They use the same tweeter, or at least I think they do.
The Imagine T cabinet looks much nicer with the real wood veneer and curves, but that is probably a significant portion of its overall costs.
The X2T is larger and is a three way, so it probably can play louder and with more/deeper bass.
How big is your room? How loud do you listen? Do you use subwoofer(s)? How important is bass output to you for your main speakers?
That's primarily where the differences will be - in the bass, with the X2T being able to play louder and lower with more bass - but
possibly being
a little boomy or muddy in comparison to the Imagine T.
Measurements show the X2T might be a little bass heavy, which you may or may not prefer (depending on your preferences, room size, etc):

Compare those with the Imagine T2, and you'll see that the X2T has higher output in the mid and upper bass, with the midrange and treble levels being about the same between the two speakers:
