im building a box for 2 sa12's for my wagon, subs up ports back sounds best with the single I have in now. I want to use aero ports, and I never have before, can any1 tell me if my math is close or not?
I plan on 4 cubic feet after the speaker and port displacement...
.75 mdf
box width-32"
box hight-14"
box depth-22"
sundown says displacement is .14ft3 x 2
I calculated the port displacement as volume of a cylinder, I got .09 cubic feet x 2
I plan on using 2, 4" aero ports 12" long, will that get me around 33-32 hertz?
any help appreciated, thanks
