Hi, I'm searching for ported box equations.
Knowing those parameters:
- All T & S of the speaker
- Box volume
- Port Number, diameter and length
- Mas, Cas, all Q (Ql, Qa, Qp), Ral, Rat
Need to calculate:
- Alpha
- H
- F3/FS
- Fb
In the book of V. Dickason there are tables based on alignments, how those values are calculated?
I can't understand well the Thiele and Small papers, can someone explain me the equations?

I looked at the math once upon a time, probably in the 70's. I maybe calculated a sealed box for one wooofer, that was about it. These days it's easier for hacks like me to use one of the many box design programs like WinISD: WinISD to do the calculations. "Alignments" in the old-school sense are more regarded as special cases. With computer simulation all of the in-between cases can be modeled as well.
As I understand it, Hc/Hg and AlfaVC are physical parameters that can't be calculated from the rest. Hc/Hg are often specified by the manufacturer. Alfa depends on the material of the voice coil (Al vs. Cu).
I'm sure someone will step in to correct my errors.
