    Central port on a two sub box

    Hi, I've been readin on that board since last 2 months. A currly have a little question about vewnted box making. I'm currently runnign two infinity 1032 sub in a custon made sealed box, 2 chambers. I would like to change that box for a vented one as I need a new sound of bass. Problem is that I would like to have the port between the 2 subs, in a single chamber box, who could I calculate the lenght of the port if the tunel has to make a 90 degrees turn, it's kinda hard to explain the situation, so here's a little paint draw of what I mean. BTW sorry for my poor english

    if your port is 4 inches wide, then when you get 2 inches away from the back wall (half the length) split it out each way, just like in the picture
    you need half on eace side.

    For tuning, imagine there is a wall in the middle of you box cutting it into two. Tune one "half" of your box like normal and you will get the port length you need. See the gray line in the picture.

    To measure port length, use middle of the inside of the port. The blue line in the picture.
