Does anyone know if the spec's RE provides on their website, for the size of the box, includes the displacement of the woofer or do you have to add in that extra amount?
I realize you have to add the port displacement, but how about the sub.
ex. 18" SX displacement=0.22cu-ft, and requires 8cu-ft, so should the box be made 8cu-ft or should it be made 8.22cu-ft?

Thanks,

 

When ever I do a box it is after the woofer to get true tunning of your port
