i am making a box for 2 12s. each one needs about 1.8 cube feet and tuned to 38 to 40 Hz. i got a new computer and it has vista so the thing i used before to find the port size wont work on vista. if any of u guys have a design of a box already like this send it to me! or if any one can help me out in using something online to do this.
i don't have the displacement right now. ill get the specks on the sub today if i can.
