Meh, the response for the new enclosure is somewhat similar. I figured out how my car responds with the subs in that position so i would like the response to have not much more than a db peak from 30~55. I like my response a lot better now but still could be better but i dont have the room to tune my sub any lower or make the enclosure bigger.Stop worrying about the response curve on winISD lol... You should know by know it is only a very rough guide at best. Not mention the idea behind the response curve will change as your power and wants/needs change.

I would love to do two zcon 12's on a better amp. If I could fit the box in the space I have.
Yeah i love my zcon but im not sure what i want to do for my next setup. I was thinking 2 zcon 12s or 4 xcon 10s on a crescendo 5500 but its hard to get the response i want in winisd with those, so im not sure.
Cool I have a 2009 Jeep liberty with a 12" zcon on 1500 watts rms.
Yes it is and still on the sundown 3kWhat size and type is that sub?
Is it still the 18 zcon?
It gets Very loud!
I may try the zcon 12s but im not sure yet. Im gonna have to do some modeling in winisd to see if i can get a response that i want. I think i can get the response i want with two xcon 12s but im not sure i i want to run a 5500 on them.

I feel bad for you. My wife has this car and it sucks.
Hahaha, its not all that bad. I have had a few minor issues with it. The catalytic converter went out on it but luckily ot was still under the warranty, i just change all the brakes, new tires, and new front struts all in the last 3 months. Other than that its an alright car, nit the greatest but it gets me 29 mpg even with the weight in the back.

the box is not done yet but i got tired of messing around and wanted to hear it, so i will end up finishing it later. right now it is right around ~6.5 cubes net tuned to 33~34 with two 6 inch aero ports. The ports are 4 inches away from the bottom of the enclosure, so when we get some time we are going to trim the ports down another inch and see what we can get.
we have not done much testing, but 42 hz seems to be my peak down in the kick.

my first enclosure sucked, obviously, since there was only around 4.5 cubes net with only 70 square inches of port, so i decided to finally get around to building a new enclosure.

i guess i will start posting updates on here since i have been changing a lot of it in the last year.
bought me a ZED Ra a year ago, i love this thing.

When i was little i had an "imaginary" friend but he always came and went as he pleased and it was always as if i was talking to another person and i had no control over what he said.My mom always thought it was a spirit, i didnt care because it gave me someone to play with. Once we moved i never saw him again, i tried to imagine him but no luck.

That is pretty sweet that your wifey is on happy terms with the ghost. My father passed away in the house my mother still lives in, but there have been no signs that I know of that he is still around.
In a sense, that is a good thing that there is no sign of him. What i think of as a ghost is a spirit who is somehwat stuck here and/or has not moved on.

We all know why he blew it up but your explanation is still incorrect. If you would go through the topic, from the link you posted, you would see that one person had it correct when he said "I frequently load music files in adobe audition which monitors db levels of the signal. MOST songs I have looked at reach 0db at some point, and some exceed that (clip) frequently, although the average dB level of the entire song is often -10db or less."
No, your information is incorrect. He gave the sub too much power and we all know that. For that reason its a customer abuse issue, not warranty.
Your information is incorrect.Here is some info for you guys.
Notice where he says that a -6 db tone will cause a 1000 watt amp to put out 4000 watts.
"lol a 0db test tone means it's recorded at reference level, 0 decibels
below the peak level capable of being recorded onto a cd. a -6 tone is
6db's quieter than that. If a tone at 0db's puts out 1000 watts from
the amp, a -6 tone will put out 4000. So yes, a 0db tone is louder than
a -6, so gains will be lower with a 0db for the same output. If you
set gains with a 0db tone, your gains will be very low and you wont' see
much power out of the amp on any tone other than a 0db peak on a
recording. setting at -3 or -6 means you'll get close to RMS power at
the normal parts of the song. SPL guys set gains with tones because
they are pushing things to the absolute limits and will be burping with
that exact tone. Granted I come from more of a SQ oriented mindset,
where people know how to properly use their equipment and dont' tend to
overdrive things constantly. If your that scared, use a 0db tone, just
dont' wonder why that that tone got loud but as soon as you pop in a cd,
everything is quiet. Techically anythign other than a 0db tone will
probably clip part of the time, but that also guarantees you'l never see
alot of the power from the amp either. If you don't trust your ears
and find 0db is really quiet try a -3."

