[QUOTE="gimpster80, post: 1596650, member: 566816"] I would not use a ported box for this particular speaker. Especially if you wish to compete, it has a terrible alignment for ported yet sealed is impressive. using the following. Qts .66 Vas (ft3 ) 4.9? having difficulty converting liters to feet cubed estimate Fs Hertz 33 Vb (ft3 ) 2.0 cu ft Qtc = 1.22 Fc = Hertz 61 F3 = Hertz 44 although a rather large box for freq production I assume this sub is designed for competition, you would do well with a 2.0 cuft sealed enclousure, just get some power!
