Calculate port length w/ bend

[jinjuku]

If the port does not provide sufficient surface area for the air flowing through it there is the possibility of port noise as well as port compression. If a driver is moving enough air that port compression becomes an issue SPL limitations can occur as is evident in many commercial designs. Basically, typical tube ports just doesn't have a large enough cross section for most subwoofers with large excursion.

Ok, I am going to do a slotted port design. Does WinISD automatically take End Factor Correction in account for it's slotted vent option?

You enter the edge correction factor on the port description screen/tab.

I don't believe WinISD Beta has that. Alpha is horribly unstable on my Vista box.
