h1= segment 1 throat
h2=segment 1 mouth segment segment 2 throat
h3=segment 2 mout
l12=lenght segment 1
l23=lenght segment 3
get the total volume of both segment because I can't figure how the driver volume is spreaded into them, and obtain value wich consider the driver...but what value have to be moltiplicated by the width?
((h1+h3)*(l12+l23)*width/2-drivervolume)/(width*?)
hope that could be clear.

The PD driver (12SB30) can be used for Cubo 12.

could you post the plot of cubo12? So I'll try to match my sim to the measurement.
cheers, bitzo

edit: I make a mistake in the definition of h6r now corrected in the last file uploaded
edit2: A mistake in l34 now corrected...damn trigonometry

if you want to switch from a reversed driver mount in a straight one you have to:
-In Vtc definition put -drivervolume instead of conevolume;
-In L56 and L67 definition put h6r instead of h6;
-change the radius in the cone area definition accordingly to your driver.
enjoy...

To answer some other questions from this thread, as I finally have the time to do so (it’s vacation so my internet time has been decimated). Making a Cubo 212 with the horn mouth’s together is in my personal opinion the best way to go. You could use a divider panel USB-style, in fact the first Cubo 212 prototype was initially build without divider panel. If phase is reversed for one of the drivers, lacking a divider panel means that the output is reduced enormously. Therefore I would expect that, in the scenario where one of the drivers is permanently leaving this earth (during a performance), output is decreased substantially when there is no divider panel used at all. That would be a no-go.
Adding the beginning of the horn path’s together should work, however for reasoning mentioned above, I would use a divider panel in that case. The same goes for adding Cubo’s side by side.

Cubo

I wrote it because I'm modelling a 10" version for my home theatre system. I have strictly dimension because of furniture. May be should be nice for caraudio too.
