Box design 4 12"W6v2 with 2 4" Aero ports using Torres calc


piccolo

Recommended Posts

I am building a box for my Lexus is300 sportcross (wagon) and need some guidance. I measured my rear again and again and came up with some pretty solid figures. Everything in the picture is drawn to scale. I tried using the Torres calculator (which I will link) to tune the box. Im trying to use 2 4" aero ports seems like the easiest thing to do. Please let me know what you think of the design and the calculations, any feedback is appreciated.

Nowhere near enough port area. What you have is a leaky sealed box. Two 4" ports has about 25 sq in of port area. JL recommends 18.5 sq in per sub and depending on the specifics of your setup that number might be low.

Can you make the box any bigger? With 6 cubic feet of net airspace and three 6" ports your ports will need to be about 32.75" long to tune you to 32 Hz.
