[QUOTE="BASS OUTLAW, post: 534150, member: 554232"] CALCULATIONS/ FORMULAS dV = is the required diameter of port in inches. Fb = is the tunning frequency of the enclosure in hertz. Vd = is the volume displaced by the driver (woofer) Lv = is the LENGHT of port in inches. R = is the internal radius of vent tube Vb = is the internal volume of the enclosure cubic inches. PS : to convert cuft into cubic inches value of R and "a" is the area of square vent = Width*Hight changing Round vent to Square vent and Pi =3.142 [/QUOTE]
