However, in a reverberant, untreated room you sacrifice smooth frequency response and natural/accurate sounding imaging. In general, the closer your speakers are to boundaries, the less dispersion you want, or the more room treatment you need.
My suggestion is to reach out to GIK Acoustics FIRST. Figure out what you want or are willing to do with the room treatment, then choose speakers.
In that room, the ML’s would be your better option if you could keep them away from the rear wall and at an angle.
Good room treatment makes your room more speaker friendly, plus, you may trade speakers many times, but no one ever trades in good acoustics. :)
Best,
