Mobile Enclosurs recently made me a great box design.
He is highly experienced in the car audio field and has LOTS of knowledge.
Great to talk too, we have over 150 emails back and fourth discussing what electronics would be good for what i would like to do.

finally we got to the enclosure, which is what he is for :)

he made me an amazing design , actually two and let me pick between them :)

Just finished drawing it up and i will cut it out tomorrow, overall, he is a great guy and for the cheap price of $10-$20, i couldn't ask for anything better. HIGHLY recommended.

Kinda confused why he didn't have the baffle lay over everything, it would make building it so much easier

^ he does not build them he has a contract with a legit box builder that builds them suppose to be top knotch. So i guess a lil extra wrk want not matter since he is just a broker of sorts.. Good prices though

Still doesn't make much sense to me.

the bottom is the only full piece - seems like it could have been made easier.

I guess if I had to answer 150 emails for $20 I wouldn't try to make it easy to build either. :)

here is a box designed for me by another box builder (who I think is in the top 2 around this place)

see how the top and bottom are full pieces?
see how both sides are the same size?

That is a what a good design looks like

Make the box 3/4" shallower and drop a huge beauty panel on the front for a flush baffle and you have yourself a winner

In reality it is a double baffle. Originally it was just going to be braced and that was changed after the design was finished. However I built it and shipped it lol.


Mobile is a great guy though, props to him on his designs.

Looks like a good design with the exception of the top plate. As long as Dustin could understand it and build it it should be great. Never dealt with the designer but Dustin can build a great box.

Dustin built my box - he is not building the OP's box.

Anyhow......the positioning of the baffle is done properly. Here is why: Consider physics. With the baffle placed on the top, the strain from the excursion of the subwoofer is in a push pull configuration. There will be a lot of strain of the baffle pulling from the box, even when it is secured properly. Now, when the sub reverses polarity, it pushes on the box...that part is not so bad. Now, as it is, the force from the walls take it and convert it down the sides of the enclosure to the bottom when it pushes down, and when it pushes up, it causes the force to centralize on the baffle, but with the cutout and sub in place, the force goes back to the subwoofer kinetically. either way, there are strong and softer points. It now comes down to whether you WANT to make it easier to build and whether you personally TRUST it that way. And as a designer, I take those factors into consideration when they are an issue. So, saying that this design does not "look" proper, is relative. And has nothing to do with the actual performance of the design. What was done in this case, if you ask the OP was two supports on the inside, that is not shown in the picture. One of them is from the baffle to the port and the other is DIRECTLY from the port to the bottom in the same place. There will be no problem with excursion here. So take the kinetic energy and when it pulls, the supports on the inside support the pull force as well as the sides of the enclosure. With a top configuration, only the tops of the sides support that. here since it is perpendicular force, it is more sturdy when the sub pulls because not only is it taking the baffle up, but trying to take the sides with it.....that is not what happens when you top baffle the design. understood?

I posted it twice, just in case you "missed" it the first time, lol. Not being rude, man, but just done bash my designs without knowing anything about them. Personal comments are allowed and accepted, but bashing vs constructive criticism.....there is a difference.

lol, don't worry Mobile I would vouch for you any day of the week for designs. As always "there are many ways to skin a cat". This is true in just about everything in life.

As I said, your a great guy and a good designer so no worries for anyone going to you for a design.

That top baffle configuration is minimal to performance against the pressure either way of doing it. But it would have been easier to build. Like someone else had said, it doesn't matter to the OP since he didn't build it so whatever. And the internal bracing is not very efficient. Definitely would not have gone with full panels as bracing. But I guess OP was happy so its cool. And the fact that you basically worked for free with as much communication that went into that. I don't even know why you would need that much communication.

You as well Rabbit :) Very well knowledgeable in the field and that is respected as well. Thanks man. Oh, and the design crispin linked to, did look sweet, I admit. :)[COLOR="Silver"]

Actually, yes it is efficient....not for performance but for stability. I could also have added double supports on the port, but it was not needed. The fact that the panel is perpendicular to the compression to the port opening, it does not block anything considering that this design is compression based and not intensity based like a horn is. Most BR designs are compression based. Internal bracing has little effect on the response unless it blocks the output or changes the ft/lbs per square inch in the chamber more than a certain degree.
Again, relative.

I will be using Mobile for all my enclosures i have, ever, in my lifetime haha :D


NO THIS IS NOT THE CAR THE SUB GOES IN, THIS IS THE CAR I TOOK OUT OF TOWN AND MADE IT AT THE DESTINATION.---- just so no one gets confused :D

Mobile - I think you got me confused with someone else in this thread.
The only thing I said was not using full sized pieces on the tops and sides would make it less simple to build.
I said nothing about the bracing, I have no idea what you are referring to and why you posted 2 pictures of the bracing for me to see so I didn't assume anymore.
Can you quote the post you are referring to cause this seems really out of left field to me.


....I just read through all the posts in this thread and the only thing I said that didn't come out right is where I said the box I posted was designed right. I meant from the standpoint of being easier to cut and assemble. I was not referring to how the box would function and I should have been more clear. But nowhere in no way was I talking about the bracing or lack of bracing or functionality of your design.

If you read my post I told the OP that I thought you worked too hard for as little as you charged and suggested he give you some extra money for your time. So attacking me in this post seems wrong.

Well, first of all, if it came out wrong, I can understand your confusion. You have to understand my position to rectify my ability to design and defend myself regardless of the way it "sounded". I am not attacking you, I'm letting you know. Attacking you would be against forum policy. I need those who do not understand about design to understand that every aspect of it is of no disregard to me. And for what I do, and what I have done with design for many years, and the knowledge I have about audio and physics do not need an explanation or excuse as of why things may not seem stereotypical. I am not upset if that is what you think, nor do I hold any personal grievance to anyone. I am simply here to educate. I am no higher of a person than anyone here, but I will not be made lower than I really am either. And with all of the opinions in this thread about how I should have done it different is fine...they are just opinions, but ones that need to be corrected as to why it is ok for me to design the way I do. That is pretty much the idea I portrayed. I accept opinions and understand mishaps and misleading quotes, but when you say, "this is what a good design is supposed to look like"...what does that say about me to the community? It puts me in an open-minded spot to defend my idea, my work. it doesn't matter what it really meant, it matters how it came out. And anyone can choose what they say, it's a matter of choice. You chose to word it wrong. I forgive you.
Now regarding baffle support, there was a part in there that should have been understood, but the other part was not meant for you. It was to the other gentleman that said he would have not used full supports-likely as in those who cut holes in them to make them lighter and cheaper. He said they were not very efficient. That was not meant for you. It was quoted.

The whole point is, you said something against me and I have to defend it to everyone that sees this thread. That is extra work on my part that I do not need nor appreciate. But again, I forgive you man. No real hard feelings. Trust me. Nothing I do here is personal except the thrill of the excitement to work with all of you and when you get a design, how happy you can get. That gets personal and feels great. Everything else is professional. There are people on here for completely different reasons than me and other designers that do not hold the passion I do and do it for the money, but for me, this is my life. If someone says anything bad about me or what I do, it hurts my business and in turn hurts my life. I have no choice but to defend that.
You ok now? It's fine really. No worries.
