ok, im finally getting around to building the box for my 2 12" Rs tomorrow.

5.5 cubes, 32 htz with a single slot port yada yada

when i calculate it on subwoofer-tools.com (yea im lazy), they recommend 61 in ^2 of port which seemed a little low to me.

Should I just go by this or take the time and do a new design with 70 sq in of port area?

I've heard a minimum of 25in^2 per 12" Type'r so 61in^2 and 70in^2 are fine...
