Hey everyone. Here is a volume calculator I came up with. I figured it would be a big help for some of the newbies. This site does not have one and all the others seem to. It is in excel. Simply enter in the dimensions (internal) that you wish and it calculates exterior dimensions for you. Enter in the vent size you wish and it auto calculates vent displacement and net internal volume. There is also an area to enter in the driver & bracing displacement. For Sealed enclosures simply set all vent dimensions to 0. The green cells are the ones in which you can enter info. On the second tab one can enter in the list of cuts for their enclosure as well. Let me know what you think. It is always a work in progress.
