58.7 57.9 what??????

58.7 57.9 hz for the port you mentioned in the first post... if you want a 30hz tune in a 2cu ft box.. either the box will end up being well over 2cu ft with that long of a port or you will have to limit the size of the opening down to like 2.5 x 6 or so.. and even that will get you a pretty long port. id maybe go to a aeroport instead 4" one

for a round port tuned to 30 hz-4"port by 15.69"length, or 3"port by 8.18" long
