ok im trying to do 2cf@35hz i have 2.52 after sub displacement and im trying to add in the port displacement, but the longer i make the port the less volume i have, and i have to keep making it longer and longer to keep the same tuning, which also keeps making the box volume smaller and i just keep repeating this over and over
