k old_school, i *think* this is right, after the talk we had.
i couldnt get the box volume to 2'^3+driver displacement with the port at 30hz, so i had to raise the tuning a little to keep the sencond port wall short enough. so i got the box to 2.14'^3, and the port is 34"-1\2 width (like you said)
but im not sure if that second wall is the correct length. i dont think you actually told me what to do to compensate for the turn. you just told me that the second length had to be shorter to compensate for the turn. lemme know - thanks mang!
and see how i did it with cad, i draw the box relative to the size, and i ignore the wood and i only worry about the internal dimensions. makes it much eaiser.
