Looking for a single sub or a pair of 12s to blow away my CVRS

[thevic24 5,000+ posts]

thats not my reasoning, you guys just aren't giving the cvr the respect that it deserves thats all. I heard cvr 15's in a sealed box and they played almost as low as my SI mag's in a sealed box. Also my 15 inch Si mag's played lower in a 5.2 cf sealed box(smaller than recommended) than my 15 inch Si mag's in a ported box tuned to 30 hz and 7cf. Just showing you guys that sealed generally plays lower than ported boxes. Also if that is your logic, why wouldn't you help the OP design a better box for his subs cause i do agree that install is everything and a box can make or break a subwoofers performance, but since the OP doesn't have room for two 15 ported i can see why some may suggest one 15 ported but that doesn't mean it will get louder and lower than what he has now and thats my point. I do agree the aq is a better built sub for overall spl but its still all in the install.

Iam not trying to start a pissing match but if you have been in car audio for 25 years your above statement is not helping you.

Using your own example with winsid, every single sealed box that I model for a given woofer has a much higher roll off vs the same sub ported.

With that also, the ported boxes are much louder(spl) in a ported box vs the sealed box with a given power at any given fq.

Here is what it comes up with...

This is ported

This is sealed

So using your own logic you just contradicted your self. As you can see from the examples above, the ported box digs much deeper and

will be quite a bit louder.

And yes, I DO have experience with just about every Kicker sub there has been as well as owning the vcr 15, 12 and 10" as well as having and using

the DD 2500, 3500, 9500 and the AQ's as well.

In most cases, you will gain more output going from 2 subs sealed to one ported.(given the same power, and not going from 15's to 10's, 8's so on..) The gain from going sealed to ported is usually a larger gain vs adding a 2nd sub with the same given power.

As far as giving respect to the CVR's, thats fine and they are an ok sub for a "entry level" style sub. Iam sorry but they just are not in the same league as the AQ's or the DD's. In the OP's application and with my own FIRST HAND experience with both subs, yes a single AQhd3c12 or DD3500 ported should be louder and get lower vs the 2 sealed CVR's(as long as the box us built correctly)

Like I said, Iam not trying to be an *** but I do have experience and have owned or own the above mentioned subs so I do have an honest opinion in the matter. The CVR's are an ok sub for the beginner looking to get into the game but they are just not that great.

sorry but i go with real world experience not winsid. Like i mentioned i have two 15 inch mag's and i had them sealed and ported, same vehicle same amp, just a box swap and the sealed box played lower, it went down to 15 hz and flexed my truck without hearing anything. As you can see from your graph that the sealed box plays louder down low(15 hz) and thats what i said. I didn't ever once say the a sealed box plays louder lower, i said it plays lower. Either way, sorry OP for jacking your thread.

why does it matter if the subs will play at 15hz. honestly, how many songs that you listen to on a daily basis have 15hz notes longer than a fraction of a second on a low drop?

for daily listening there is no reason to drop below 25, and depending on the type of music it will never get that low.

do us all a favor and use common sense

Aha it's alright, after hearing this one dubstep song on my system, I'm not sure if I need to change my subs lol, actually got pretty loud to me and sounded amazing and hits a good range of frequencies, definitely the best system I've had by far.

Sorry, I missed directed the winsid comment, it was for someone else.

Now again your are wrong about the graph. Sealed at 15hz the sub is down 14.98db where ported it is only down -9.15db. That is a 5 db difference. Now in the real world cabin gain would add to both applications with the ported box taking the win again. . With a properly designed and tuned ported box, the same sub will almost always be louder at lower fq vs the sealed box. Apparently the ported box that you tried, your sub did not like.

Hmm...

You "never one said that a sealed box plays louder lower"??

"as yo can see from your graph that the sealed box plays louder down low(15hz) and thats what I said."

So you did just say that it plays louder down low......or didn't you?

No Kangaroux you're the genius cause we all know a beefier looking sub will always play louder than one thats not as beefy, lol and Kushy_dreams my posts is not making fun of anybodys posts, wow talk about ignorant.i tell you guys what, when the op does what you say and is still not happy then you can tell him what he did wrong, i have maybe 5 posts in the thunderdome and i've been in caraudio since 1986(25 years). I'll let you smart guys with all the experience give the advice, i don't have a problem. Funny thing is my friend was in the same boat as the OP and did something like what most of you are suggesting and he wasted his money and was not happy. Sorry but i'm not here to argue but to help. OP i hope your happy with whatever decision you make, i'm out. Just curious how many of you have experience with kickers cvr's? i do. OR are yo guys doing what most kids in here do, go by hear say and offer advice without experience with said products. Like i said, whatever the OP chooses i hope your happy. No wonder most of the veterans don't come around too often, this place is all about young kids giving out advice for things they haven't experienced for themselves.

These are the same people that will tell you things like Type Rs **** because it is a mainstream brand. When in reality they have no idea that a bigger motor doesn't mean louder. In this situation the OP is not going to gain much, if anything going to two smaller subs on the same power. The box and amount of power is going to have the most affect here when trying to overcome cone area. In an average setup if he were to port those 15s and run them off the same power it would yield the best results.

I'm not picking you out, but why do you all nut hug on fs or any ts spec for that mater. The algorithm is an incomplete mathematical equation wich includes a fudge factor. Home audio in low rms situations and controlled environments fs means something. In car audio most ts specs are in no way accurate. Not to mention that how they are posted is not even the same from one company to another. When comparing subs the fs and other specs can be looked at but do not in any way think that it means anything. In reality it means one thing. The with a lower fs "may" get lower new. However over time when the other sub gets broke in and becomes able to get lower and lower. The other sub will get weaker and weaker from suspension fatigue.
