Enclosure for door speakers?

[wof131s 10]

Am trying to find out which application would yeild the best results. I recently perchased the JL C5 comp. and was debating whether they would be more effective (Best SQ) in a small fiberglass enclosure in the door or just put them directly into the door without an enclosure. Any help would be great, thanks.

I vote fg door pods but Im probably being bias. Will the pods be sealed?

[KU40 173]

I'm not sure on those speakers specifically but generally most off-the-shelf component systems by major manufacturers work best infinite baffle. So just make sure the inner door skin is well sealed from the "chamber" inside the door. This is effectively a large sealed box.

[Impious 1,476]

Car audio drivers are typically designed to perform optimally without an enclosure.

You would have to email JL Audio and obtain the T/S parameters to determine what if any enclosure size might "improve" performance.

Yes, i was thinking about making some sealed fiberglass door pods.

I was on the phone yesterday for about a hr waiting on tech support to answer the phone to find out which would be better. Got tired and hangup, ill try again sometime next week. Just thought someone here had these comp. and would offer a suggestion. But thanks to everyone that did.

I have installed the C5's before and i believe JL recommends they be installed IB. The qts i believe, is .6 something. They recommend the door is well deadened and sealed as said before) to achieve good sound quality. Hope this helps...

Maybe try emailing them. I emailed them a couple years ago to find out the crossover points on the JL XR components and I received a fairly prompt response.

Generically speaking if you compare an arbitrary sized enclosure with IB, the IB will kill; however, as with pretty much any driver if you have an optimal enclosure size the enclosed driver will win. Granted these drivers were designed for no enclosure so I wouldn't at all recommend it. If you do acquire the T/S from JL I would still expect you will have to try at least 3 different enclosures to really get them dialed in as your car will be far from an anechoic location.

If you had bought diy drivers it would be much easier and then perhaps logical if you did everything right to use an enclosure, but considering your component choice I would highly recommend not doing it.

Classic case here of if you need to ask the question you probably don't have a deep enough understanding of what to do to pull it off effectively. And yes, through threads and support here you could but you are a long ways from that right now.

But isnt that what the forum is for, to get insight and opinions on how things are done. I get the theory here and other places, then put it into practice. If I dont have enough understanding of something and wanting to learn, then how am I going to get the know how when i get "if you need to ask the quesyion you probably dont have a deep enough understanding of what to do to pull it off effectively" from the place where the support comes from. Like we say home, experience is the grand father of learning. If you dont try, then how are you to gain understanding and experience.

Then sell those JL's and buy something we can help you build an effective enclosure for.

Let me make my comment more clear. At this point your understanding of how speakers and audio work will not develop fast enough for you to successfully ask the right questions here, get the answers you need and pull an enclosure for those JL's off successfully. If you are just into doing it to see what will happen unless you take a scientific path with it you won't learn anything from that experience either. So yes, if you need to ask if it is okay I don't think you should do it. If you really want to do an enclosure you should start with a driver that is optimized for it, but that thread would have a completely different feel to this one.

[wof131s 10]

So your saying I have to sell my chose of equipment, and buy something you know about. If thats the case then why even get involved in the thread? Like i said earlier, i thought someone on here may have the components and would offer some advice. Everyone has their chose of equipment, why should they sell it because one person says they should? Am trying to take a scientific path, thats why am here. If i just wanted to do it to see what happens i wouldnt have even posted this thread, i would have just done it. But it makes no sense just to do something to see what happens unless your learning from it.

But on the other hand if someone doesnt deal with or know about a product, then there is not much support they can give. I do understand where your coming from on that point.

Im learning speakers and been running active for months now and just got a little bit of info down now to where I understand it better. Still dont now 90% of the things out there, try going to these websites and just start soaking up information. He is not saying we arent willing to teach you or share our experience with you but it would take all day and a year. What you need to do is try to get an understanding of it for yourself then when you get the concepts done and do a little practice or apply it in the real world then come with the questions. That way it wont sound like spanish, then they can get to helping you on what you need instead of trying to explain the basics to you which would be a while before yall get to the real material.

**We want you to ask questions but we also want you do to some work, searching, researching, testing, researching and experimenting some more then come with the questions and examples.

