[QUOTE="helotaxi, post: 2005679, member: 550915"] You can do it tht way but the way that works the best for me and gets the most predictable results is to figure the final net internal volume that I want and the tuning that I want. From there I figure out two of the max dimensions of the overall box that I can't or won't compromise on. Which dimensions these are depend on the install and the space you have to work with. I can now take the net volume, add the port displacement (including material used to build it) and driver displacement and get a gross internal volume. Convert that from cubic feet to cubic inches and divide the volume by the two dimensions that are fixed. Don't forget to account for material thickness here when figuring internal (gross internal) volume and max outer dimensions. The result will give you the internal third dimension that you need to get both the volume and the tuning that you want. It can be done the way that you are talking about but the math can get kind complex and it is likely that you will end up with a compromise design rather than the volume and tuning that you want.
