Design me a box?

[tapout383 10+ year member]

I need a box for 3 Alpine Type-R 12s...probbaly gonna run around 2000rms...Would like to use aeroports if at all possible port and subwoofer back if possible...max dems would be 35w X 26D(or less if possible) X 18h. would like to have atleast 6 cubes not sure on tunning yet.

hmm lets see, 3 12's, 12x3 =36, you have 35 width, not including the spacing and a 12" sub has a 12" cone and sorround, plus the basket, might want to rethink that.

hmmm.. ok soo lets try subs up and port back...

the problem is that to make a box that is 6cu.ft. with sufficient port area, bracing, and factoring in the area the subs will take up, will be a stretch.... unless you have the subs inverted.

here is just a quick sketch up i did...

You said it would be a stretch...now i could make the depth 28 or 29 but i didnt really wanna do that but i can its possible how much would that help?

look at how small those ports are. personally, you'd need at least 2 6" aeroports, maybe 3. That or 4-6 4" aeroports. 3 won't cut it IMO

it isnt built to spec just of what i would want it to look like....so lets say this 3 6 inch aeros...max dem of 18h X 36w x 28d...after subs and bracing and port...how diffcult would it be

with 3 6" aeros you don't have the space. the ports alone would take up almost 2 cu.ft. gross internal space with your said dimensions is 8cu.ft.

Dang...and a reg slot port wouldnt do any good guess im stuck with two 12s //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

i bet 3 4's would be fine but that is still cuttin it close

try 1 18 instead man*. sell ur aaarrrghs and get a nice 18. more cone area than 2 12's but would work in your space better

well it would be either 3 type-rs or two 12 hdc12s just figured the 3 would be louder if i could get them to fit...
