So... i'm under the impression you WANT to use these subs for a project, yes?

They have the T/S parameters to have some fun with for a groundpounder. How many subs have you got/wanting top purchase? Car it is/there are going in? Have you matched it/them to an amp? And what do you want it to bang out.... get low? Or get loud?

I'm guessing at the box volume he has three subs, but yeah the post isn't the clearest.

The problem I see in the image is that it shows the box volume as 7 litres. You will need to put the measurements in mm not cm. That will change everything.

The other info that Tiger mentioned would also be helpful.

It says 2 15's in the program so it's not 3, but guessing he is just asking if the box is ok for the 2 15's most likely he meant cm's and its 70L

Isn't 7 cubes a bit big with that sort of power?

[sostok]

yeah thats what i thought..as i say im new to this sorta thing in the sense of not goin by supplier spec boxes....in my head 120ltrs was more toward what id need for a dual ported box....hence the cry for help lol

Looks good, is this for SPL only? Or do you want to play music to? As the port is tuned rather high. For the best of both worlds your best with a 35hz tuning i have found.
