12" Axis enclosure help

[Gavriley2007 10+ year member]

well i am ordering a pair of quad coil 12" Axis's tomorrow and will be porting these in my wagon.... i used to run my old 15 sub up port back, should i do the same for 2 12's, or do i do sub back port back?

also these only need like 2 cubes or less right? tune to 30hz im thinking

anyone wanna do a design for me by any chance i would be grateful once the subs arrive i will build the box and start bumpin.

Max dimensions?

Id stick with subs up port back. AP recommends 1.2 - 2.1 cuft ported.

 

[Gavriley2007 10+ year member]

max dimensions is:

37" wide

21" deep

height isnt a problem especially with the enclosure these need shouldn't be too big

This will bring you to:

-2.13 cubes net

-tuned to 29.9Hz

-37.5 sq inches of port area

sub and port back, port cenetered between the woofers.. anywhere from 1.5-2 is ideal.. 30 is plenty low.. most music never goes under 40hz most, maybe 1 out of 10000 songs drop below 35hz..f3 should be around 26-28 with that aligment.... sub up port back does good for burping.. spreaing the woofers the width of the cabin helps pressurize the cabin as a whloe instead of tring to pressurize the dash...

do 4.5 cubes, 30-32hz tuning, around 80-85 square inches of port, and give it lots O' powa //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

try a tad bigger //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Alright, here's one for both of them...It isnt perfect because it isnt tuned as low as you wanted //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

But it comes to:

-2.12 cubes per sub, net

-39.375 sq inches of port area per sub

-Tuned to a hair under 33Hz

Any Q's just let me know

sry i didnt make it clearer it was for a pair, and yea SBeatz i ordered a pair, im thinking a vfl 500.1 is the future somewhere

 

[Gavriley2007 10+ year member]

at like 44lbs i should double baffle for sure right?

I usually like a double-baffle with my subs or you could put some bracing on the back of the baffle and it'll do pretty much the same thing
