Re: Box Help: port sizes
just use this formula:
Lv = Av*1.84*10^8/[Vb*1728*(Fb/0.159)^2] - 0.823*sqrt(Av)
Lv= port length
Av= port area
Vb= box volume (in cuft)
Fb= Tuning frequency.
But I think Win ISD can also.
is that 2.1 cuft with the port / woofer dispalcement? or with out.
are those dimensions the dimensions of your port area?
