like mine, you may want to open up the amp and see if the wiring is connect correctly. The red and black wire.

You mean the cable connecting the amplifier sledge, or the cable that connects to the subwoofer driver? If the option I would have seguna difficult to reach with arm up inside.

The cable that connects to the Sledge amp. Here is the picture of the Sledge Amp. Look at the 2 RED circles.

Please click on the image to enlarge so you can see it better.

Now that these Pluses working properly, they don't even break a sweat at extremely high reference volume.

Thanks to Ed Mullen at SVS!!

all that did was reverse the polarity...you basically had one sub out of phase with the other and they were cancelling eachother out. I have herd subs make wierd noises before when they were out of phase, so that makes sense if your pluses are co located.

My first pb-12 plus was sent to me with the wires backwards also. My avr was telling me it was out of phase and i called svs and they said that can happen and not to worry. Then had an amp issue and when i got the new amp i noticed the wires were put in backwards. I switched them and boom my avr now said it was in phase. It seems svs might have an issue with making sure the speakers are put together right. eek.gif

Maybe it was someone new on the assembly line . I know my PB12 plus and PB13 Ultra with the bash amps going on 4 years old have been flawless knock on wood !! They get a work out at least every other day and are on or on stand by everyday .

No idea. The next two i bought (a 2nd pb-12 plus and a pb-13 ultra) both came set up right and work perfect. I love the subs biggrin.gif

Yes!!! That's it. I figured it out in my car so you beat me to it biggrin.gif

Those poor PB12s were battling each other and just working very hard to cancel each other out.

That means Lecter has another problem though isn't it? frown.gif

I guess the shockwave can create similar-sounding flapping sounds if your camera is in front and close to the woofer, so beware when taking movies of your sub.

I'll check the connection cables.

But I have the impression that my problem is different from a simple wire positions inside out.
Please, I beg you read one of my appointments with the problem I exposed. rolleyes.gif

Well, I just opened my PB12 + and effectively were poorly connected cables.




Usually SVS makes a review of their products and is signed on the serial number label on the subwoofer. My subwoofer is not inspected.



Thanks to this, my PB12 + has built-in functions PB13/PC13 models only and SB13.

And finally, put some pictures of the construction quality of the subwoofer and to make sure that the driver is properly connected to the wires.

You can see that the center bass reflex port is a bit longer than the rest, what makes me think that if I connect a port (16Hz) Is it better to plug into one of the other two ports, left or right?








I think my subwoofer was finished last minute Friday.
The technician was thinking about the cold beer and the weekend party and therefore led to a bad connection, one more dsp loaded with features and lack of final inspection.

Can you be quiet, actually my PB12 + was not connected inside the amp. This later proves to gain maximum sledge 0 and see if the problem is fixed. smile.gif

Hi Lecter, can you tell us exactly what was wrong with the cable connection? Was it simply that the black and red wires were inverted? Or was the connector loose? If it's only a polarity inversion, it seems a common issue, and I would have thought that would lead to problems only when trying to integrate dual subs (which you will have to do shortly though).

SVS subs are made in China. I guess making them transit to the US to be inspected before shipping them to Europe would add even more to the cost.

That one is funny, a second PEQ for free. The bizarre thing is that the amp correctly tells you this is a PB12-Plus though.

That is a very interesting observation and a valid question! Is the port volume really larger for the center port? Is the situation the same on PC12-Pluses and Ultra models? Which port should be plugged when using 16 Hz tune? I guess in a PB12-Plus it's easy to simply plug the center port -- it will look symmetrical and it's easy to locate. On the PC12-Plus, the ports are arranged in a circle. Which one is the longest?

Apart from reversed polarity and the bonus PEQ, it looks alright to me. Reversed polarities are relatively frequent it seems. CR had the same problem when trying to integrate his two PB13-Ultras. Because of that, I made sure playing both my Pluses together actually raised the SPL level before going further in the setup.

Why did you tell Ed Mullen at SVS to be quiet? confused.gif



Thanks for sharing those great pictures and video. You asked a good question regarding which port to plug at 16Hz Mode. I see most people plug the middle port but does it really matter which port to plug to get the best performance?

It may be a language issue; he's admitted to using a translator program, so perhaps his original message wasn't converted properly. Hopefully that's the case anyway...

eek.gif This is what is not being able to speak English like god and use google translator to communicate in this forum.
Thousand apologies and many times more than I will have to ask.

Actually I meant that the wires were placed with reversed polarity. rolleyes.gif

I believe that if one has to close a port to work on 16Hz, it will have to shut down or left or right. The longer is the port, the lower the tuning frequency (at least that's what I think).

Now I will respond to Neutro post, I will take a while and something long, but I'll clear some doubts. Well in my hands and were all models of SVS (NSD, Plus, Ultra) and teach as the Plus is the only one that has a large port. biggrin.gif

LOL!


In a way it is not really funny because for the price ($1400) people pay for these, these should have the highest quality check (QC) before shipping them out. I am surprise because the incorrect wiring did not damage the driver or the Sledge amp.

Another thing is that SVS told me that they had to open the sealed box for ANOTHER inspection before they ship these subs out. And the wiring is STILL not correct. So why did they open the sealed box for a final inspection again???

Both of my Pluses came to me with boxes opened. They only taped the center of the box. They told me they had to open them for final inspection. So I don't know what to tell you about their quality check at SVS.
post #11336 of 15588
I think what Lecter wanted to say to Ed was simply "nevermind", as in "no need to answer that", which I see could be distorted into "you can remain silent", then further into "you can be quiet", or as a request, "can you be quiet".

And this, guys, is why we'll always need human translators biggrin.gif

So is it as simple as getting a free extra PEQ, or is it a more serious issue of the wrong DSP programing being used for driver (PB12+ vs 13U)?

Good question indeed. The wrong DSP programming could certainly push the Plus driver closer to its limits. I just don't see how that can happen though with the amp identifying itself as a "PB12-Plus".

Hi.

The cables were connected reversely. Where you need to go +, was connected - and where I had to go on - I was connected +.
But even so, I'm afraid not to solved nothing. The continuous noise in some scenes of some movies, if the gain is at 0 sledge. mad.gif

In all I had of SVS subwoofers, both NSD (Bash and Sledge) and PC13-Ultra Sledge in etiqueda with the serial number, the signature of the person who reviewed and in all cases has been one "DM ".

PEQ and a few more functions that possess ultra models. All in my PB12 +. It was Friday and the technician was about to taste the first beer of the weekend. Hahaha is an ironic way of speaking, is a joke. biggrin.gif

No, not the same. My previous PC13-Ultra sledge had the same size for all ports (inserting a jack then no matter where the foam). My previous PC13 is spoiling the amp and I had to replace it, leave a picture to verify that all ports have the same length ...






Now a photo taken from Audioholics and another from another forum. Is inside the PB13-Ultra and 3 shows that the ports have the same length...

In my case, just a subwoofer. Over time will be two, but you have to wait for the gift (hopefully soon). biggrin.gif
