ok....internal dimensions 21.5L x 27.5W x 18.5H putting me in the 6.3ish cubs internally


4.5 inch x 18.5 = 83.25 square inches of port area.... port is 22.25in long (call it 22)

external deminsions are 23L x 29W x 20H

does that 22.25 include the turn?

no, the only turn is the .75 inch board 4.5inch away from the back.... port is only that one piece of board

correction on previous i that that was 6.3 gross not net

so tuning now is at a little over 35hz

getting to 30hz would either require you to take port down to 3 x 18.5
or
make the port 33" long which would porb take you under 6cubes

it would take the volume down to 5.8 cubes which would efectively change the tuning again so it would need to be recalculate the tuning once more
