Need some professional box plans for single 12

[xr650jkallen]

I'm needing help designing a box for a single 12 kicker l7. Main goal for this box is for it to be loud. It will mainly be subjected to rap/hip hop music. I know kicker is not a goto speaker but this is what I have to play with, and really just trying to prove that 1 12 in the right box can sound better than 2 in a prefab. The max size of the box 32 wide x 14 tall x 17 deep. I'm fine with any port configuration. This box will be in a Dodge Challenger. The sub needs to fire towards the trunk and I can put the port anywhere. It can be a t-line, slot or round port. Whichever one will get the loudest. The sub will be on a 1200rms kicker amp.

2.25-2.5 tuned to 34 does good

Yep that's the size of the prefab box that's in the car now.

Op. Kicker l7 like big boxes I'd do 3cubes tuned to 32hz port 3.5"x10.. I don't have sketch up or anything so I can't give you cut sheets but I've done a few boxes to those specs and they just straight hammer!

3 cubes for a 12 wtf?

if you want a design pm me.. like i said depending on power 2.25 to 2.5 is plenty.. the amount of port area needed changes the frequency response. the larger tge pirt the faster the subs unload..

its a square sub. You base your cubic feet depending on cone area as well. That L7 sub has close to as much cone area as a single 15. 2.25 is definitely waay too small.

air space is based off of QES and compliance. kicker recommends 1.75-3.25.. last box I built a l7 12 45in^2 in 2.5 was perfect.. hit hard down low and still had decent top end... smallest id go is 2.25 biggest Id go is 3.. I typically don't like to suggest bottom heavy alignments because you have to typically cross them lower and if someone like a little rock and of the output is non existent.. the 3 cube alignment is for the faltest widest response.

At 3cubes my port calculations come out to 3"x12.5"x40" I get 32hz tuning. Is this correct and is this enough port area? Which direction should I fire the port?

 

[xr650jkallen]

Up.

Ok I downloaded the xplicit audio app and this is the numbers I came up with. How do they look to everybody?

I'm telling ya 3cubes after displacement... That picture u are only 2.3cubes

3 cubes

Port 3.5"x10" tuned to roughly 30hz will hammer

And why is your port .5" and your box .750"???? It should all be .75" if your using 3/4" wood
