As someone with a system in a loft with concrete floors
(see also system link below) some advice:
1) Get a thick real wool (not petrochemical) rug for between the speakers and sofa. And put a natural-fiber rug pad under it.
2) Ditch the coffee table. It's at least as problematic than the floor itself is. Possibly more so. Ideally, replace with plush ottoman upholstered in breathable cloth.
3a) Look for speakers with some vertical directivity control for the mids and treble, to keep floor-bounce away as much as possible. That means waveguides or concentric drivers, or at least an MTM driver layout. (A line array/CBT might work well in that room too, but any decent one would be way over budget.)
3b) However, the catch here is that because of the distance between your side-walls and the listening space, you also want a very broad horizontal pattern. Otherwise, while image focus will be very intense (unrealistically so, in my experience) there will be little spaciousness to the sound.
4) Keep the mids and tweets (or concentric mid/tweet) fairly high off the ground.
5) Add surround side and surround rear speakers placed well if you can, and listen to music in Dolby Pro Logic II to reclaim some of the ambience lost due to the far-away sidewalls.
Of the speakers you've listed, honestly I'm not fond of any of them.
I'm not familiar with any of the speakers you've listed, but keep in mind that Definitive's knockoffs of old Mirage speakers require quite a bit of space from the front wall due to their bipolar radiation.
IMO, something like the Gallo speaker with two balls between a short cylindrical tweeter, mounted on the wall, would work very well in your room, with subwoofers and "room correction" EQ to compensate for Gallo's incompetent crossover designs.
