[QUOTE="j3bus2k3, post: 2640126, member: 556020"] Port Length is [B]Lv[/B] and Net volume is [B]Vb[/B]... How about: Fb=.159sqrt([Av*1.84x10^8]/[Lv+.823sqrt{Av}]) End correction factor [I]k[/I]=1/2(width of port) Or for round ports: Lv=[(8466.4R^2)/(Vb*Fb^2)]-1.463R Fb=Tuning Freq Av= Port Area Lv=Port length R=Radius of the port Those are really, the only 3 formulas you need. If you dont know how to calculate cubic volume, then you have no business designing enlcosures... [/QUOTE]
