Ok i have a Kenwood excelon kfc-1202DVC sub and ive got a 1.5 cuft box with a 2"x14.5" opening for the port how long of port will i need to get it tuned to 35 htz. I came up with 26" . My inside box dimensions are 16"x16"x14.5" then i subtracted the displacement of the sub etc.

Any help would be greatly appreciated.

Thanks
