Official SVS Ultra 13 thread - Page 220

Im not taking anything away from peeps who have bought their SVS subs already. I was mearly pointing out that I had a bad experience with them. DIY is a much better way forward for me. I took alot of my inspriation from the USA with regards to DIYing which is why I built my subs.

What I don't appreciate is slander against us brits with something nothing to do with this subject. I really hate that. All I can say is if your gonna say something about us back it up first. I am one for standing up for our country.

So you are saying my subs are crap! Em! You talk mud, thats one thing. Oh and boddingtons is nats pi55.

Lets get this right. I have a behringer EP4000 running my subs 2 ohms with 1200 watts each with the two FI Q18's in 11 cu ft boxes and you are still saying that the SVS is better. What is your set up and how many subs do you have and what have you had just out of interest?


Graham

Man my ancestor William Goffe signed the order to take out Charles I.

On the way to Windsor Castle check out the plaque.
So ther was no insults only kidding.
When I was there everyone was really laid back mate.
You sure you are british?
So no insults were given only jabbing. Geesh.

not to bash America, but my plan is to move to Great Britian, buy a shire with a nice field(through a third party, damn british land ownership laws) and a crap load of sheep. Seeing the sheep everywhere was kick ass. You guys have a beautiful country, so in no way was I putting it down.
I will be bring my Ultra clean Ultra with me ofcourse, then I will bring over some pints and we will see which one rule the castle my freind.

Just one little accurate, tight, musical sub. No extra puffery(thanks pepar), just good clean low(10hz at 60db at -31 on the knob, 15 hits 70 or so, and with only 750 watts...) BASS.
So that is that you are th eking of bass. I kneel down to your greatness oh muddy one...


And Boddingtons is very popular there.

You are right sorry.

Just so you know the kitten was trying to land under the desk....

Now for a serious question. Graham got me thinking.
Has anyone tried and increased the power to the PB13's driver. Kinda like the old SVS unpowered subs of yester-year. If you took an amp like his and powered the sub, in its's same enclosure, I wonder what would happen.
And no Graham the driver will not disentergrate...

Or even take it further and drop it in another enclosure. Bigger like his.
Ours is what about 10cu ft.?

This would be an interesting project.

Our driver is a damn work of art.

You mean he wasnt trying to cross the road to get to the other side ! For a second I thought he was trying to fly

Interesting idea. I wonder which amp you could try without running the risk of overdriving the driver. Also, would a different amp improve the musical performance of the sub?

Over on the Rythmik website, there's a mention about having variable (3 setting) dampening adjustment to vary the sound to your taste. The concept had me questioning what the is thedampening on the Ultra 13 and if there is anyway to modify it to accomodate multi setting dampening.

Another consideration would have to be if there's any DSP adjusting involved to help flatten out the frequency response.

I thinking it probably would be a good idea or certainly a good test to see what you could get out of the SVS driver. The 13" ED driver looks very similar and that's had pretty good results but I think you will struggle to get any information out of SVS with regards to it parameters and whether you could buy it direct as I would have to guess you could only get one to replace the driver if it goes. I could be wrong. You never hear of anyone doing a diy sub with the ultra driver.

Why don't you see if you can buy one and let me know how you get on. If you can at least get the parameters then we can have a look at the winisd plot.



cheers

Graham

The Ultra has multiple tunings settings for different number of ports open/sealed. So if you bypass the internal amp you are bypassing the dsp that controls the enclosure-specific tuning, and probably a little internal eq to get the response right. At that point you might as well just get a stand-alone driver, build a box and pair it with an amp. The amp is designed to work specifically with the driver and enclosure.

If you're going to use the Ultra driver in a DIY application, you're wasting money on the Ultra enclosure and amp just to get that driver...

Anyone got the TS parameters of the Ultra driver to see how it would model as a diy sub.

Graham

In thought this was a suubowwofer thread

Actually for the record, more than one type is sold in every pub. Very cold fizzy beers, largers, like US beer, and Ales and stouts. Ales maybe warmer than lager but its still served below room temperature, should be around 15C. Depending on whether you are in South or the North the beer may or may not be served with a creamy head.

