@petzzz I'm puzzled by your statement about bass in your 12' x 18' room, and I don't think you necessarily have to rule out some bass depth in your speaker.
I had TAD CR-1's that performed very nicely in an 11.5' x 15' x 8' room, including with tight, fairly deep bass. To achieve this, I did have to employ a decent number of DIY rockwool insulation absorption panels to tame the room modes, but it worked rather well. It wasn't very expensive to make them, but it did require some creativity to mount them effectively in the room. Now that I have a room twice the size, my TAD's do breathe a bit easier with more depth and soundstage, but I would not characterize the bass as necessarily "better". (Still working on the acoustic panel tuning of the new room, though.)
All that said, I'd love to experience the Magico Mini II in my system, too... They seem to be a decidedly interesting speaker.
@jbrrp1 Thanks for the pointers... I have not done any bass treatment to my room with my SF auditors as I don't seem to have issues but I'm a little cautious in taking on larger speakers because of bass. It's just a precaution but if I like the speakers enough, I'll have to learn more on bass control :)
