so if the sd = 486, then the Vd is 25.13. so if i want to tune it to 30 hz with 1 port then the dia would be 43.47 cm. thats way too big. what did i do wrong? should the Xmax be /2 because it is p-p or what? im confused. here are the stats if anyone would like to help me out with the calculations: Fb=30 Vb=56 Np=1 k=.732 Xmax=51.7 so what would the diameter and length of the port be using the calculations from www.diysubwoofers.org/portcal.htm? should i make it have more then one port?
