Port Design question

[christobear 0]

my box is going to be 7 cubes after displacemets.

box is 20 inces deep (so one port side can be 18.5")

112 inches of port area, 33hz

my question is, can i do two ports, each 18.5"x3" at 12" long for ~33hz

would that yield a net port area of 112 and keep the 33 hz tuning?

if not, how do i go about calculating this?

im going to try to do a drawing real quick to help you see what im doing

ok, so if ports A and B are each tuned to 33 hz, and have a total of 112 sq inches, will the box actually be tuned to 33 hz?

It doesn't work like that.
