At least, that's my understanding as I have been researching what the best mid-priced 18 would be for a 4 ft^3 sealed enclosure. Now, the first graph on data-bass makes them look very similar, but when you read closely you will see that the UXL was starting to complain at that drive level, and the HST-18 had several more db's in the tank before running out of excursion. Look at the max long term output before compression and the difference starts to show up.
It is called a higher x-mech. I am impressed with the quality of the even the SI-18HT.
