net 1.93ft^3 tuning 83 hz i think. which is way to high
if this is a box for a 15" sub then i would only use 1 4" slot port and make it a little over 3 cubes net
if its for a 12" sub then get rid of the 2nd port. i do not have acess to torres right now but i would download that and play with diff dimentions
