I am building a 2.53 cubic ft box for a 12" sundown x12. i am putting it in a narrow space, so i am going with an external aero port.
My question: how do i secure the external aero port to the box?
i need a port that's 46" long for 8" diameter. i was planning to route about 20" inside the box, then the remaining 26" on the outside. what parts do i need to do this?
i was thinking of mounting a pvc pipe coupling in the middle of the board of wood (where the hole is) and connecting one side to the inside of the box and the other to the outside. that way i can change lengths. how would i secure this in the box, so it doesn't gooch out either way when i am bumping?
my other option is using a 6" port, but that would put me at 28 in^2 of port diameter, which is 12 less than the required 40 in^2. in comparison, a 8" pipe puts me at 50".
please guide me either way regarding the 6 vs 8" port. the 6" requires less length.
also, how do i secure the pvc pipe in the box, mid port?
