"If a driver is designed to work best in a small sealed enclosure, that typically means it has a very low Qts, which means it won't work well in a large ported design, as the low end will be way too peaky."

A driver optimized for sealed has a higher Q for two reasons:

1) High Mms (which raises Q) will be needed to get a reasonably low Fc

2) Being a single-mass system, it will be overdamped with low Q; vented systems need extra damping to control the second mass (port air/PR)

Yes, but you can use a driver with a surprisingly low Q in a sealed enclosure with very impressive results. How do you overcome the need to add mass to drop Fs? Increase BL and drop Qes/Qts which will make your target Qtc achievable in a slightly smaller enclosure.