It would take more work to pull those JL's off successfully then to go active and get some speakers that were more so designed to do certain type of enclosures for. But if you keep them I would just do what everyone else said to do, the Infinite Baffle (deaden your doors and seal the front wave off from the back wave).

Stop being argumentative. Your equipment is NOT meant to be in an enclosure and it would not be logical to use it that way. It has nothing to do with what I equipment I know, but instead a fundamental understanding of how drivers work and what they will excel in and what they won't. Again exactly why I said you really shouldn't try to put those components in a sealed enclosure.

Your last comment about knowing about a product is absurd, perhaps you've heard of T/S parameters? They will tell the WHOLE story on whether or not something will work sealed, ported or what alignment is appropriate. Audio 101. Experience can help you fine tune, but it is SUPER easy to understand approximately what things will be like without having even tried them.

Why didnt you say that in your first post, thats all i needed to know.

I tried calling JL for the T/S parameters because they are not listed but i didnt get them, like stated above. So i thought this would be the next best place to find out, and it was. Now i have the information that i needed. Thanks for the input.

I don't think you are understanding what he is trying to say. He isn't trying to swindle you into buying a certain set of speakers he knows a lot about. What he did was comment that if you had put together a different set, you could build something nice and to spec for them.

Your JLs work best in IB rather than in some pods. If you want to build some pods, you would have been better suited with a different set of speakers.

[wof131s 10]

Thanks for clearing that up.

some manufacturers recommend IB applications to make installation easy...

regardless on opinions a sealed fiberglass enclosure would yeild the tightest bass

with most components and cleanest SQ....

"only if the fiberglass is thick enough to prevent vibarating or flexing"

one side effect of a pod built to small is excessive mid bass ringing so make them a

little on the large side...you can always stuff them with pollyfill to eat up inner volume

if mounting in the stock location I would deaden the doors and stiffen them up

as well as take any restrictive material away from the speakers path

[///M5 2,833]

Agreed, however, any manufacturer worth a shit in car audio designs for IB since 99.9999% of the installs are done that way.

Wrong. Even outside of most components that statement is wrong. I thought you actually knew what the purpose of the enclosure was.

[Impious 1,476]

That statement is so horribly inaccurate it's painful.

It will completely depend upon the specific speakers being installed. Especially in car audio where the vast majority of drivers are designed to work optimally IB. Most companies want the consumer using their product to obtain the best performance possible from their products. Most car audio companies understand the vast majority of consumers are just going to toss speakers in their door, and as a result design their products to perform best in such an environment.

Are there some car audio speakers that may perform better in an enclosure? Yes, it's possible. But to make the statement that an enclosure will "yield the tightest bass with most components and cleanest SQ" and state it as a fact as opposed to opinion (which is evident from the first part of your statement, "regardless on opinions") is simply a display of immense ignorance. It is far more likely that they were designed to perform optimally IB than in an enclosure.

[deathcloud 6]

I love threads like this... I do learn a lot. and then I go research and learn even more.

ie

google t/s parameters and what it really means and can do

google Infinite Baffle. what is it and why is it done

then compare that to what people say. But yea I swear everyday I learn something new. It is like going to school when I read this forum haha. I like it though so I don't look like an idiot.

I also think that a tweeter should be mounted backwards...max reflectivness for the square wave X- E=MC3

crist dude...if someone states "regardless of opinion" on the internet you Don't take it seriously .....LOL

it definately gave this thread a kick start though....

seriously though...some of the best sounding mids I ahve heard were in tuned ported applications (car and home)

IB can sound really good if one spends the time to deaden and stiffen the door

BTW....

if you drive a Chevy a IB set up will not work because the steel GMC uses creates to may - IONS and it effects the angle

of the flange

Merry Christmas Everyone...

Am not seeing it as an attack, your input on the topic open my eyes to areas that i do need to check into. Its just that when you ask an important question that your needing an immediate answer to and you have someone saying if you have to ask..... It just gets under my skin. If you have an opinion on the asked question just say yes it is or no its not a good idea because...... If this is done, then the thread would go a whole lot smoother.

The problem is other people who are less experienced may read a statement that's worded as though it's fact, when it is not, and consider the information trustworthy. This is how all of those myths continue to perpetuate. Which is why it's important to denounce those inaccurate statements when they are made.
