Hey all...I have a nice stereo system in my car, but my brother has NOTHING bumping in his Jetta. Right now, I have an Elemental Designs e10K subwoofer (2003 edition) sitting in my room, and I've decided that I'd hook my brother up with it...All he has to do is buy the materials for a box. We want to go ported also. This driver is a 10" subwoofer with about a month's use, and there's no reason it should sit on my dresser!

Could/Would anyone be kind enough to help draw out blueprints on something that will make this sound good and get loud? I'm thinking ported at around 30hz. I've done searches and tried to learn about ported enclosures, but unfortunately I'm too stupid to do this alone. :smash: Any help is appreciated.

Specifications e10K e12K e15K

Qts. -.34
Qms. -5
Qes. -.36
Fs. -28hz
Vas. -35 L

Re. -1.75 Per Coil

Oh, and these are the only specs I could find on eD's site.

Thank you. :*******:

Well, right now he has a 1989 Wolfsburg Edition Jetta. He has probably about few cubic feet to work with. I don't think that the box will need more room, but it's probably around there. I'd give exact measurements of his trunk size, but he's out at work right now with it.

I'm guessing about 1.5' high x 2-2.5' wide x 2' depth. I could be wrong...but that's just a guess-timate.

k. lemme see.

box volume= 1ft^3
port tuning= 33hz
port size = 8in X 2.5in
port length =45.4"
port volume =.52ft^3, port volume with wood thickness = .99ft^3
net box volume =1.99ft^3 (after port area\driver)
.75" mdf box size =16x15x15

i think thats it- can anybody verify that? im still learning and im trying out what ive learned.
