2x15 kick cab design

Sure, by default akabak take 2pi. But you can set the ground distance adding y= tag to the radiator but it's not a true ground coupling but imho can give you an idea.

@Bee, this cab seems to kick pretty good, I wonder what could happen with my rcf 15mb501. In this layout have you reduced the rear chamber by adding some corner brace? just because you can port it in order to drop lower.

I'll explain it to newbies then. the output shown on Bee's graph would be with the kick cab on the floor/ground, NOT stacked high on a bass bin where it would be used

yes sorry mykey should of said it was simed in 2pi in akabak, ill do a 4 pi sim tomorrow, to port the rear chamber would mean a port on the back of the cab, ill do a plot with a port. Original it was designed to be used for dance type music, a port would drop it lower......

Does AkAbak include directionality? Afaik (from memory), a single 15" in a horn like that should be able to hit ~104 - 105 dB from ~120 - 150 Hz and up (when directionality is included in HR) in 4,0 pi.

If you port it, you could leave the panel out that minimises the rear chamber, making driver acces easier also.

this is true cubo, ill sim it with a bigger rear chamber, and port......

will it

in theory it should, but its doing the opposite in akabak..... interesting..... by making the rear chamber bigger allso worsens the plot..... ill play a bit more and see what i can come up with......
