3" to 2" port length size

Hi, Could someone be so kind to work out the port length using a 2" diameter port tube instead of the 3" in pic.
Cheers

A 2" port is likely to chuff. Are you sure?


Other than that, a 3" port with length of 9.95" can be replaced by a 2" port with length 3.93".

However, WinISD indicates that the port length is off for the given cabinet volume and port diameter. For a 3" port it calculates a length of 12.2" and for the 2" port the length is 4.93".

Thanks for the replies.
TBTL... I might give the WinISD port sizes a go.
