[QUOTE="john253a, post: 7675532, member: 640229"] First draw up the biggest box you wish, And work out the internal volume with atleat 3/4" mdf and divide that by 2 With is for 2 subs Then minus the sub displacement and rough port displacement an you'll have the box cuft approximately. Off then you'll be able to calculate the correct port and hz and final cuft Then if you need you add os subtract volume from the box This is not the best way but does work [/QUOTE]
