THANKS TO EVERYBODY

I was able to build my own subwoofer box.  I came on this site after hearing about it from others, and I must say you guys helped me more than i thought you would. 

I initially thought that asking you guys for sizes and specs. I would just get some rough ideas or no answers at all. 

What I got was an education in:

 how to figure the volume of my cabinet

 to how to tune a port to 30 hz

 as well as to using some math skills I have never used before

you guys didn't just give me the answers but helped me figure them out myself.:D

to all the noobs who are expecting easy or quick answers to their box sizes and port sizes, it's probably not gonna happen. 

if you are lucky enough, what you will get is a good education.

I did.

I know my box is nothing special but its my first, and i am happy with it so far.

16" high x 34 1/2" wide x 17 1/4" deep

port opening- 1 1/2wide x 8 3/8high x 13 5/16deep

made for 2 12" jbl subs

each compartment is braced with a 3 1/2 " wide(cross-shaped) piece of mdf

liquid nails and 2" screws(pre-drilled)

1" mdf construction

HEAVY AS F#%K-------- 101 LBS  UNLOADED

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Nice job.  One question (you knew ther'd be one, right?)  How much space did you leave between the entrance to your ports and the back wall of the enclosure?

Super! kingpin.  Glad you shared the pic.  Now for the carpet....   lol  Keep the forum posted, and soon you too will be doing the schooling.  And a real nice post, BTW.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

yup, good ole slot ports.

i actually think that the slot ports are more asthetically pleasing than the round ports(imho).

Yup, I agree.  The Japanese call it Feng Shui....harmony in design.  Yin and Yang.  That sub box will make you feel good.

Sorry about the last post, I am not sure what happened.
 
Here is what it should have been -
 
Nice box, I wish I had the12volt.com when I decided to build my first box.
 
You had the chance to learn to build a good box; and I only had a sheet of 1/4 in fiberboard, a handsaw, a hot glue gun, some random nails, and knowledge of one side goes to the other side and then to the other side.  I would have been better off putting it in a cardboard box with some duct tape.
 
But hey, I was only 14 and didn't have anyone around to help, so what are ya gonna do?
 
Keep the cycle of car stereo enthusiasts alive, and I'm sure we will see more from you.  Once you build one, you are never happy as long as you can still build more.  Sometimes I will just sit down for hours and design a new box based on the thiele small parameters of a sub I do not even own, just because it is fun
 
It's sad when the only reason that you can find to sell your car and upgrade to something larger is because you have ran out of room to keep expanding, and improving (some may beg to differ, because it is possible to improve without expanding).
 
I sold my first car over a pair of 18's, but that is the fun, constantly keeping your system to your own standards; I just have very high standards when it comes to my own system.

eh? what did you just say?

thanks for all the cool comments guys.

i hope you don't shoot me for the quality of the components i am using.

they are jbl gt120's.

this is the way i figure it.  the gt120's use a pretty large box.  looking at some of the better quality subs they don't seem to use as large of a box. so the way i look at it if i dont like the jbl's it would be pretty easy to upgrade to a better sub, and be able to adjust the volume inside the box.  each side of the box is a seperate 2.39 cu. feet so putting in extra baffling or cutting the box down is much easier than having to try to make th box bigger.

being my first box i didn't want to go crazy spending so much $$$$$  on the subs, until i can critique my own box building skills and hear how it sounds.  i actually am getting ready to drill some holes in the front baffle for the t-nuts so i can mount the speakers.

SH%T, i forgot to get some 1/4 foam to put under the sub to seal it, oh well back out i go.
