Decided to design a ported box

[LightningStryk7 10+ year member]

Alright can somone double check this? Its for 1x 1242D Alpine Tye R Sub

internal Dimensions

H= 13.5"

W= 30.5"

D= 11.1"

Slot Port Specs

Length= 31.21"

Port area= (2"x13.5)=27"

Box Volume= 2.0 ft^3

Desired tuning frequency= 32 hz

Displacements

Sub Displacement= .071 ft^3

Port Displacment= .5739 ft^3

I belive this should be an L port with port wall 1 being 9.1"

And port wall 2 being 17.61"

SO can somone double check this? I belive it should be correct //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

Im running sealed right now and want to try ported. Would 2.0 cubes be to much? Alpine recommends 1.0-1.75 cuft or something like that.

talk to speakerman525 on AIM or Yahoo! He designed one for one guy. I'm doing the same thing so once you figure out the plans can you drop me a pm.

If you could, it'd be greatly appreciated!

THANX

? I dont quite understand. do you want me to pm u if the specs are corect? those plans should only work with a alpine Type R 12 inch sub cause of displacment.
