If you go on the re calculator and put in your dimensions, instead of having the port on one side, would the tuning etc be the same if the port was moved into the middle and where the port bend on the re calulator, could I cut that piece in half and add in to each end in the middle port, would this work because I want to try building a box with the port in the middle as opposed to one side. Also is it best to have the port it in the middle or on the side and whats the advantages and disadvantages
