Hey Dave,
Steve is talking about using an amp that can't put out enough power at a given load that is enough to bottom a driver out above the tuning frequency. Thats all I'll say concerning that..
You're a bit confused bout the xmax and modeling. In WinISD, the xmax is one-way linear, which for the 5400 is 38mm. You don't use the peak to peak number in simulations. However, the xmech of this driver is close to 50mm one-way...

Now, obviously modeling a sub can be somewhat different than real life performance, but where am I going wrong in thinking a sub like this could easily take 3200W? It would seem at that level it's only working the driver at about half its capabilities.

No, it would be working the driver at full capacity.The d
I do happen to think that the LMS-5400 and possibly the upcoming 4100 are better suited to passive radiator subs because they seem to like smaller enclosures which would problematic to port properly. They don't need 19ft^3 to work well, you know? And in a smaller enclosure, they can handle more power (like a full 3200W).
