I want to run an RCF L10-750YK (10" midbass) into a large horn with a throat that will compress it a little less than 5x. I was planning on putting the driver in a sealed enclosure, but when I enter the data from its specs into the enclosure calculator on this site I get .12 cubic feet, which could not even fit the driver in it! If I made it a 10" circle it would be 2.6" deep! Is this because the driver isn't compatible with this kind of application?
Before I ask questions about the closed box calculator, horn enclosures are not the same. You would be better using hornresp for this.
I assume then you don't need help with the closed box calculator.
OK, you have options to run it on your mac. Is wine, or a virtual machine possible?
What do you have in mind for your horn?

3.4 litres.
This is common with low Q low Vas drivers (i didn’t look at the specs), often intended to be horn loaded.

I own the driver as a backup from a cabinet I used to own, which had a horn similar to the horn I'll be installing it with. So that tracks (it is intended for horns).
But that's a volume smaller than the volume of the dimensions of the speaker. So does that mean I just box it in tight? That's easy enough. It seemed crazy at first (unintuitive) but i am new to this.

Make the box of a size that after you have fitted it, there is 3,4 L for the membrane to breath into. VAS does not include the driver volume itself.

its a moulded horn, here's measurements I have...
7.75" throat with 5.25" phase plug, mouth is 21"x14", 18" deep
it was built to work with a custom driver similar to mine and if these don't work out I have the option of going with the drivers they were packaged with originally.
The original cabinet is all horn (10" mid is on top) so based on ITS dimensions it looks like this one is an inch wider and a couple inches deeper and about the same height. The horn is spec'd wider dispersion so that makes sense. The only notable difference is that the phase plug on the original is HUGE. Oh and the new horn doesn't have the constantly shifting curve (I don't l know the term for that!), just one angle switch near the mouth.
