I know that many A'goners are happy with Wilson speakers in small rooms, but...
While others will disagree, I've always felt that most of the Wilsons I've heard (going back to the original WAMM with Crown electronics)sound like they're "voiced" for large-ish rooms. I haven't heard the newer Sophia iterations, but I have heard the original Sophia. I thought it was a very good sounding speaker with bass a little too ripe for the audition room, which IIRC was a bit larger than yours. My impression was that the bass would probably have been more neutral in a larger room. From that experience, I would guess that the bass from the Sophia would likely dominate in a room with dimensions like yours.
Like I said, others will surely disagree - just, MHO.
