Sealed team.
Hello, everyone.
I'm going to retire my Tannoy system 600 + centre sound bar, in favour of some unused Alpair 12P, for a 2.1 movie system.
I get a calculated .25 foot sealed enclosure for an f3 of 104 hertz, and a qtc of .707.
Does this seem TOO small an enclosure to anyone else?
It will be highpassed at 130 hertz, but still seems Sam.
Am I risking harm to the driver?

.25 cu ft = 7 liters does seem pretty small for this driver - would it even fit in a box that size? If high passed where you've intimated, I can't imagine you're risking harm, but I'd be inclined to go with one of the larger volumes seen in Dave's modelling - 14liters= 5ft^3 shows yielding just under 90Hz resonance, and is still a pretty small box for a driver with an over 8" diameter frame.
Trying to get the metal A12 into a 13L box was a challenege and led to the trapezoid miniOnkens.

Yes, I remember, and that turned out how, exactly? 😉 Of course the 12P is an entirely different animal, and since MIT appears to already have the drivers, it behooves us to suggest something that will work reasonably well - I just think the smallest possible box in which it will fit isn't the optimal way to go.
Mar-Kens for the A12p are 13 L & 17 L, the later being optimal for the miniOnken alignment.
Large would be the Woden Avebury back loaded horns.
