Sub Box

[Millslane]

lol, i can see it now randy. drive a little too fast and the box flew into your person? lol, hopefully it healed into a cool looking scar that you can tell your children about someday.

yes yes, of coure. it covers up the mistakes, if any. i knew i forgot something

[RandyA]

yeah thats about how it happened i didnt have it secured down properly.... and theres not to much of a cool scar. the doc did a good job with the stitches ...

Wow, again, thanks for the info guys!

RandyA - i must have looked at that page 100 times and havent seen that little link there...haha.

uhh..the board i got is like MFD or sumthin..lol it is 3/4" thick and wasnt WHITE..more like a brown or tanish. the guy at the store said that thats what guys get when they build there boxes.

So now i got the dimentions on how big a square box has to be for my sub. But im going to have the sub angled (look at pic at first post). So how do i figure all that in?

Thanks again,
Tippy~

Tippy, take away a few inches on the front, and add whatever you took off to the front. this is an easy to keep you close to the same inside space, and give you and angle.

example, if your box was going to be 1 foot tall, you can make the front panel 8" and the back 16"
do you see where i got that?

I think this will work. anybody see any reason why this wouldn't? or have a better way?

JL calls for a 3.0 cubic foot box... 3.0 cubic feet is 5184.001889295577 cubic inches give or take go to www.metric-conversions.org for the converter, and go to volume conversion... i cant figure out what the dimensions should be but what millslane said should work or you could try adding it to the depth i dont know. this is the part i let my brother figure out since he works on this type of thing for a living. but he's away at school and i havent been able to get ahold of him... i hope this helps some

There has got to be a formula for figuring out the the area of a non square box.
If nothing else, figure out the area of the rectangle part, then figure out the area that slopes, as if it where a triangle? That make sense?

To answer Electricity's question, there are formulas to figure out the exact internal volume of any curve you can imagine, but that's getting into Calc 2 and I think it's overkill for what we are looking for. Plus, I don't have my college notes and I don't remember the formulas that we'll need.

Tippy, I put this together during lunch but it's not perfect. It's based on the D2 model. Keep in mind that these diagrams are not drawn to scale and I estimated some of the measurements based on what I remembered from school. I didn't have time to calculate the new length of the box since you'll have to make up for the loss in volume from the 45* angle you want the speaker to sit on. I figure it'll be between 26"-28".

OK, good luck, man. I wish I could do more but we've been a little busy here at work.

WOW! THANKS ALOT MAVRO!

Thats flippin sweet!

and almost perfect. I think i will makt it a little wider.

Im gonna draw somethin up in a day or so. Ill let ya guys know how its goin.

Thanks again,
