i talked to jl audio and these are the dimensions they gave me for a tuning of 32 hz for a ported box with 2 12" w3v2d4's.
they gave me the external dimensions of 31X15X19. LxWxH
they gave me port opening width of 2.25
and height of 13.5
they said i needed a port length of 18.5 but to not worry about the port extension
and just go straight back 15.25 and not worry about the port extension. He also told me to round off the edges.
the question i have is will this work for me.
