If using cab as kick, above scoop, is it 4PI for 1x cab, 2PI for 2x ?

4pi = half space

2pi = quarter space

to add 2 cabs in horn resp i think you change driver arrangement....... its been a while since i used horn resp...

sim at 4pi with doubling the cab is like sim at 2pi.
on akabak you can sim different cab arrangement. flipped, or one on top etc...
I'm still an hr hero but... an akabak avenger too

so 4 pi is like 2 cabs, 2pi is 1 cab!!!!!! do you need to change driver to 2 in 4pi!!!!!!!. I never rearly took to horn resp, i went from basebox pro straight to akabak.

1cab@0.5pi=2cab@1pi=4cab@2pi=8cab@4pi
1cab@1pi=2cab@2pi=4cab@4pi
1cab@2pi=2cab@4pi

easy.

i see, yes compared to akabak, maybe i should go back and have a look at horn resp again....

4 pi is free space i.e speaker system flown.
2 pi is half space i.e. speaker on the floor (this is the most typical for a PA bass bin sim)
1 pi is quarter space i.e speaker on the floor and against the back wall
0.5 pi is eighth space i.e speaker in the corner of the room
Generally using a 0.5 pi setting is unrealistic for a PA bass bin.
To get a sim for multiple speakers display the SPL response, and select multiple speakers from the tools menu.

this's graph measurement when use pa c18-650el new series installed.
