This box is for my 12" L7. This is my first build ever. I used 3/4" MDF, its not too good, but it will work.

L7 is Dual-4ohm. It's going to to run by my Hifonics Bxi-1500d @ 2ohms.

Its 3.4cuft NET. Tuned to around 29hz, nice and low. It's really short in height because my trunk is short. Not much else to say...The port is 6x4x16 with a brace under the sqaure port to hold it up.

Nice Cuts! I think :oops:

Thanks, mind you, the pre-fab is sitting on its back making it look smaller, but it will definetly blow it out of the water.

Why that method of port design? Why not take up the length of the box like the prefab box did..

I wanted to try a square port, and see how it was. The slot port is seen everywhere, wanted to try something different, even though there is nothing wrong with the slot port type.

There is a reason though why the slot port is superior. First, it takes up less Vb and more importantly, it adds bracing to the box.

My friend has a prefab box like that and it ***** balls on the low end.
Any program to figure out what its tuned to?
Nice box....wish i could build that clean.

thats true. but by building a removable square port one can experiment changing the tuneing of the box by making th port longer or shorter.or have differnt he could build a few ports for it and it set up so has one for daily driving and one for comps/if he really wants to show his friends how loud it can get :cool: nonetheless good job on the box, next time i would use a bit more braceing

Yeah, too low for a 12" L7. Also, with a slot port, it's typically better if your port is all the way against a wall. For example, my original box design for my 4 12" L7s had my port in the middle, but when you have the port in the middle, you losesome SPL and response because the air "has to find the port". By that I mean, if you had the port against a wall, the air is forced in one direction only and will leave the box much quicker vs. a box with a port where air can go completely around the port. Now I doubt that it really makes a noticeable difference, but I've been told that several times, so now my box for my 4 12" L7s has the port against the wall. Other than that, you have a great box constructed.

What do you mean its too low? What will it affect? A guy with 2 L7's has his box tuned really low ~30hz and he says it sounds AMAZING!

And thanks for the compliment!

That's what a slot port is. His box is a standard ported box. Not a slot port...

I had the first box you had and its tuned to 44hz.........

Also 12" L7s like 35-36hz to make them loud.
