View Full Version : I think I fail at building boxes...

So I decided to try to build my first box ever... It is for my 13w6v2 built to JL specifications....

I cut everything perfectly to the exact dimensions, put it all together, but for some reason i managed to lose .75" in the port width towards the back of the box..


The back of the port is 1" in width, while the part leaving the actual box is 1.75"


WTF is that going to do to my tuning????

I put it in the RE enclosure calculator and it came out to 1.8 Cu Ft @ 26 hz....

so how bad did I fail?

its tough to build a box when you have no experience with wood work or anything like that.

i allways lay things out on a big peice of cardboard to scale so i don't have any surprises like that pop up. might be something you think about next time.

I'll get back to you on if I've failed or not, but I'm building my first box as well. The dimensions are perfect, I cracked the mdf in one spot from using too small of a drill bit, but some fiberglass should fix that. The problem is it is about 0.5 inches too tall and if I stick the bottom plate on it will no longer fit in my trunk.

so your not doing that bad.

If it was supposed to be 1.75 the whole length then I imagine it's going to sound like port noise amplified by a horn when you turn it up.

well i guess the best way to learn is through experience... I still think we should have like a walkthrough on building boxes stickied or something, that would be pretty cool.

MDF is cheap, **** it up and build a new box.

Easier said then done when I already returned all the tools i borrowed from a friend... I'll just buy my own tools now.

do you guys know if the RE enclosure calulator is accurate? because I cut everything exactly how it told me each size should be, and I noticed a few pieces weren't right.

I'll chime in since I don't see where anyone answered your question or where you found out what the problem is...! You put the 2nd port piece on the back (end) of the first port piece instead of on the inside end. That's why it came out .75" short on the width on the rear side of the port!!!
Good luck and fixing that should make it perfect and sound like it needs to sound;)!

I interpreted as him tapering the port by .75" from the opening to the back, but this sounds just as likely, what did you mean OP?

Bingo, lol exactly what I was thinking.

Mmmhmmm.

You're gonna screw up. It's part of t. Take the top of the box off, and fix it. If you cant. gets to re-building :-)

I say see what it sounds like before you throw it out.:)

Not a horrible fail, worse would be a straight .75 missing from one of the sides

Yes thats what i meant, the distance from the back part of the port is 1" away from the back of the box, but the side of the port leaving the box is 1.75".

forgot to include the .75" of mdf ._.


oh well I'll see how it sounds, but it was still a learning experience in itself.

rip that port piece out, sand it down a little, and re-do it. it's possible that you'll break the box up, and have to start over completely, but i've succesfully done it when i first started building. this will teach you to double check before gluing. measure twice, cut once. best rule ever.

hmm... Well i just hooked everything up, and it sounds better then i expected, I can deal with it until i build a new box lol.
