WinISD clarification

[hockey512546]

Just need some clarification on winISD..

If I were to build a 2.2 CF ported box @33 Hz and have:
Two 2.98" diameter ports with flared ends on both sides the port length calculates to be 13.31"; is this net length, or is this saying each port would have to be 13.31" long?

Each port

how do you change units in that program, it defaults to metric - want it in cubic feet

i have bbp6 and i set up english instead of metric when i installed or ran it the first time iirc.

and why would you want a 2.98" port? i hope to God that you are calling that 3" and your port 13.25 lol, just to make it easier to cut :-P

@BassMechkanic
click on the unit itself, like it says mm click on (mm) and it will change to another unit.
