I prefer the veneer style of the F2 which also seems to match your other furniture better, but I prefer the more balanced aesthetic of the driver layout if the Q11.
Very much looking forward to hearing your listening impressions.
After a couple hours of listening, I do have some impressions. Prior to placing the Q11's, I had my wife listen with me to a few familiar songs with the F2's and cranked it up a bit. I then placed the Q11's and listened to the same tracks, increasing the volume to match that of the F2's. The F2's do indeed seem to be more sensitive. My wife said pretty quickly that she preferred the Q11's, but didn't state any particular reason why.
I first played Dire Straits Money for Nothing, so as to listen to that increasing in volume drum solo at the beginning of the song. To me, the drums sounded bigger and fuller with the F2's, but more precisely located and defined with the Q11's. Somehow, the Q11's just seem "faster" or "snappier" than the F2's, overall.
I also listened to Malia's Convergence album, which showcases her sultry vocals and also has some really deep bass in it. Again, her voice sounded a bit "fuller" with the F2's, but the soundstage was better with the Q11's. I like the sound of her voice with the F2's but the placement of the instruments and accompanying vocalists is just better with the Q11's.
Another difference is that the bass notes, although not as "big" or "full" sounding, seem to have more tonality with the Q11's, allowing me to hear more of the bass "line". As to the treble, it seems that the F2's are a bit "hotter" with the highest frequency content. I can hear the highest high frequencies better with the F2's. But just below the highest frequencies, the Q11's seem to have more clarity and precision.
Soundstage -- I would say the ability to throw a believable soundstage is the biggest difference so far. With the Q11's, it seems like there is more delineation of instruments and voices. And the "micro dynamics", if that is a thing, seem "faster" and better with the Q11's, as if the drivers are just better. I was initially concerned about the small tweeter and mid-range driver of the Q11's, which may contribute to the drums sounding "smaller", but I think these drivers may offer advantages in terms of "speed" and soundstaging.
I will have to continue listening for some time in order to gain a more complete impression of the Q11's.
