ok so my box is almost done thanx to being put off by Fay... anyways this is my first wall build formy 3 15" dreadnauts, the box has alot of curves and cubby holes on the inteior so I could get the most air space possible, I had to frame in the wheel wells and slant the side walls and the back wall, its going to have a top port and have no idea how wide and long to make the port, there is about 9" on the top of te box and then slants maybe 30* to the back to make room for the closing hatch then goes flat, I know I know pix would help but cam got fuxored from water damage! hopefully someone can decipher what the F I am saying lol... anyways the port would have to go flat and then curve with the back wall I know I wan my tuning low, like 35 hz... just dont know how the hell to calculate it box is about 20 cubes before speakers and bracing and port so im thinking like 15 cubes after all that...
