Hi All,
sometimes I wonder, that port dimensions, written in this forum, differ from values that I calculate with LSPCAD from Íngemar Johannson, Sweden.
So help to calibrate my (or your) system.
Let's take a virtual box with:
200 liters (or 7 ft³),
Q=7,
fill = 5% ,
a JBL 2245 speaker and
one port
and let us try what you all find out for the ideal port for getting the lowest possible frequency at -6dB (if 200 Hz are 0dB)
very curious bout what you find out. :confused:
