Torres v/s Bass Box Pro v/s WinISD
I recently built my enclosure for two Boston G1's using what the Torres Calculator told me.
2.3 cu ft
two 4" ports 24.75" long. I had to go to these sized ports to the the port area into the port area range that Torres recommends.
Today I was modeling it in WinISD and Bass Box Pro and none of the numbers match on the ports.
2.3 Cu Ft
32 Hz Tune
Bass Box Pro says two ports 3" diameter by 13.26" long
WinISD says two ports 3" diameter by 13.91" long
Torres says two ports 3" diameter by 14.68" long, but the port area range is well below the recommended. So I assume that WinISD and BBP are below the acceptable range as well. I know the rule is 9" to 13" of port per sq ft of enclosure, so which one is right? I am wondering how far off my enclosure is now.
