ok i need help figuring out this equation
Where Av is the cross-sectional area of the port (in square inches),
Lv is the length of the port (in inches)
Fb is the tuned frequency of the port (in hertz)
and Vb is the enlcosure's net volume (in cubic inches).
It's to figure out the length of my ports for my new Sub box
the figures are
Av = 4 or 9 (haven't decided yet)
Lv = This is what i want to know
Vb = 16.5
Fb = 53
Unfortunately i was too busy dickin around at school to pay attention, everyone can remember the whole "how are we gonna need to know this when we leave school" arguments you had with your teacher
well yeah now i actually do need it
