Alright so i need 67.35in^2 and if i build a box thats is 5cuft net i have a port area of 92.50in^2 and tuned to 32hz is this a good way to go?

dv = 39.37 (fb x Vd)^1/2

dv= minimum port diameter of vent in inches

fb= box tuninf frequency in hertz

vd= cone displacement in cubic meters (one way xmax in meters times cone area in meters)
