    Ok so i figured out these dimensions that give me a tuning frequency of 33.5hz A volume of 3.97 cubes after subtracting sub displacement, and i think that the RE calculator automatically subtracts port volume.

    Another question is are the measurements i input to the calculator Internal or external?

    Anyone have experience with this calculator that can answer? Thinks alot for the help.