Why do you think that using a -6db tone is asking the amp to produce 4x its power?
I looked at your very first post and you mentioned that you had set your gains with a scope and had no clipping. By setting your amp with a -6 db tone, you are asking your amp to produce 4x its output. By doing that, that actually does mean that you are clipping during the peaks unfortunately. I hate to say this, but you have actually over powered your sub. Your sub sould be powered with 7500 watts RMS so that way you can properly reach your peaks wthout the amps going into clipping. By using a -6 db tone, you have accually tried to give your sub 12,000 watts RMS at its highest peak while it should be powered with only 7500 watts RMS at its highest peak. What I mean is is that by setting that 3000 watt amp at -6, you tried to output 12,000 watts RMS which is too much power. You should have actually had the amp set closer to - 3 or -4 db and then the amp would have been properly set for how the sub is rated. At -3 db we should get double the output which is roughly 6000 watts RMS at its highest peak which is pretty close to the target of 7500 watts RMS. Hope this makes sense. The gain was just turned a tad too high and thats why the sub blew.it was a 50 hz test tone at -6 db if i recall..but here is the kicker. since this incident i have not changed any settings and have been running a hdc4 15 with no issues..also a dd 9515 for some time. this whole situation left a sour taste in my mouth but its what i expected..working in customer care my self, most companies dont take ownership of sitations but its the way it is. Maybe i can afford another sp4 or team fi sub one day..i do however believe this was not my fault, and if you guys are saying that there are only 6 cases of this issue, isnt it possible that out of the thousands of subs produced, it is bound to be a few that have defects?i think this sitation could have been handled better by fi, but it is what it is.
By the way, to find the max power of your sub during its peak, you want to take its RMS power which is 3000 watts and multiply that by 2.5 which is roughly how much higher a peak is compared to the non peak. By taking 3000 x 2.5 is how I got 7500 which should be the max power applied to the sub in order to fully power it.
I don't "think" that its causing the amp to put out 4x of its power, but I know for a fact that it does because 6db equals 4x. If you set a 1000 watt RMS amp at -6 db, it will try to put out 4000 watts RMS at its highest peak. Its not what I think, thats just how amps work. If you set a 1000 watt amp at -3 db it will try to put out 2000 watts. For every 3 db of increase power doubles. You start at 3000, and it goes to 6000 at 3db. At 6 db we double once again which brings 6000 to 12,000. Just how it works my friend.
Just because a song has a peak a -1 does not mean that the average or "rms" of the song is -1, it will usually be -7 to -12 usually, while the average of that -6 tone is most likely -9. It all depends on how much compression and etc... I have songs that peak higher than others but are not allowed. Anyway, go try out what shizzon posted.

True, but i like to know where my amp is set up and even if it is not perfect it gets me close to the point that i want. I like to mess with music and edit the bass lines and i know that a lot of the music i listened to would do just fine with a -10 tone so thats what i used. I didnt have any issues with the songs except for a few that happened to be louder, then i had some clipping issues but i realized it and always turned the volume down on those songs. I also ended up buying a zed ra and set the compressor up around the tones level and now i never have any issues.
There are no tools you can use to set it "dead on" either. Music dynamics, Hell even power supply dynamics are enough to never have the ability to be constantly level matched. This is the basic fundamental flaw of the dd1.
all im saying is by ear can get u close but no way it can be set dead on .People have been doing it for ever.

biggest box that will fit in my trunk without having to be built inside.
why do i need to bump up the port area if im getting 13.7 per cube??
There are also threads on here that talk about port area and there are some links to some calculators to help determine the port area you need.

I had to turn the news off. I cant watch that kind of stuff.We shut down around noon to get everyone home. After it had past through many of us (including myself and my wife) went out to help with search and rescue for several hours.
While I am glad we found and helped many, some of the things we saw will simply never go away. The horrific nature of this event and the children lost is..... well words can just not explain how I fell right now.
I am grateful that we are "ok"...but that is only physically...mentally that is a whole different story.
Took the car to the dealership for a safety recall and they had CNN on in the waiting room. I couldn't stand 5 minutes of it and had to leave; those reporters are like pucking jackals.
Yeah, i understand that they are just doing their jobs in all, but i wouldnt be able to just stand their and report, i would rather help.

I could also do what you suggested and use two ports and plug one up, which could drop the tuning to where i want for daily and still get plenty loud and i could unplug the extra port and have it tuned way higher to mess around and get numbers.
