I'm going to build a ported box for a couple of RE 8's and it'll be about 1.15 cu. ft. But I'm not sure what size to build the port. How do I figure that out?

use a single 4" port, the length will depend on your desired tuning freq.

i did a ported enclosure under my rear seat for 3 re-8's.

that was a couple years agos,so i cant remember the volume,but it was bigger than spec, about 1.65 total.

to calc the port, use this program, it automatically subtracts port volume displacement from your box dimensions you enter.
