ok i am gonna build a ported box for a 15" brahma and i need to know how many cu ft it should be and the dimentions of the box and how many and how long the ports should be?
My box is 4.5cu' and tuned to 38Hz w/ 2 4" Precision/aero ports. I use 3/4" and braced the hell out of it. The external dimensions are 16"T x 30.25"L x 22.5"D. If you want some more info. on it email me and I will get you some diagrams.
