That's perfectly true, if you use an amp with a high damping factor and/or a lot of wall absorption. My interest is in SETs, which usually run a DF around 2 to 3, so I added that calculation.
And you're right about the efficiency too - I mistakenly applied a 20xlog efficiency calculation instead of 10xlog to the claimed 1.4% 2-pi efficiency. So yeah, 93.5dB/m/W. The spec sheet claims 95dB, which seems to be in the 800-2000Hz range, well above piston behavior and only on axis.
I stand corrected.

I did model the foster 12 and 15 but they drop around 60 hz
