This is the box i'm designing to go inbetween my 2nd row captains seats in the hoe.

It's for a 12" XXXer.

What cha think?? It's real close to the exact dimensions.

The curvy part isn't exactly how i want it, but it came close.

The sides will be MDF, and the rest Fiberglassed. Might MDF the bottom too, not sure yet.

Where should i put the port? Top? below sub? Out back?

Let me know!

i KNOW!!

This is the reason why i want to make sure i buy enough materials the FIRST time.

From lowest point to highest, it's about ..... 30"
From fron to back about..... 40"

10" wide in the majority of it.

i'd do the port something like this.....
you generally want to keep the port and the sub on the same side, w/ a few exceptions (CRX box being one)

not really that hard, just cut the 2 outside peices and the bottom and front baffle, then fiberglass the top part

how will a 12" sub fit in a box that is 10" wide?
12" ring on the front... its fiberglass, it's not really that hard:rolleyes:

how will a 12" sub fit in a box that is 10" wide?

Yea what jelly said.

Only the widest part of the sub is 12.5" actually, then it drops down to like 11 1/8 after 1", then even less as u go down the sub. So it's not untill i'm really 5" into the box where the FIXED 10" comes into play.

So untill then the ring will be fiberglassed outside the 10" width the ength until the sub can fit between....get it?

What about below the sub? Like Right below it? - ofcourse i'd raise the ring up

Or straight out the top like a chimney??

I just dont wanna take up too much more volume, rather use a exsisting wall as one of the port walls.

Along the curve maybe??? :eyebrow:

Yea....that's the easy part.......you know how much resining/glassing and not to mention .......SANDING! Will be needed?

The front section with the sub face, will be fiberglass as well, it will not actually be that straight, more curvy.

This is the port idea i'm LIKING! :yumyum:

Would be a Fiberglassed port, made with fleece and dowels, routed like sort of a conveyerr belt/engine belt ...can't explain.

OR i'll just make ribs same curve as the above using it as a template, n use those to guide the fleece.

Any1 ever use/make a fiberglass port?

How thick would it need to be?

imo, f/g'ing that top is going to be much more costly and time consuming compared to just doing it out of mdf...just sink the blade down on a table saw to put slits in the mdf allowing you to do those contours..its really easy.

Although instead of mdf I would use Oak or some type of real wood, not just a composition. You leave around 1/8th of an inch of uncut wood, cut prob about every .5-.75 inches, and that should give you enough clearance to cut that anyway you want. If it dosen't cut some more out of it. It is a really easy technique to do.

i was thinking that....i'd prob still have to do some glassing.

yeah, but you dont have to glass, sand, fill, sand, fill, sand, sand, sand, sand, and sand..just reinforce the back of the "slits" and youre done

there was a REALLL good writeup i think on this site A WHILE back that showed it.

Make slits in a sheet of wood like so

| | | | | | | | | deep enough but not alll the way through, and it will flex slightly. The deeper the slit, the more the flex, but the more the chance of fing up the flex.

I think it might have been Ramos that did this...not sure, was lonnng ago.

But honestly, i'm thnking bout doing the bottom MDF, and the Top Fiberglass, but glassing the inside, to cut down on the needed sanding/preping to the outside that would b needed if doing it from the top.

thats the kinda **** i cut at work the other day, not hard at all, i made a cut every 1/4 of an inch, but for something like speakers , subwise maybe not 5.25s or 6.50's, i would fiber glass or reinforce the curves.....

Almost like a laminent type thing.

Ok but yea back to the laminent/panel type thing holding the MDF together.

What ya guys recommend for that?

This is for a sub.....so not sure how to secure the structural integrity of the outside unless the panel was of a substance easily be glassed and become rigid....

The panels i'm thinking of won't cut it. Like those thin fake wood panels, or even like a fake tile type laminent.

Understand what i'm saying?

No not yet, still gotta get alllll the details worked out.

Like flexing MDF as showin in the pic above.

If not i'm going to resort to Glassing that section.

all thats holding the wood together is itself, a thin layer left over from cutting it. glass the inside of the bend, oh yeah put wood glue and caulk in the bend cuts

I highly doubt in this instance the MDF is holding itself together. Look at the thickness of the thin layer left.

Also look at the edges of the MDF in the pictures above, u will see some sight over hang of the thin layer.

There IS something holding it together.

Not sure i'd be able to cut the mdf deep enough to where it will flex to the degree i want it to, like in the pic above.

IF it was me, I would take my time and round over all the top edges. Then fleece the entire curved section. If you do the curved section first ( leave access to the inside of the box) you can lay mat from the inside. Then finishing the outside would be a matter of some simple filler and sanding. just MHO though :)

And THAT"S why my friend JU are the MAN!

It wouldda been nice to do the mdf, cut down on the glassing process, but it looks unstable and weak.

Now if only a certain somebody would ship me some from Maimi

I have done the kurf ( relief ) cut method before. If done right, it will be very strong. I'm just old an set in my ways :D But judging by the pictures of your design. Your going to need lots of cuts, and you have to cut different sections on different sides. To much thinking for my feeble brain :D :)

yea i'm sure u have, but do u see how deeeep those groves are man?

I highly doubt, from my experience with MDF that it would hold up to what looks like <1/8" of MDF AND flex at the amount it did.

I don't doubt ya man, just don't think it's all MDF used in the above examples.

It can be reinforced to be just as strong. The above examples have a laminate on the outside. Look closely at the pictures. Especially the outside of the bends where the cuts should be open. :)

Surely, or stronger if you want. Just keep adding structural material. Oh and the speaker that InHuman (or really John Krutke) built in the pictures he filled the grooves with wood glue after bending them into shape. Being MDF is mostly glue, it was plenty strong but again he only put a single 4" driver in there. In your case do the same, fill with glue, and glass them on the inside for some structure and locations to put supports.

Do you know what exactly was used? curious for some other projects i have in mind.

theres nothing holding it together besides that 1/8th" dude. Just fill the slits with glue before you bend it and you'll be fine...