Graham, nice of you to defend us Brits against sterotypically phrases but actually I like Boddingtons. Its not the best, sure, but its not bad either.

Back to subs. I have a PB13U and love it. Sounds great when hooked up to my SVS EQ1.

M4rk,

As I said the PB13 ultra is the only SVS sub worth buying in my experience. I did however want more and to buy two of them would set me back nearly £3000 hence why I built my two FI subs. I had alot of chats with our FI dealer here about them and for the cost of less than one PB13 I have something with significantly more power, more low end attack and with alot less effort.

I found though that even the PB13 sounded a bit harsh especially when watching Ironman on near reference where as I can watch any film at near reference with not even them breaking a sweat. I can not take anything away from the PB13 as its a great sub but performance per pound you can't beat DIY. I could build a single 18" maelstrom tuned low for £7-800 and that on its own would be in a different league.

I think its a fair point in my opinion. Its a shame that if the Ultra driver can take much more then why not build a bigger more powerful SVS sub. Especially seeing as the yanks like their subs big. Or atleast most of them do.

I am a lager drinker but prefer alot of nice strong belgain beer!

cheers

Graham

There are good reasons that SVS doesn't design a bigger, more powerful sub than the 13 Ultra. They do not sell in sell in sufficient numbers to make it worthwhile and shipping/packaging becomes increasingly expensive and difficult. While of course there are a number of crazies on this forum in which there is no limit to the size they will endure, the overall market for giant subs is very small. Sure, there was the Epik Conquest for a while, but where is it now? How many did they really sell? I'd bet SVS sold more Ultras in a month than Conquests sold by Epik for the entire time it was available.

gperkins, you are on the outer fringe as far as to what degree of boxy unsightliness you are willing to tolerate in your room, not that there is anything wrong with that. You are also in an extreme minority as far as the problems you encountered with your PC13. You mention port chuffing at -20db level. That seems almost impossible with proper setup assuming calibration ws correct. I wonder how hot you were running your subs? You also mention hearing air running up the tubes in your Ultra even when the ports were sealed. That is not really possible since with the ports closed, there is no net air movement. There is no air moving up the tubes when the ports are closed. Also, out of all the PC13's out there in service, you were the only one to report that particular problem. Maybe you had a bad unit or you broke it by abusing it.

There has been quite a few people over here in the UK with chuffing issues. I had the SVS dealer over to my house where he heard it with his own ears. I can't remember exactly how hot if any it was but I normally run them a few db hot. The thing is I couldn't get the PB13 to chuff at all and it was run the same way as the cylinder subs. It could be a duff one but I doubt it very much.

I have no doubt they sell alot of subs as they have a great name which serves them very well and when you email them for help they are always quick to come back to you which I take my hat off to them for that.

Even the dealer over here couldn't do enough for me. I am not too sure where Epik are going as they seem to be slow in moving forward with regards to their subs. Even ED seemed to be moving much faster with where they are going by bringing out new subs all the time with nice wood finishes.

It would be interesting though to know how far you could take the ultra driver. Don't you think!

cheers

Graham

I'm sure SVS already knows exactly how far you could take that driver, but yet they don't seem to be rushing to power it with bigger amps or to surround it with radically different sized boxes. Maybe the current Ultras are already the optimal designs for that driver. The new sealed subs SVS is bringing out seem to be using different drivers.

Grant,

I think where we're getting confused is that you are talking about a column version that made the chuffing sound and the box version that didn't. Is that correct?

Were you running a single or multiples of the column version and what spl were you getting?

Not the best but very nice. I like the pint size they come in.
And for the record, I love the Brits and all things British. Where else can I eat beans with breakfast, have ma tea and dunk my clotted cream covered scones and not get picked on??? Definitely not here....

After back and forth with pepar I am considering the EQ1. Have you had it since the begining? I figured it would help with a dual setup.

