That depends on the clearance in front of the drivers and the excursion they make. To make sure that the accordion surrounds of the two drivers can not touch each other you might want to use a spacer ring between the drivers. I.e. an 18 mm MDF ring between the drivers doesn't hurt the outcome but might not be needed.

How would the FaitalPro 12HP1030 perform in the Cube 15 Extra Extended?

Do you want to use a 12" driver in Cubo 15, or do you mean the 15HP1030 instead?

Yes, I'm curious about the performance of the 12" in the Cubo 15 Extra Extended because it has a lot more excursion. Also, I have a 15PS100-8 to test out the box.
With a removable circular baffle for the 12" to fit the and seal the 15" box opening.

It's not going to do great, do to its very low Vas (even compared to other 12" drivers). Its Vas is low, especially for use in a 15" enclosure, causing a large dip between 60 - 100 Hz. The PS100 will not have that problem (as its Vas is 3.5 times greater).

A quick start: 555, 1500 and 2000 cm2, plus 20 and 65 cm. The Extended part has 30 cm axial length IIRC.

I don't have HR installed, if you learn Hornresp then the numbers will make sense. I would go about it this way: i.imgur.com/2JY1eQ8.png and simulate it as a rear loaded horn (or TH), with a rear chamber of 55555 cm^3.

There are guides/ kickstarts on HR on the web, plus on diyaudio.com/forums I've seen Cubo HR inputs in the past.
