Aeroport question?
 

Hi y'all!
Had a question on aerports. The box for my 2 HDC3 15's is on the average size. I wish I could go bigger but I cant.
I have them in a ported box with two 6' aeroports at full lenth with flares
at about 34Hz I believe. The external dimensions of the box are 34"x32"x15"

Now Id like to move a bit more air, and I know it may be counterproductive to run more ports which take up extra space, BUT if I ran an extra 6" aeroport but tuned to the same, would I feel a difference in the bass since more air would be exiting the box with 3 aeroports instead on 2?
Just curious Thanks!!!
