box help non noob question

[tacovic 10+ year member]

ok so i cut my wood for my box and figured out i messed up on some of the measurements. the box is alot smaller than i expected and is not utilizing alot of space in my trunk. now i want honest anwers and i know bigger=louder.

im wondering if it will be worth making a new box that will be a little bigger

the current measurements on the box i have now is this

15x32x12

and this is the max measurements i have to work with

20x40x15

is it worth making a new box with the bigger measurements?

will it be any louder?

by the way its slot ported to 39 htz and its for a hdc312

thanks in advance

meh that's kinda tricky... it'll definently be bigger, but not to much

i say hook it up and see how it sounds/how you like it

your box right now is like 3.3 cubes, the one youre thinking of making is just under 7. how did you mess up that bad?

anyway, idk, if that sub needs 7 cubes all on its own, but 3.3 before taking into account port/driver displacement will likely leave you just under 3 cubes.

if i was you, id make a new box, but maybe around 4 cubes after taking port/driver displacement. 7s kinda big IMO, you can have heat issues with the coils if the enclosure is to big.

**edit, just realized it was the 12. you should be fine with the box you just made. could be a little bigger IMO, but id try this box first considering its already made. and make sure your port cut outs are all correct now as well. your box tuning could change now since you said you messed up on some cuts.

for a 12" i say keep your box you made

i really dont think the new measurements is 7 cubes

it is only like 1/4 bigger so it cant be double the size

15x32x12= 5760/1728= 3.333333

20x40x15=12000/1728= 6.944444

keep the box you made. how big was the box you wanted to make? I don't think it was going to take up all the available space.

**** your right didnt seem logical to me

so whats the biggest box i should use for my 12 considering its gonna be getting 1700 rms

15x32x12= 5760/1728= 3.333333
20x40x15=12000/1728= 6.944444

That's not taking the wood into account... I'd say the box is closer to 2 cubes maybe 2.25 after port and driver displacement.

ehh, id just use what you have for now. go easy on it at first and as long as it sounds good and you dont smell coils, id just forget about a new box.

that's alot of power for a 12" regardless, not sure the power handling on the hdc312 but i think it'll be fine

i mean my 15" L7 is in a 4ft^3 box (after port/sub dispacement) at 38hz, 36x24x14 and it's nice

i say use it, if you have it, why throw it away without listening to it

hes right, i was jsut giving a rough estimate. id still try the box you have built right now. either that or tear off the side walls and make it a few inches taller. you wont have to make a whole new box, but will gain some extra space.

if its all sealed up though, again, just try it and see what happens. worst case scenario, you have to build a new box.

ya the AQ can take that no problem

i just measured wrong with the space i had i didnt measure wrong for the cuts so the tuning is still right

so i have all the wood cut in my garage i just need to put it together

i guess ill put it together and see how it sounds
