    Re: ports ports ports

    does it matter, for a slot port, where you make the "L" at, or could you have like 2" then the "L", and then the other 30" after that?

    Re: ports ports ports

    the L is what you use to determine the port tuning... The port area is the Width and height of the port.

    Re: ports ports ports

    I don't catch ya.

    For bends, measure the port length at the middle of the port. Also, if you use a side of the box as one port wall, then subtract 1/2 of the port width from the port length for end correction.
