I have a 12 inch bass tube that's currently tuned to 40 hz. before building a completely different enclosure i wanted to try and build a 3d printed port with this shape, changing the tuning frequency to around 26 hz. this is still a rough sketch, i was just figuring out if it would actually fit inside the tube enclosure. the port starts at the bottom side of the tube (i still have to make the flares) and has an helical shape in order to fit inside without hitting the magnet. i chose 26hz because that's the lowest i could go without compromising too much other aspects. i used WinISD to calculate the diameter and length of the port.
