[QUOTE="Jester1318, post: 1680673, member: 563550"] For those of you familiar with bass box pro and/or winisd, help me out here. The box is 2 cuft tuned to 30hz (12" rlp), 4" precision port When I do this calculation (Lv=((8466.4*r^2)/(Vb*Fb^2))-(1.463*r) I get a number like 15.89". Winisd gives 16.28" with end correction being .614 (is that right for 2 flared ends?) And Bass box Pro gives a length of 17.35". Which of these is correct? Or is there some other part if it I am missing? It seems as though they should all be the same length if my numbers are identical, but they obviously are not. Also, a precision port ordered from PE is 17" in length with adding the flares and not cutting anything, correct? Thanks [/QUOTE]
