    Ok, Once more, double check my port length



    Effective port length = 25", right?

    Total length, down the center is 28.5. Take away half of the port width (3.5") for end correction, and that gives me an even 25" of effective port length.

    Did I get it correct?

    Nope. Your effective port length is:

    19+3+3+3.5+3.5 = 32"

    End correction gets added, not subtracted.

    Re: Ok, Once more, double check my port length

    Oh, OK. Let me try this again:



    I shortened up the port so it doesn't go clear to the end of the box.

    So now, I get 14 + 3 + 3 + 1 + 3.5 (end correction) = 24.5". 24.5" Is close enough for me.
    I sure hope I got it this time.

    That's correct, but I don't like the look of the positioning.

    Yeah I dont especially like that either but I dont know how else to do it. It shouldn't matter though, should it?

    Re: Ok, Once more, double check my port length

    Is end correction figured in no matter what, even without a 90* bend?

    And I was also wondering:

    I am using Bass Box Pro. So when I have it figured that my port should be 24.5" long, is it figuring end correction? Or does it matter? I guess what I mean is, does my effective port length drawn agree with BBP's port length?

    I'd love to take it all the way to the wall and have one 45, but then it screws with the length.