I have a chance to upgrade and am thinking about another PC-13U. I have also been reading a lot about a SubMersive. Does anybody here have any first hand knowledge of how the two would compare. Dual Ultras would be wonderful but I have read nothing but positive things about the SubMersive. My room is just over 2000 cu. ft.
Do I need a second Ultra? No, but that's hardly the point is it? I've never heard any "port chuffing" so maybe I'm not playing it loud enough. Maybe I should calibrate it 10 or 12 db hot so I can see what that's all about. Isn't that how the wankers do it? j/k

I wonder if the 13.5 is at capacity?
My old PB2/PLUS had dual driver 12.1 and 900 watts for both.
I would think it definitely could take more power. That driver looks so damn mean.
I know someone who has the old unpowered SVS CS 20-39 cylinders and pushes them with a two channel Crown amp that puts out 800 watts per channel.(@ 4 ohms)
He has the gain set to 1/2 and this seems to be just right . They were originaly sold with a lower powered amp. I think it was in the 200-300 watt range or so.
So hopefully ours could take more and just laugh at it.

Graham, I think spending 1700 to get a driver would be foolish for sure. This was just an idea sparked by our very delicate back and forth.

Graham said I was the wanker....j/k
I run mine 5dbs hot with the Ludacris and such, and at very high volume. And never a cuff or huff.

Try here to help. I am of course biased toward the SVS. Just ask Graham...

From what I've read because I did nearly buy a submersive prior to going down the diy route and that the submersive loses slightly between 15 and 25hz but wins below 15hz and above 25hz. I would be very surprised if one submersive could out gun two PC13 ultra's though.

With regards to the chuffing, it was only on the PC13 ultra and the PC12 plus. Both cylinders did the same thing. But now with the PB13 ultra.

I never had the EQ1. Having spent £1350 on the sub itself I didn't have the funds to cough up another £650 for the EQ1. I basically relied on Audyssey at the time to correct things. I now do my EQing by BFD and am very pleased with the results. I think Audyssey does a pretty good job and the BFD gets me where I want to be and I can set up different sets of filters for music and movies.

My duals are co located about 15 feet apart symetrically and I get the full 6db of gain from 10hz to 30hz so I am chuffed to bits about that. I would maybe consider the Anti Mode but for my uses £650 is far too much for me to spend.

cheers

Graham

Never said that mate. Very disappointed that this kinda language is allowed on this forum. Its not on the shack, so don't use it especially as I have never said it in the first place. But now you have mentioned it, you are kind off acting like one. Oh! well.

Graham

TOO much Boddington's for sure there mate.
No this is not a subwoofer thread. This is a thread dedicated to the PB AND PC13-ULTRA. Not a I can build a cheaper, bigger, louder sub- then your premade sub....

At least that is how it reads.

I would love to be able to DIY. I have the knowledge and the experience, just not the tools and space. I do agree with English that you can make better for cheaper on your own. Especially now, with the inet and all the info that is at the tips of ones fingers.

Man you are just not nice.
I was kidding again.
But you , like my wife have a way of trying to twist something you started, into the other persons fault.
Wanker is a non offending word here in the states. More comparable to being called a wiener...

A joke is a joke. J/K is just that.
Go to a DIY thread and blabber there.

And what is this other form of EQing you speak of? I am not to happy with Auddyssey my self. And th eEQ1 is pretty pricey...

True. Tools, like a router and table saw would be my weakness. Yes DIY is great. I build all of my sub boxes for my autos myself. Carpet hides alot of, let's say, imperfections.

I am not against DIY, the Brits, or Graham. Though he is easy and fun to get a rise out of...
But again this is a SVS ultra thread....

I wonder if I go to the DIY section and started criticising , bragging and blabbing how long that would be allowed....

Not long I am sure.

It is here unfortunately in the UK hence mentioning it. I guess all countries have their different ways and sayings. Its hard sometimes to figure out what is the right thing and wrong thing to say without affending people.

The Anti Mode is only £210 and works just by pressing one button and within 5 minutes, job done. People have had good results with it.

The EQ1 is still the better EQ device but it costs.

cheers

Graham

I used to do a lot of sub boxes and other custom stuff for cars, back in the day. Now, I don't have the tools anymore and the space to make the mess that comes with it. I even entertained the idea of using an SVS woofer in a custom box....for about 2 seconds. On another note, it seems to me there was a group of people that didn't like the way the Brits did things, back in the 1700s I believe. They kicked their Brit wanker arses back across the pond! Fish and chips, Felinfoels, Abbey Road Studio and the Beatles....I'm not against the Brits either. lol
