What elements go into a box that make it better geared towards SPL/efficiency? I just ordered a DC lvl3 15" and would like to get going on a box design/build. Will a larger internal volume make for a more efficient box? I have about 4.8 cubes before displacement.
I will also most likely be using an aero port, just for simplicity's sake. How much port per cubic ft is recommended with aero's?
