Below the horn's cutoff the system reverts to being a sealed box (assuming the back of the driver is sealed). So you can model and EQ it the same way you can a sealed box. It just depends on how much power, power handling and excursion you have to work with as to how low you can get it to go for a certain output level.
I know in my room I get a +10dB shelf below about 40Hz that almost exactly compensates for my sealed sub's rolloff. I figured this out by doing basically what you suggest - measuring outside, then inside. Although really at low frequencies, I was just measuring inside to see what EQ I needed to apply. But knowing the room gain did tell me how much output I could get at the listening position relative to the max output I measured outside.
