    Icon32 Multiple Ports

    I have a box for an XXX 12 that I am planning and the port length is ~25". If i make a 13.5" (slot) port come out of each side, would this work? or does multiple ports add to the port length?

    The more ports you have the more port area you need to tuned it to the desired freq. Which usually is done by adding to the length. You can also make it wider or whichever.
