This is another in a series of good designs from you. Appealing in both form and function.
If you could please excuse the diversion though, I wonder why you don't show the large coil inductance effects in the sims?
Now that we know a regular sim using any of these large coil drivers won't accurately reflect a proper outdoors measurement and we know how to simulate them much more accurately (thanks in large part to your own contributions) why not show the inductance effects, or at least show with and without the effect? I can understand showing it without the effect since most people won't simulate the effect on their own and will be confused when your sim doesn't match theirs, but this box with these drivers simply will not measure as your sims predict, as you know. Even with the inductance effect factored in this design sims well so why not show it?
Just for my own curiosity I did my own sims and they look pretty good. It's a simple sim, a lot more factors could be simulated more accurately, but it does take more into account than WinISD.
Dayton UM is on the left, Mach 5 UXL on the right.
In both cases the blue line is without inductance effect, red line is with inductance effect.
There's a considerable difference in FR with and without inductance effect (not that it matters much since almost all in room applications will require eq anyway), but the red line is a much more accurate sim.
